(5) (A) (i) For discharges occurring during fiscal years ending on or before September 30, 1997 , the Secretary shall provide for an additional payment for a subsection (d) hospital for any discharge in a diagnosis-related group, the length of stay of which exceeds the mean length of stay for discharges within that group by a fixed number of days, or exceeds such mean length of stay by some fixed number of standard deviations, whichever is the fewer number of days. (ii) For cases which are not included in clause (i), a subsection (d) hospital may request additional payments in any case where charges, adjusted to cost, exceed a fixed multiple of the applicable DRG prospective payment rate, or exceed such other fixed dollar amount, whichever is greater, or, for discharges in fiscal years beginning on or after October 1, 1994 , exceed the sum of the applicable DRG prospective payment rate plus any amounts payable under subparagraphs (B) and (F) plus a fixed dollar amount determined by the Secretary. (iii) The amount of such additional payment under clauses (i) and (ii) shall be determined by the Secretary and shall (except as payments under clause (i) are required to be reduced to take into account the requirements of clause (v)) approximate the marginal cost of care beyond the cutoff point applicable under clause (i) or (ii). (iv) The total amount of the additional payments made under this subparagraph for discharges in a fiscal year may not be less than 5 percent nor more than 6 percent of the total payments projected or estimated to be made based on DRG prospective payment rates for discharges in that year. (v) The Secretary shall provide that— (I) the day outlier percentage for fiscal year 1995 shall be 75 percent of the day outlier percentage for fiscal year 1994; (II) the day outlier percentage for fiscal year 1996 shall be 50 percent of the day outlier percentage for fiscal year 1994; and (III) the day outlier percentage for fiscal year 1997 shall be 25 percent of the day outlier percentage for fiscal year 1994. (vi) For purposes of this subparagraph, the term “day outlier percentage” means, for a fiscal year, the percentage of the total additional payments made by the Secretary under this subparagraph for discharges in that fiscal year which are additional payments under clause (i). (B) The Secretary shall provide for an additional payment amount for subsection (d) hospitals with indirect costs of medical education, in an amount computed in the same manner as the adjustment for such costs under regulations (in effect as of January 1, 1983 ) under subsection (a)(2), except as follows: (i) The amount of such additional payment shall be determined by multiplying (I) the sum of the amount determined under paragraph (1)(A)(ii)(II) (or, if applicable, the amount determined under paragraph (1)(A)(iii)) and, for cases qualifying for additional payment under subparagraph (A)(i), the amount paid to the hospital under subparagraph (A), by (II) the indirect teaching adjustment factor described in clause (ii). (ii) For purposes of clause (i)(II), the indirect teaching adjustment factor is equal to c × (((1+r) to the nth power) −1), where “r” is the ratio of the hospital’s full-time equivalent interns and residents to beds and “n” equals .405. Subject to clause (ix), for discharges occurring— (I) on or after October 1, 1988 , and before October 1, 1997 , “c” is equal to 1.89; (II) during fiscal year 1998, “c” is equal to 1.72; (III) during fiscal year 1999, “c” is equal to 1.6; (IV) during fiscal year 2000, “c” is equal to 1.47; (V) during fiscal year 2001, “c” is equal to 1.54; (VI) during fiscal year 2002, “c” is equal to 1.6; (VII) on or after October 1, 2002 , and before April 1, 2004 , “c” is equal to 1.35; (VIII) on or after April 1, 2004 , and before October 1, 2004 , “c” is equal to 1.47; (IX) during fiscal year 2005, “c” is equal to 1.42; (X) during fiscal year 2006, “c” is equal to 1.37; (XI) during fiscal year 2007, “c” is equal to 1.32; and (XII) on or after October 1, 2007 , “c” is equal to 1.35. (iii) In determining such adjustment the Secretary shall not distinguish between those interns and residents who are employees of a hospital and those interns and residents who furnish services to a hospital but are not employees of such hospital. (iv) (I) Effective for discharges occurring on or after October 1, 1997 , and before July 1, 2010 , all the time spent by an intern or resident in patient care activities under an approved medical residency training program at an entity in a nonhospital setting shall be counted towards the determination of full-time equivalency if the hospital incurs all, or substantially all, of the costs for the training program in that setting. (II) Effective for discharges occurring on or after July 1, 2010 , all the time spent by an intern or resident in patient care activities in a nonprovider setting shall be counted towards the determination of full-time equivalency if a hospital incurs the costs of the stipends and fringe benefits of the intern or resident during the time the intern or resident spends in that setting. If more than one hospital incurs these costs, either directly or through a third party, such hospitals shall count a proportional share of the time, as determined by written agreement between the hospitals, that a resident spends training in that setting. (v) In determining the adjustment with respect to a hospital for discharges occurring on or after October 1, 1997 , the total number of full-time equivalent interns and residents in the fields of allopathic and osteopathic medicine in either a hospital or nonhospital setting may not exceed the number (or, 130 percent of such number in the case of a hospital located in a rural area) of such full-time equivalent interns and residents in the hospital with respect to the hospital’s most recent cost reporting period ending on or before December 31, 1996 . Rules similar to the rules of subsection (h)(4)(F)(ii) shall apply for purposes of this clause. The provisions of subsections (h)(4)(H)(vi), (h)(7), (h)(8), (h)(9), and (h)(10) shall apply with respect to the first sentence of this clause in the same manner as they apply with respect to subsection (h)(4)(F)(i). (vi) For purposes of clause (ii)— (I) “r” may not exceed the ratio of the number of interns and residents, subject to the limit under clause (v), with respect to the hospital for its most recent cost reporting period to the hospital’s available beds (as defined by the Secretary) during that cost reporting period, and (II) for the hospital’s cost reporting periods beginning on or after October 1, 1997 , subject to the limits described in clauses (iv) and (v), the total number of full-time equivalent residents for payment purposes shall equal the average of the actual full-time equivalent resident count for the cost reporting period and the preceding two cost reporting periods. In the case of the first cost reporting period beginning on or after October 1, 1997 , subclause (II) shall be applied by using the average for such period and the preceding cost reporting period. (vii) If any cost reporting period beginning on or after October 1, 1997 , is not equal to twelve months, the Secretary shall make appropriate modifications to ensure that the average full-time equivalent residency count pursuant to subclause (II) of clause (vi) is based on the equivalent of full twelve-month cost reporting periods. (viii) Rules similar to the rules of paragraphs (2)(F)(iv) and (4)(H) of subsection (h) shall apply for purposes of clauses (v) and (vi). (ix) For discharges occurring on or after July 1, 2005 , insofar as an additional payment amount under this subparagraph is attributable to resident positions redistributed to a hospital under subsection (h)(7)(B), in computing the indirect teaching adjustment factor under clause (ii) the adjustment shall be computed in a manner as if “c” were equal to 0.66 with respect to such resident positions. (x) For discharges occurring on or after July 1, 2011 , insofar as an additional payment amount under this subparagraph is attributable to resident positions distributed to a hospital under subsection (h)(8)(B), the indirect teaching adjustment factor shall be computed in the same manner as provided under clause (ii) with respect to such resident positions. (xi) (I) The provisions of subparagraph (K) of subsection (h)(4) shall apply under this subparagraph in the same manner as they apply under such subsection. (II) In determining the hospital’s number of full-time equivalent residents for purposes of this subparagraph, all the time spent by an intern or resident in an approved medical residency training program in non-patient care activities, such as didactic conferences and seminars, as such time and activities are defined by the Secretary, that occurs in the hospital shall be counted toward the determination of full-time equivalency if the hospital— (aa) is recognized as a subsection (d) hospital; (bb) is recognized as a subsection (d) Puerto Rico hospital; (cc) is reimbursed under a reimbursement system authorized under section 1395f(b)(3) of this title ; or (dd) is a provider-based hospital outpatient department. (III) In determining the hospital’s number of full-time equivalent residents for purposes of this subparagraph, all the time spent by an intern or resident in an approved medical residency training program in research activities that are not associated with the treatment or diagnosis of a particular patient, as such time and activities are defined by the Secretary, shall not be counted toward the determination of full-time equivalency. (xii) For discharges occurring on or after July 1, 2023 , insofar as an additional payment amount under this subparagraph is attributable to resident positions distributed to a hospital under subsection (h)(9), the indirect teaching adjustment factor shall be computed in the same manner as provided under clause (ii) with respect to such resident positions. (xiii) For discharges occurring on or after July 1, 2026 , insofar as an additional payment amount under this subparagraph is attributable to resident positions distributed to a hospital under subsection (h)(10), the indirect teaching adjustment factor shall be computed in the same manner as provided under clause (ii) with respect to such resident positions. (C) (i) The Secretary shall provide for such exceptions and adjustments to the payment amounts established under this subsection (other than under paragraph (9)) as the Secretary deems appropriate to take into account the special needs of regional and national referral centers (including those hospitals of 275 or more beds located in rural areas). A hospital which is classified as a rural hospital may appeal to the Secretary to be classified as a rural referral center under this clause on the basis of criteria (established by the Secretary) which shall allow the hospital to demonstrate that it should be so reclassified by reason of certain of its operating characteristics being similar to those of a typical urban hospital located in the same census region and which shall not require a rural osteopathic hospital to have more than 3,000 discharges in a year in order to be classified as a rural referral center. Such characteristics may include wages, scope of services, service area, and the mix of medical specialties. The Secretary shall publish the criteria not later than August 17, 1984 , for implementation by October 1, 1984 . An appeal allowed under this clause must be submitted to the Secretary (in such form and manner as the Secretary may prescribe) during the quarter before the first quarter of the hospital’s cost reporting period (or, in the case of a cost reporting period beginning during October 1984, during the first quarter of that period), and the Secretary must make a final determination with respect to such appeal within 60 days after the date the appeal was submitted. Any payment adjustments necessitated by a reclassification based upon the appeal shall be effective at the beginning of such cost reporting period. (ii) The Secretary shall provide, under clause (i), for the classification of a rural hospital as a regional referral center if the hospital has a case mix index equal to or greater than the median case mix index for hospitals (other than hospitals with approved teaching programs) located in an urban area in the same region (as defined in paragraph (2)(D)), has at least 5,000 discharges a year or, if less, the median number of discharges in urban hospitals in the region in which the hospital is located (or, in the case of a rural osteopathic hospital, meets the criterion established by the Secretary under clause (i) with respect to the annual number of discharges for such hospitals), and meets any other criteria established by the Secretary under clause (i). (D) (i) For any cost reporting period beginning on or after April 1, 1990 , with respect to a subsection (d) hospital which is a sole community hospital, payment under paragraph (1)(A) shall be— (I) an amount based on 100 percent of the hospital’s target amount for the cost reporting period, as defined in subsection (b)(3)(C), or (II) the amount determined under paragraph (1)(A)(iii), whichever results in greater payment to the hospital. (ii) In the case of a sole community hospital that experiences, in a cost reporting period compared to the previous cost reporting period, a decrease of more than 5 percent in its total number of inpatient cases due to circumstances beyond its control, the Secretary shall provide for such adjustment to the payment amounts under this subsection (other than under paragraph (9)) as may be necessary to fully compensate the hospital for the fixed costs it incurs in the period in providing inpatient hospital services, including the reasonable cost of maintaining necessary core staff and services. (iii) For purposes of this subchapter, the term “sole community hospital” means any hospital— (I) that the Secretary determines is located more than 35 road miles from another hospital, (II) that, by reason of factors such as the time required for an individual to travel to the nearest alternative source of appropriate inpatient care (in accordance with standards promulgated by the Secretary), location, weather conditions, travel conditions, or absence of other like hospitals (as determined by the Secretary), is the sole source of inpatient hospital services reasonably available to individuals in a geographic area who are entitled to benefits under part A, or (III) that is located in a rural area and designated by the Secretary as an essential access community hospital under section 1395i–4(i)(1) of this title as in effect on September 30, 1997 . (iv) The Secretary shall promulgate a standard for determining whether a hospital meets the criteria for classification as a sole community hospital under clause (iii)(II) because of the time required for an individual to travel to the nearest alternative source of appropriate inpatient care. (v) If the Secretary determines that, in the case of a hospital located in a rural area and designated by the Secretary as an essential access community hospital under section 1395i–4(i)(1) of this title as in effect on September 30, 1997 , the hospital has incurred increases in reasonable costs during a cost reporting period as a result of becoming a member of a rural health network (as defined in section 1395i–4(d) of this title ) in the State in which it is located, and in incurring such increases, the hospital will increase its costs for subsequent cost reporting periods, the Secretary shall increase the hospital’s target amount under subsection (b)(3)(C) to account for such incurred increases. (E) (i) The Secretary shall estimate the amount of reimbursement made for services described in section 1395y(a)(14) of this title with respect to which payment was made under part B in the base reporting periods referred to in paragraph (2)(A) and with respect to which payment is no longer being made. (ii) The Secretary shall provide for an adjustment to the payment for subsection (d) hospitals in each fiscal year so as appropriately to reflect the net amount described in clause (i). (F) (i) Subject to subsection (r), for discharges occurring on or after May 1, 1986 , the Secretary shall provide, in accordance with this subparagraph, for an additional payment amount for each subsection (d) hospital which— (I) serves a significantly disproportionate number of low-income patients (as defined in clause (v)), or (II) is located in an urban area, has 100 or more beds, and can demonstrate that its net inpatient care revenues (excluding any of such revenues attributable to this subchapter or State plans approved under subchapter XIX), during the cost reporting period in which the discharges occur, for indigent care from State and local government sources exceed 30 percent of its total of such net inpatient care revenues during the period. (ii) Subject to clause (ix), the amount of such payment for each discharge shall be determined by multiplying (I) the sum of the amount determined under paragraph (1)(A)(ii)(II) (or, if applicable, the amount determined under paragraph (1)(A)(iii)) and, for cases qualifying for additional payment under subparagraph (A)(i), the amount paid to the hospital under subparagraph (A) for that discharge, by (II) the disproportionate share adjustment percentage established under clause (iii) or (iv) for the cost reporting period in which the discharge occurs. (iii) The disproportionate share adjustment percentage for a cost reporting period for a hospital described in clause (i)(II) is equal to 35 percent. (iv) The disproportionate share adjustment percentage for a cost reporting period for a hospital that is not described in clause (i)(II) and that— (I) is located in an urban area and has 100 or more beds or is described in the second sentence of clause (v), is equal to the percent determined in accordance with the applicable formula described in clause (vii); (II) is located in an urban area and has less than 100 beds, is equal to 5 percent or, subject to clause (xiv) and for discharges occurring on or after April 1, 2001 , is equal to the percent determined in accordance with clause (xiii); (III) is located in a rural area and is not described in subclause (IV) or (V) or in the second sentence of clause (v), is equal to 4 percent or, subject to clause (xiv) and for discharges occurring on or after April 1, 2001 , is equal to the percent determined in accordance with clause (xii); (IV) is located in a rural area, is classified as a rural referral center under subparagraph (C), and is classified as a sole community hospital under subparagraph (D), is equal to 10 percent or, if greater, the percent determined in accordance with the applicable formula described in clause (viii) or, subject to clause (xiv) and for discharges occurring on or after April 1, 2001 , the greater of the percentages determined under clause (x) or (xi); (V) is located in a rural area, is classified as a rural referral center under subparagraph (C), and is not classified as a sole community hospital under subparagraph (D), is equal to the percent determined in accordance with the applicable formula described in clause (viii) or, subject to clause (xiv) and for discharges occurring on or after April 1, 2001 , is equal to the percent determined in accordance with clause (xi); or (VI) is located in a rural area, is classified as a sole community hospital under subparagraph (D), and is not classified as a rural referral center under subparagraph (C), is 10 percent or, subject to clause (xiv) and for discharges occurring on or after April 1, 2001 , is equal to the percent determined in accordance with clause (x). (v) In this subparagraph, a hospital “serves a significantly disproportionate number of low income patients” for a cost reporting period if the hospital has a disproportionate patient percentage (as defined in clause (vi)) for that period which equals, or exceeds— (I) 15 percent, if the hospital is located in an urban area and has 100 or more beds, (II) 30 percent (or 15 percent, for discharges occurring on or after April 1, 2001 ), if the hospital is located in a rural area and has more than 100 beds, or is located in a rural area and is classified as a sole community hospital under subparagraph (D), (III) 40 percent (or 15 percent, for discharges occurring on or after April 1, 2001 ), if the hospital is located in an urban area and has less than 100 beds, or (IV) 45 percent (or 15 percent, for discharges occurring on or after April 1, 2001 ), if the hospital is located in a rural area and is not described in subclause (II). A hospital located in a rural area and with 500 or more beds also “serves a significantly disproportionate number of low income patients” for a cost reporting period if the hospital has a disproportionate patient percentage (as defined in clause (vi)) for that period which equals or exceeds a percentage specified by the Secretary. (vi) In this subparagraph, the term “disproportionate patient percentage” means, with respect to a cost reporting period of a hospital, the sum of— (I) the fraction (expressed as a percentage), the numerator of which is the number of such hospital’s patient days for such period which were made up of patients who (for such days) were entitled to benefits under part A of this subchapter and were entitled to supplementary security income benefits (excluding any State supplementation) under subchapter XVI of this chapter, and the denominator of which is the number of such hospital’s patient days for such fiscal year which were made up of patients who (for such days) were entitled to benefits under part A of this subchapter, and (II) the fraction (expressed as a percentage), the numerator of which is the number of the hospital’s patient days for such period which consist of patients who (for such days) were eligible for medical assistance under a State plan approved under subchapter XIX, but who were not entitled to benefits under part A of this subchapter, and the denominator of which is the total number of the hospital’s patient days for such period. In determining under subclause (II) the number of the hospital’s patient days for such period which consist of patients who (for such days) were eligible for medical assistance under a State plan approved under subchapter XIX, the Secretary may, to the extent and for the period the Secretary determines appropriate, include patient days of patients not so eligible but who are regarded as such because they receive benefits under a demonstration project approved under subchapter XI. (vii) The formula used to determine the disproportionate share adjustment percentage for a cost reporting period for a hospital described in clause (iv)(I) is— (I) in the case of such a hospital with a disproportionate patient percentage (as defined in clause (vi)) greater than 20.2— (a) for discharges occurring on or after April 1, 1990 , and on or before December 31, 1990 , (P−20.2)(.65) + 5.62, (b) for discharges occurring on or after January 1, 1991 , and on or before September 30, 1993 , (P−20.2)(.7) + 5.62, (c) for discharges occurring on or after October 1, 1993 , and on or before September 30, 1994 , (P−20.2)(.8) + 5.88, and (d) for discharges occurring on or after October 1, 1994 , (P−20.2)(.825) + 5.88; or (II) in the case of any other such hospital— (a) for discharges occurring on or after April 1, 1990 , and on or before December 31, 1990 , (P−15)(.6) + 2.5, (b) for discharges occurring on or after January 1, 1991 , and on or before September 30, 1993 , (P−15)(.6) + 2.5, (c) for discharges occurring on or after October 1, 1993 , (P−15)(.65) + 2.5, where “P” is the hospital’s disproportionate patient percentage (as defined in clause (vi)). (viii) Subject to clause (xiv), the formula used to determine the disproportionate share adjustment percentage for a cost reporting period for a hospital described in clause (iv)(IV) or (iv)(V) is the percentage determined in accordance with the following formula: (P−30)(.6) + 4.0, where “P” is the hospital’s disproportionate patient percentage (as defined in clause (vi)). (ix) In the case of discharges occurring— (I) during fiscal year 1998, the additional payment amount otherwise determined under clause (ii) shall be reduced by 1 percent; (II) during fiscal year 1999, such additional payment amount shall be reduced by 2 percent; (III) during fiscal years 2000 and 2001, such additional payment amount shall be reduced by 3 percent and 2 percent, respectively; (IV) during fiscal year 2002, such additional payment amount shall be reduced by 3 percent; and (V) during fiscal year 2003 and each subsequent fiscal year, such additional payment amount shall be reduced by 0 percent. (x) Subject to clause (xiv), for purposes of clause (iv)(VI) (relating to sole community hospitals), in the case of a hospital for a cost reporting period with a disproportionate patient percentage (as defined in clause (vi)) that— (I) is less than 19.3, the disproportionate share adjustment percentage is determined in accordance with the following formula: (P−15)(.65) + 2.5; (II) is equal to or exceeds 19.3, but is less than 30.0, such adjustment percentage is equal to 5.25 percent; or (III) is equal to or exceeds 30, such adjustment percentage is equal to 10 percent, where “P” is the hospital’s disproportionate patient percentage (as defined in clause (vi)). (xi) Subject to clause (xiv), for purposes of clause (iv)(V) (relating to rural referral centers), in the case of a hospital for a cost reporting period with a disproportionate patient percentage (as defined in clause (vi)) that— (I) is less than 19.3, the disproportionate share adjustment percentage is determined in accordance with the following formula: (P−15)(.65) + 2.5; (II) is equal to or exceeds 19.3, but is less than 30.0, such adjustment percentage is equal to 5.25 percent; or (III) is equal to or exceeds 30, such adjustment percentage is determined in accordance with the following formula: (P−30)(.6) + 5.25, where “P” is the hospital’s disproportionate patient percentage (as defined in clause (vi)). (xii) Subject to clause (xiv), for purposes of clause (iv)(III) (relating to small rural hospitals generally), in the case of a hospital for a cost reporting period with a disproportionate patient percentage (as defined in clause (vi)) that— (I) is less than 19.3, the disproportionate share adjustment percentage is determined in accordance with the following formula: (P−15)(.65) + 2.5; or (II) is equal to or exceeds 19.3, such adjustment percentage is equal to 5.25 percent, where “P” is the hospital’s disproportionate patient percentage (as defined in clause (vi)). (xiii) Subject to clause (xiv), for purposes of clause (iv)(II) (relating to urban hospitals with less than 100 beds), in the case of a hospital for a cost reporting period with a disproportionate patient percentage (as defined in clause (vi)) that— (I) is less than 19.3, the disproportionate share adjustment percentage is determined in accordance with the following formula: (P−15)(.65) + 2.5; or (II) is equal to or exceeds 19.3, such adjustment percentage is equal to 5.25 percent, where “P” is the hospital’s disproportionate patient percentage (as defined in clause (vi)). (xiv) (I) In the case of discharges occurring on or after April 1, 2004 , subject to subclause (II), there shall be substituted for the disproportionate share adjustment percentage otherwise determined under clause (iv) (other than subclause (I)) or under clause (viii), (x), (xi), (xii), or (xiii), the disproportionate share adjustment percentage determined under clause (vii) (relating to large, urban hospitals). (II) Under subclause (I), the disproportionate share adjustment percentage shall not exceed 12 percent for a hospital that is not classified as a rural referral center under subparagraph (C) or, in the case of discharges occurring on or after October 1, 2006 , as a medicare-dependent, small rural hospital under subparagraph (G)(iv). (G) (i) For any cost reporting period beginning on or after April 1, 1990 , and before October 1, 1994 , or discharges occurring on or after October 1, 1997 , and before January 1, 2025 , in the case of a subsection (d) hospital which is a medicare-dependent, small rural hospital, payment under paragraph (1)(A) shall be equal to the sum of the amount determined under clause (ii) and the amount determined under paragraph (1)(A)(iii). (ii) The amount determined under this clause is— (I) for discharges occurring during the 36-month period beginning with the first day of the cost reporting period that begins on or after April 1, 1990 , the amount by which the hospital’s target amount for the cost reporting period (as defined in subsection (b)(3)(D)) exceeds the amount determined under paragraph (1)(A)(iii); and (II) for discharges occurring during any subsequent cost reporting period (or portion thereof) and before October 1, 1994 , or discharges occurring on or after October 1, 1997 , and before January 1, 2025 , 50 percent (or 75 percent in the case of discharges occurring on or after October 1, 2006 ) of the amount by which the hospital’s target amount for the cost reporting period or for discharges in the fiscal year (as defined in subsection (b)(3)(D)) exceeds the amount determined under paragraph (1)(A)(iii). (iii) In the case of a medicare dependent, small rural hospital that experiences, in a cost reporting period compared to the previous cost reporting period, a decrease of more than 5 percent in its total number of inpatient cases due to circumstances beyond its control, the Secretary shall provide for such adjustment to the payment amounts under this subsection (other than under paragraph (9)) as may be necessary to fully compensate the hospital for the fixed costs it incurs in the period in providing inpatient hospital services, including the reasonable cost of maintaining necessary core staff and services. (iv) The term “medicare-dependent, small rural hospital” means, with respect to any cost reporting period to which clause (i) applies, any hospital— (I) that is located in— (aa) a rural area; or (bb) a State with no rural area (as defined in paragraph (2)(D)) and satisfies any of the criteria in subclause (I), (II), or (III) of paragraph (8)(E)(ii), (II) that has not more than 100 beds, (III) that is not classified as a sole community hospital under subparagraph (D), and (IV) for which not less than 60 percent of its inpatient days or discharges during the cost reporting period beginning in fiscal year 1987, or two of the three most recently audited cost reporting periods for which the Secretary has a settled cost report, were attributable to inpatients entitled to benefits under part A. Subclause (I)(bb) shall apply for purposes of payment under clause (ii) only for discharges of a hospital occurring on or after the effective date of a determination of medicare-dependent small rural hospital status made by the Secretary with respect to the hospital after February 9, 2018 . For purposes of applying subclause (II) of paragraph (8)(E)(ii) under subclause (I)(bb), such subclause (II) shall be applied by inserting “as of January 1, 2018 ,” after “such State” each place it appears. (H) The Secretary may provide for such adjustments to the payment amounts under this subsection as the Secretary deems appropriate to take into account the unique circumstances of hospitals located in Alaska and Hawaii. (I) (i) The Secretary shall provide by regulation for such other exceptions and adjustments to such payment amounts under this subsection as the Secretary deems appropriate. (ii) In making adjustments under clause (i) for transfer cases (as defined by the Secretary) in a fiscal year, not taking in account the effect of subparagraph (J), the Secretary may make adjustments to each of the average standardized amounts determined under paragraph (3) to assure that the aggregate payments made under this subsection for such fiscal year are not greater or lesser than those that would have otherwise been made in such fiscal year. (J) (i) The Secretary shall treat the term “transfer case” (as defined in subparagraph (I)(ii)) as including the case of a qualified discharge (as defined in clause (ii)), which is classified within a diagnosis-related group described in clause (iii), and which occurs on or after October 1, 1998 . In the case of a qualified discharge for which a substantial portion of the costs of care are incurred in the early days of the inpatient stay (as defined by the Secretary), in no case may the payment amount otherwise provided under this subsection exceed an amount equal to the sum of— (I) 50 percent of the amount of payment under this subsection for transfer cases (as established under subparagraph (I)(i)), and (II) 50 percent of the amount of payment which would have been made under this subsection with respect to the qualified discharge if no transfer were involved. (ii) For purposes of clause (i), subject to clause (iii), the term “qualified discharge” means a discharge classified with a diagnosis-related group (described in clause (iii)) of an individual from a subsection (d) hospital, if upon such discharge the individual— (I) is admitted as an inpatient to a hospital or hospital unit that is not a subsection (d) hospital for the provision of inpatient hospital services; (II) is admitted to a skilled nursing facility; (III) is provided home health services from a home health agency, if such services relate to the condition or diagnosis for which such individual received inpatient hospital services from the subsection (d) hospital, and if such services are provided within an appropriate period (as determined by the Secretary); (IV) for discharges occurring on or after October 1, 2018 , is provided hospice care by a hospice program; or (V) for discharges occurring on or after October 1, 2000 , the individual receives post discharge services described in clause (iv)(I). (iii) Subject to clause (iv), a diagnosis-related group described in this clause is— (I) 1 of 10 diagnosis-related groups selected by the Secretary based upon a high volume of discharges classified within such groups and a disproportionate use of post discharge services described in clause (ii); and (II) a diagnosis-related group specified by the Secretary under clause (iv)(II). (iv) The Secretary shall include in the proposed rule published under subsection (e)(5)(A) for fiscal year 2001, a description of the effect of this subparagraph. The Secretary shall include in the proposed rule published for fiscal year 2019, a description of the effect of clause (ii)(IV). The Secretary may include in the proposed rule (and in the final rule published under paragraph (6)) for fiscal year 2001 or a subsequent fiscal year, a description of— (I) post-discharge services not described in subclauses (I), (II), (III), and, in the case of proposed and final rules for fiscal year 2019 and subsequent fiscal years, (IV) of clause (ii), the receipt of which results in a qualified discharge; and (II) diagnosis-related groups described in clause (iii)(I) in addition to the 10 selected under such clause. (K) (i) Effective for discharges beginning on or after October 1, 2001 , the Secretary shall establish a mechanism to recognize the costs of new medical services and technologies under the payment system established under this subsection. Such mechanism shall be established after notice and opportunity for public comment (in the publications required by subsection (e)(5) for a fiscal year or otherwise). Such mechanism shall be modified to meet the requirements of clause (viii). (ii) The mechanism established pursuant to clause (i) shall— (I) apply to a new medical service or technology if, based on the estimated costs incurred with respect to discharges involving such service or technology, the DRG prospective payment rate otherwise applicable to such discharges under this subsection is inadequate (applying a threshold specified by the Secretary that is the lesser of 75 percent of the standardized amount (increased to reflect the difference between cost and charges) or 75 percent of one standard deviation for the diagnosis-related group involved); (II) provide for the collection of data with respect to the costs of a new medical service or technology described in subclause (I) for a period of not less than two years and not more than three years beginning on the date on which an inpatient hospital code is issued with respect to the service or technology; (III) provide for additional payment to be made under this subsection with respect to discharges involving a new medical service or technology described in subclause (I) that occur during the period described in subclause (II) in an amount that adequately reflects the estimated average cost of such service or technology; and (IV) provide that discharges involving such a service or technology that occur after the close of the period described in subclause (II) will be classified within a new or existing diagnosis-related group with a weighting factor under paragraph (4)(B) that is derived from cost data collected with respect to discharges occurring during such period. (iii) For purposes of clause (ii)(II), the term “inpatient hospital code” means any code that is used with respect to inpatient hospital services for which payment may be made under this subsection and includes an alphanumeric code issued under the International Classification of Diseases, 9th Revision, Clinical Modification (“ICD–9–CM”) and its subsequent revisions. (iv) For purposes of clause (ii)(III), the term “additional payment” means, with respect to a discharge for a new medical service or technology described in clause (ii)(I), an amount that exceeds the prospective payment rate otherwise applicable under this subsection to discharges involving such service or technology that would be made but for this subparagraph. (v) The requirement under clause (ii)(III) for an additional payment may be satisfied by means of a new-technology group (described in subparagraph (L)), an add-on payment, a payment adjustment, or any other similar mechanism for increasing the amount otherwise payable with respect to a discharge under this subsection. The Secretary may not establish a separate fee schedule for such additional payment for such services and technologies, by utilizing a methodology established under subsection (a) or (h) of section 1395m of this title to determine the amount of such additional payment, or by other similar mechanisms or methodologies. (vi) For purposes of this subparagraph and subparagraph (L), a medical service or technology will be considered a “new medical service or technology” if the service or technology meets criteria established by the Secretary after notice and an opportunity for public comment. (vii) Under the mechanism under this subparagraph, the Secretary shall provide for the addition of new diagnosis and procedure codes in April 1 of each year, but the addition of such codes shall not require the Secretary to adjust the payment (or diagnosis-related group classification) under this subsection until the fiscal year that begins after such date. (viii) The mechanism established pursuant to clause (i) shall be adjusted to provide, before publication of a proposed rule, for public input regarding whether a new service or technology represents an advance in medical technology that substantially improves the diagnosis or treatment of individuals entitled to benefits under part A as follows: (I) The Secretary shall make public and periodically update a list of all the services and technologies for which an application for additional payment under this subparagraph is pending. (II) The Secretary shall accept comments, recommendations, and data from the public regarding whether the service or technology represents a substantial improvement. (III) The Secretary shall provide for a meeting at which organizations representing hospitals, physicians, such individuals, manufacturers, and any other interested party may present comments, recommendations, and data to the clinical staff of the Centers for Medicare & Medicaid Services before publication of a notice of proposed rulemaking regarding whether service or technology represents a substantial improvement. (ix) Before establishing any add-on payment under this subparagraph with respect to a new technology, the Secretary shall seek to identify one or more diagnosis-related groups associated with such technology, based on similar clinical or anatomical characteristics and the cost of the technology. Within such groups the Secretary shall assign an eligible new technology into a diagnosis-related group where the average costs of care most closely approximate the costs of care of using the new technology. No add-on payment under this subparagraph shall be made with respect to such new technology and this clause shall not affect the application of paragraph (4)(C)(iii). (L) (i) In establishing the mechanism under subparagraph (K), the Secretary may establish new-technology groups into which a new medical service or technology will be classified if, based on the estimated average costs incurred with respect to discharges involving such service or technology, the DRG prospective payment rate otherwise applicable to such discharges under this subsection is inadequate. (ii) Such groups— (I) shall not be based on the costs associated with a specific new medical service or technology; but (II) shall, in combination with the applicable standardized amounts and the weighting factors assigned to such groups under paragraph (4)(B), reflect such cost cohorts as the Secretary determines are appropriate for all new medical services and technologies that are likely to be provided as inpatient hospital services in a fiscal year. (iii) The methodology for classifying specific hospital discharges within a diagnosis-related group under paragraph (4)(A) or a new-technology group shall provide that a specific hospital discharge may not be classified within both a diagnosis-related group and a new-technology group. (M) (i) For cost reporting periods beginning on or after October 1, 2020 , in the case of a subsection (d) hospital that furnishes an allogeneic hematopoietic stem cell transplant to an individual during such a period, payment to such hospital for hematopoietic stem cell acquisition shall be made on a reasonable cost basis. The items included in such hematopoietic stem cell acquisition shall be specified by the Secretary through rulemaking. (ii) For purposes of this subparagraph, the term “allogeneic hematopoietic stem cell transplant” means, with respect to an individual, the intravenous infusion of hematopoietic cells derived from bone marrow, peripheral blood stem cells, or cord blood, but not including embryonic stem cells, of a donor to an individual that are or may be used to restore hematopoietic function in such individual having an inherited or acquired deficiency or defect.
