42 CFR 425.606 - Calculation of shared savings and losses under Track 2.
(a)General rule. For each performance year, CMS determines whether the estimated average per capita Medicare expenditures under the ACO for Medicare fee-for-service beneficiaries for Parts A and B services are above or below the updated benchmark determined under § 425.602. In order to qualify for a shared savings payment under Track 2, or to be responsible for sharing losses with CMS, an ACO's average per capita Medicare expenditures under the ACO for Medicare fee-for-service beneficiaries for Parts A and B services for the performance year must be below or above the updated benchmark, respectively, by at least the minimum savings or loss rate under paragraph (b) of this section.
(1)Newly assigned beneficiaries. CMS uses an ACO's HCC prospective risk score to adjust the benchmark for changes in severity and case mix in this population.
(2)Continuously assigned beneficiaries.
(ii) If the prospective HCC risk score is lower in the performance year for this population, CMS will adjust the benchmark for changes in severity and case mix for this population using this lower prospective HCC risk score.
(3) Assigned beneficiary changes in demographics and health status are used to adjust benchmark expenditures as described in § 425.602(a). In adjusting the benchmark for health status and demographic changes CMS makes separate adjustments for each of the following populations of beneficiaries:
(i) For performance years before 2017 to minimize variation from catastrophically large claims, CMS truncates an assigned beneficiary's total annual Parts A and B fee-for-service per capita expenditures at the 99th percentile of national Medicare fee-for-service expenditures as determined for each performance year.
(ii) For the 2017 performance year and subsequent performance years, to minimize variation from catastrophically large claims, CMS truncates an assigned beneficiary's total annual Parts A and B fee-for-service per capita expenditures at the 99th percentile of national Medicare fee-for-service expenditures as determined for the applicable performance year for assignable beneficiaries identified for the 12-month calendar year corresponding to the performance year.
(6) Calculations of the ACO's expenditures will include the payment amounts included in Part A and B fee-for-service claims.
(i) These calculations will exclude indirect medical education (IME) and disproportionate share hospital (DSH) payments.
(A) For performance years beginning before 2018, these calculations will take into consideration all individually beneficiary identifiable payments, including interim payments, made under a demonstration, pilot or time limited program.
(B) For performance year 2018 and subsequent performance years, these calculations will take into consideration individually beneficiary identifiable final payments made under a demonstration, pilot or time limited program.
(7) In order to qualify for a shared savings payment, the ACO's average per capita Medicare expenditures for the performance year must be below the applicable updated benchmark by at least the minimum savings rate established for the ACO under paragraph (b) of this section.
(b)Minimum savings or loss rate. (1)(i) For agreement periods beginning in 2012 through 2015, the ACO's MSR and MLR are set at 2 percent.
(ii) For agreement periods beginning in 2016 and subsequent years, as part of the ACO's application for, or renewal of, program participation, the ACO must choose from the following options for establishing the MSR/MLR for the duration of the agreement period:
(A) Zero percent MSR/MLR.
(B) Symmetrical MSR/MLR in a 0.5 percent increment between 0.5-2.0 percent.
(C) Symmetrical MSR/MLR that varies, based on the number of beneficiaries assigned to the ACO under subpart E of this part. The MSR for an ACO under Track 2 is the same as the MSR that would apply in the one-sided model under § 425.604(b) and is based on the number of assigned beneficiaries. The MLR under Track 2 is equal to the negative MSR.
(2) To qualify for shared savings under Track 2, an ACO's average per capita Medicare expenditures for the performance year must be below its updated benchmark costs for the year by at least the MSR established for the ACO.
(3) To be responsible for sharing losses with the Medicare program, an ACO's average per capita Medicare expenditures for the performance year must be above its updated benchmark costs for the year by at least the MLR established for the ACO.
(c)Qualification for shared savings payment. To qualify for shared savings, an ACO must meet the minimum savings rate requirement established under paragraph (b) of this section, meet the minimum quality performance standards established under § 425.502 of this part, and otherwise maintain its eligibility to participate in the Shared Savings Program under this part.
(d)Final sharing rate. An ACO that meets all the requirements for receiving shared savings payments under Track 2 will receive a shared savings payment of up to 60 percent of all the savings under the updated benchmark, as determined on the basis of its quality performance under § 425.502 of this part (up to the performance payment limit described in paragraph (e)(2) of this section).
(1) If an ACO qualifies for savings by meeting or exceeding the MSR, the final sharing rate will apply to an ACO's savings on a first dollar basis.
(2) The amount of shared savings an eligible ACO receives under Track 2 may not exceed 15 percent of its updated benchmark.
(f)Shared loss rate. The shared loss rate -
(1) For an ACO that is required to share losses with the Medicare program for expenditures over the updated benchmark, the amount of shared losses is determined based on the inverse of its final sharing rate described in § 425.606(d) (that is, 1 minus the final shared savings rate determined under § 425.606(d) of this part); and
(2) May not exceed 60 percent.
(2) 7.5 percent in the second performance year.
(3) 10 percent in the third and any subsequent performance year.
(h)Notification of savings and losses.
(i)Extreme and uncontrollable circumstances. For performance year 2017, the following adjustment is made in calculating the amount of shared losses, after the application of the shared loss rate in paragraph (f) of this section and the loss recoupment limit in paragraph (g) of this section.
(2) CMS reduces the amount of the ACO's shared losses by an amount determined by multiplying the shared losses by the percentage of the total months in the performance year affected by an extreme and uncontrollable circumstance, and the percentage of the ACO's assigned beneficiaries who reside in an area affected by an extreme and uncontrollable circumstance.
(i) Whether an extreme and uncontrollable circumstance has occurred; and
(ii) The affected areas.
(4) CMS has sole discretion to determine the time period during which an extreme and uncontrollable circumstance occurred and the percentage of the ACO's assigned beneficiaries residing in the affected areas.
