20 CFR § 404.1519k - Purchase of medical examinations, laboratory tests, and other services.
We may purchase medical examinations, including psychiatric and psychological examinations, X-rays and laboratory tests (including specialized tests, such as pulmonary function studies, electrocardiograms, and stress tests) from a medical source.
(a) The rate of payment for purchasing medical or other services necessary to make determinations of disability may not exceed the highest rate paid by Federal or public agencies in the State for the same or similar types of service. See §§ 404.1624 and 404.1626 of this part.
(b) If a physician's bill or a request for payment for a physician's services includes a charge for a laboratory test for which payment may be made under this part, the amount payable with respect to the test shall be determined as follows:
(1) If the bill or request for payment indicates that the test was personally performed or supervised by the physician who submitted the bill (or for whose services the request for payment was made) or by another physician with whom that physician shares his or her practice, the payment will be based on the physician's usual and customary charge for the test or the rates of payment which the State uses for purchasing such services, whichever is the lesser amount.
(2) If the bill or request for payment indicates that the test was performed by an independent laboratory, the amount of reimbursement will not exceed the billed cost of the independent laboratory or the rate of payment which the State uses for purchasing such services, whichever is the lesser amount. A nominal payment may be made to the physician for collecting, handling and shipping a specimen to the laboratory if the physician bills for such a service. The total reimbursement may not exceed the rate of payment which the State uses for purchasing such services.
(c) The State will assure that it can support the rate of payment it uses. The State shall also be responsible for monitoring and overseeing the rate of payment it uses to ensure compliance with paragraphs (a) and (b) of this section.
