Supplemental Security Income Ratio Realignment for Cost Reporting Periods Starting Before 10/1/2013


On 6/9/2023, in response to the Supreme Court’s ruling in Azar v. Allina Health Services, 139 S. Ct. 1804 (2019), the CMS issued a final rule (CMS-1739-F) that established a policy on the treatment of Part C days for purposes of calculating a hospital’s DPP for cost reporting periods starting before 10/1/2013 (that is, for cost reporting periods starting before Federal FY 2014) (88 FR 37772). In this rule, CMS expressed its view that, in light of Becerra v. Empire Health Foundation, for Valley Hospital Medical Center, 597 U.S. 424, 435 (June 24, 2022), it is clear that the DSH statute requires CMS to count Part C days in the Medicare fraction because Medicare beneficiaries remain “entitled to [Medicare Part A]” regardless of whether they enroll in Part C, and thus there was no statutory gap to fill that would require rulemaking under Allina. Nonetheless, because Empire did not squarely address whether Part C enrollees remain “entitled to Part A,” CMS adopted, through retroactive rulemaking for cost reporting periods starting before 10/1/2013, the same policy of including Part C days in the Medicare fraction (also known as the “SSI fraction” or “SSI ratio”) that was prospectively adopted in the FY 2014 IPPS final rule. Under the policy articulated in this rule, CMS will calculate a hospital’s DPP by including Part C days in the Medicare fraction and excluding them from the numerator of the Medicaid fraction. 
42 CFR 412.106(b)(3) allows a hospital the opportunity to request to have its SSI ratio realigned based on its cost reporting period (as opposed to the Federal FY). Under this regulation, a realignment will be performed once per hospital per cost reporting period, and the resulting percentage becomes the hospital’s official SSI ratio for that period. After the Supreme Court’s Allina decision, CMS held processing of requests for SSI ratio realignment for cost reporting periods starting before FY 2014 due to a lack of policy established through notice-and-comment rulemaking regarding the treatment of Part C days for that period of time. With the issuance of the final rule (CMS-1739-F), the processing of realignment requests for cost reporting periods starting before FY 2014 will resume. 

This letter explains the process for hospitals to confirm or make new realignment requests for cost reporting periods starting before 10/1/2013.

Realignment Requests for Cost Reporting Periods Starting Before 10/1/2013 
Existing Realignment Requests:
For any realignment requests for cost reporting periods starting before 10/1/2013 that the provider submitted to its MAC prior to 7/31/2024, providers MUST confirm these existing requests with their MAC before they can be processed. 

New Realignment Requests: In addition to confirming existing requests, providers may also request realignments for other cost reporting periods starting before 10/1/2013 in accordance with CMS regulations. 

Information to Send to MACs for Existing or New Realignment Requests: To confirm an existing request or make a new request for cost reporting periods starting before 10/1/2013, the provider must send a written notification to the MAC which contains the following information: 

  • Cost report begin date 
  • Cost report end date 

The MAC will verify the written notification it received from the provider and determine DSH payments for verified realignment requests in accordance with CR 13413 (posted on the 2024 Transmittals page on the CMS website). 

Finally, we note that, in accordance with the existing rules regarding realignment requests (42 CFR 412.106(b)(3)), once a hospital has confirmed its request for realignment of cost reporting periods starting before 10/1/2013 (in the case of requests made prior to 7/31/2024 or made a new request for such a reporting period, that request may not be withdrawn. The realigned ratio for the cost reporting period (posted on CMS' DSH website) will be the hospital’s ratio, regardless of whether the ratio is higher or lower than the Federal FY ratio.
