# Critical SSI Error Identified in Post-Advocate Christ Remand Letter Review

Following the recent Supreme Court decision in *Advocate Christ Medical Center v. Kennedy (HHS*), we’re seeing a wave of remand and settlement letters being issued for old Cost Report Years. These actions aim to implement the Court’s ruling across affected providers.

 

In reviewing one such letter for a client, GDS identified a significant issue: the Medicare Administrative Contractor (MAC) proposed to use an incorrect SSI (Supplemental Security Income) ratio. While the value referenced did match a published CMS SSI chart and corresponded to the provider’s correct fiscal year, it was taken from an **incorrect chart**.

 

Had this error gone unnoticed, it would have resulted in a loss of nearly **$200,000** for the provider.

This review underscores the importance of a thorough review of all data elements in remand or settlement letters, particularly when it comes to SSI ratios—which have a direct impact on DSH payments and related reimbursements.

GDS is a leading expert in SSI Ratios (including realignments), Medicare DSH, 340B qualification, and many other Reimbursement and Revenue Cycle matters. Contact Adam Blackwell for a complimentary conversation.
