The Michigan Department of Health and Human Services (MDHHS) recently notified hospitals about an issue with the Medicare crossover files from the Centers for Medicare & Medicaid Services (CMS) that impacts CMS files from May 4 to May 23, 2023. Since the MDHHS was not able to load Medicare crossover files received from the CMS during that timeframe, hospitals may need to submit crossover claims. Hospitals are encouraged to review their Medicare Explanation of Benefit (EOB) to determine which claims are impacted and submit them directly to Michigan Medicaid, as necessary. The MDHHS indicated this appears to be a one-time issue and will continue to track and provide future updates, if necessary.
Members with questions should contact Vickie Kunz at the MHA.
