On June 9, 2023, CMS will publish its Final Action regarding the treatment of Part C days in the Medicare DSH calculation in resolution of Allina II.
CMS will issue NPR's that count Part C days in the Medicare Fraction of the DPP calculation. CMS finds support for its position that Part C days are covered days for which beneficiaries are entitled to Part A benefits in the recent Empire decision which permitted CMS to consider unpaid Medicare days as entitled to Part A and count them in the Medicare Fraction of the DPP calculation.
The unpublished version is currently available at 2023-12308.pdf (federalregister.gov).
