On July 18, 2019, the federal register released this proposed rule from the Department for Health and Human services Centers for Medicare and Medicaid (CMS). The proposed rule would update the home health prospective payment system (HH PPS) payment rates and wage index for CY 2020; implement the Patient-Driven Groupings Model (PDGM), a revised case-mix adjustment methodology, for home health services beginning on or after January 1, 2020. This proposed rule also implements a change in the unit of payment from 60-day episodes of care to 30-day periods of care . . .
