The Medicare Payment Advisory Commission (MedPAC) is launching a study to determine whether the Patient-Driven Groupings Model (PDGM) accurately aligns home health payments with patient care costs. ^[3] MedPAC is a nonpartisan agency to the legislative branch that advises Congress on Medicare. ^[5] The commission is also planning to investigate potential coding distortions, payment inaccuracies, and whether financial incentives influence patient selection by nursing home providers in fee-for-service Medicare systems. ^[1] MedPAC's work plan aims to determine whether Medicare payments accurately reflect patients' clinical complexity and care costs, covering the period from 2021 to 2025. ^[2] CMS' proposed CY2027 Medicare home health payment rule included a 3% temporary adjustment, tied to the agency's effort to recoup what it considers PDGM-related overpayments. ^[4]
