# CMS Proposes Medicare Plan Reforms

CMS proposed CY 2028 requirements for Medicare Advantage and Part D plans that would require provider directories to be verified at least every 90 days, with accuracy scores reported to the agency. The proposal would also require annual PBM reporting, fair-market-value compensation for PBM services, and stronger protections for low-income beneficiaries, including in-network cost-sharing for enrollees who relied on inaccurate directory listings. The proposal is open for public comment for 60 days after Federal Register publication.

- Organizations serving Medicare Advantage and Part D plans should assess whether directory verification, accuracy reporting, and PBM transparency capabilities would need to change if the proposal is finalized.
- Contractors providing provider-data management, directory validation, reporting, or PBM-related services may see demand for tools and support aligned with the proposed requirements.
- Affected plans, PBMs, and industry stakeholders can submit comments during the 60-day period following Federal Register publication; no publication date is provided in the signal.
