On January 6, 2022, the Centers for Medicare and Medicaid Services (CMS) released a proposed rule regarding Contract Year 2023 Policy and Technical Changes to the Medicare Advantage and Medicare Prescription Drug Benefit Programs, marking the Biden administration’s first proposed rule on these topics. The proposed rule includes proposed changes to the manner in which pharmacy price concessions are accounted for in the Part D benefit, the timing of network adequacy reviews for Medicare Advantage Organization (MAO) applicants, and new rules regarding oversight of third-party marketing organizations. The proposed rule also reverses course on some policy changes that were initiated under the prior administration, including changes related to medical loss ratio (MLR) reporting and past performance evaluations. The proposed rule includes proposed policy updates for Dual Eligible Special Needs Plans (D-SNPs) and a few provisions related to the ongoing COVID-19 public health emergency (PHE).
