On Dec. 2, the Centers for Medicare and Medicaid Services (CMS) issued a Request for Information (RFI) on Essential Health Benefits (EHB). The RFI sought input on a proposed switch to the U.S. Pharmacopeia Drug Classification (USP DC) standard for defining the EHB prescription drug category. AMCP's comments, submitted on Jan. 31, urge CMS to refrain from switching to any alternative prescription drug classification standard.

On Dec. 21, the Department of Health and Human Services released a proposed rule titled "Patient Protection and Affordable Care Act, HHS Notice of Benefit and Payment Parameters for 2024." On Jan. 30, AMCP submitted comments which oppose two issues from the proposed rule; continuing formulary tier limitations for standardized plan options and new limits on the number of non-standardized plan options that issues may offer through the federal Marketplace.
