The numbers behind every sentence are on this page below — and the Watch button emails you when any of them move.

Medicare Part D

Matched to CMS's representative package for this drug (NDC 00591-3851-01) — same generic, strength, and dosage form. CMS prices one NDC per drug concept, not every package.

ⓘ How this was built

Data sources

CMS quarterly Prescription Drug Plan Formulary & Pricing files (SPUF)

Method

Negotiated 30-day point-of-sale unit prices and formulary terms aggregated across every unsuppressed Part D and MA-PD plan for the quarter shown. Point of sale means gross of confidential rebates. CMS publishes one representative NDC per drug concept (RxCUI) rather than every package, so these figures come from CMS's representative package for the same drug — matched on generic name, strength, and dosage form. Estimated from MedPAC's program-wide rebate aggregates (June 2023: DIR = 29% of gross Part D spending; brand rebates ≈ 25–40% of gross, generics minimal). Actual rebates are confidential and vary widely by drug — this is a range, not a fact about this drug.
