Matched to CMS's representative package for this drug (NDC 60793-0115-01) — same generic, strength, and dosage form. CMS prices one NDC per drug concept, not every package.
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.
Pipeline and calculations built by Claude (Fable 5) from the public datasets above. Educational only — verify against primary sources before acting.
*No drug-level rebate is public — the estimate applies MedPAC's program-wide brand rebate range to this drug's gross price. Tracked here for 10 quarters since 2024.
No NADAC pricing on file for this NDC — NADAC covers drugs dispensed by retail community pharmacies.
Not scored — fragility is computed for NADAC-priced NDCs.
