The spread

<0.01× estimated

These two figures may not measure the same thing

At <0.01×, the Medicare figure is 0.2 times what pharmacies pay or less. A gap that large means the two figures may not describe the same unit or product, or the price may have changed between their dates; check what each one covers before relying on the multiple.

This product’s middle NADAC price, $14.605 per EA, is 631× the middle NADAC price of the 4 other products CMS averages under “Metformin HCl” ($0.02315 per EA), so the Part D average may mostly describe those products, not this one.

Questions

Why is the comparison with Medicare for METFORMIN HCL 750 MG TABLET labelled estimated?
Beyond what the card shows, the records give these reasons: Part D averages every strength and form sold under “Metformin HCl” into one figure, so it is not specific to this NDC. The Part D figure covers 2024-01-01 to 2024-12-31; the NADAC price is from the file of 2026-10-14. Part D spending basis, as the Part D record states it: Part D 2024 average spend per dosage unit for Metformin HCl / Metformin HCl: all makers, strengths, forms and routes combined, claim-weighted; gross cost incl. dispensing fees and patient pay, before rebates. Unit taken as NADAC's EA. Joined on generic name. 166 of 170 NADAC NDCs joined to this name are priced per EA (4 per ML): CMS's average mixes those units.
