The spread

1.4× estimated

Medicare pays 1.4× what pharmacies pay.

10 labelers share HCPCS J3260 on the CMS crosswalk, so its payment limit is an average across all their products billed under that code, not this NDC’s own price.

What to ask at the counter

None of these figures is your price: what you pay depends on your pharmacy, your insurance, coupons and discounts.

Questions

Why does this page start at 50 mL?
NADAC prices this product per ML. The FDA NDC Directory’s package description gives 50 mL in one package for all 4 NDCs of this product (“25 VIAL, MULTI-DOSE in 1 TRAY (0409-3578-01) / 2 mL in 1 VIAL, MULTI-DOSE (0409-3578-11)”), so the card starts at one package: 50 ML. Change it to match your prescription.
