The spread
0.04× estimated
These two figures may not measure the same thing
At 0.04×, 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.
12 labelers share HCPCS Q0162 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. (Counted once each though written more than one way: “PREFERRED PHARMACEUTICALS, INC.” and “Preferred Pharmaceuticals Inc”.)

What Medicare paid
Medicare Part B’s payment limit for HCPCS Q0162, for 2026-10-01 to 2026-12-31, comes to $0.64 for 50 mL, or $0.0128 per ML once converted to NADAC’s unit for this product.
Medicare Part B pays for this oral drug at a pharmacy only in specific circumstances CMS sets for this code; most prescriptions are paid by Part D.

2 of the product’s 5 NDCs have this Medicare figure; the other 3 do not, and the interactive card says why for each.
Medicare's price is not your 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.
- What is your cash price for 50 mL? Is it lower than what I would pay through my insurance?
- How much is in the package I am getting? This page uses 50 mL; your package may hold a different amount.
- If you have Medicare Part B: is this drug covered for me in this setting, and what is my share?
- These are questions about price, not medical advice. Do not change or stop a medicine without talking to your prescriber or pharmacist.
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 5 NDCs of this product (“1 BOTTLE, GLASS in 1 CARTON (0054-0064-47) / 50 mL in 1 BOTTLE, GLASS”), so the card starts at one package: 50 ML. Change it to match your prescription.
