Medicare
We don’t know yet
No Medicare reference price. Part D: OpenBill did not match this NDC to a usable Medicare Part D spending row. Either Part D has none for it, or the rows that share its name could not safely be tied to it (for example, they mix units, routes or release forms, or the drug is sold over the counter, which Part D does not cover). Part B: This NDC is not in the current quarter’s Medicare Part B NDC-HCPCS crosswalk, so it has no Part B payment limit.
The spread
We don’t know yet
There is no Medicare figure to compare with, so there is no spread.
Cost-plus estimate
$22.66 estimated
$15.36 + $2.30 (15%) + $5.00 fee per fill = $22.66

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 300 mL? Is it lower than what I would pay through my insurance?
- How much is in the package I am getting? This page uses 300 mL; your package may hold a different amount.
- 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 300 mL?
- NADAC prices this product per ML. In the FDA NDC Directory, NDC 00121-1154-40 (“4 TRAY in 1 CASE (0121-1154-40) / 10 CUP, UNIT-DOSE in 1 TRAY / 30 mL in 1 CUP, UNIT-DOSE (0121-1154-30)”) is a shipping case of 4 trays, 1,200 mL in all: a wholesale pack of identical units, so OpenBill counts one tray of it. It does not list one of this product’s NDCs. So the card starts at one tray: 300 ML. Change it to match your prescription.
