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

$5.03 – $5.07 estimated

NADAC for the pack + 15% + $5.00 fee per fill

This is a model, not a price any pharmacy quoted. Shipping is not included. For a pack this cheap, the $5.00 fee is most of the estimate. How it is worked out

What Medicare paid

Which Medicare figure OpenBill compares · How Part D is matched · How Part B is matched

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 1 mL?
The FDA package descriptions of this product’s NDCs give different amounts (118 mL, 120 mL, 473 mL). So the card starts at 1 ML; change it to match your prescription.
