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

$15.84 estimated

$9.43 + $1.41 (15%) + $5.00 fee per fill = $15.84
