Medicare paid 1.2× what pharmacies pay.

Part D averages every strength and form sold under “Fentanyl” into one figure, so it is not specific to this NDC.

What it is

FENTANYL 50 MCG/HR PATCH is how the CMS NADAC file names this product. The FDA NDC Directory lists it as “fentanyl” and “fentanyl transdermal”, as its NDCs’ listings variously write the nonproprietary name, under the trade name “Fentanyl system”.

FDA gives its dosage form as “patch” and “patch, extended release” and its route as transdermal.

FDA lists 4 labelers (the companies named on the label) for its NDCs, among them Mylan Pharmaceuticals Inc., SpecGx LLC and ALVOGEN.

FDA’s Established Pharmacologic Class for it is Opioid Agonist.

The NADAC file of 2026-10-14 prices it under 7 NDCs (National Drug Codes); the FDA directory lists 4 of them.

NADAC classes it as a generic drug (rate-setting class G), and does not mark it as sold over the counter.

What pharmacies pay

Pharmacies pay $9.07 for 1 patch (1 × $9.07 per EA, rounded to the cent), by the CMS NADAC file of 2026-10-14; that price took effect on 2026-09-23. That is what pharmacies pay their suppliers, not what they charge you.

NADAC’s explanation code for it: 1, calculated from the most recently completed pharmacy survey.

Questions

Why is the comparison with Medicare for FENTANYL 50 MCG/HR PATCH labelled estimated?
Beyond what the card shows, the records give these reasons: The Part D figure covers 2024-01-01 to 2024-12-31; the NADAC price is from the file of 2026-10-14. Part D spending basis, as the Part D record states it: Part D 2024 average spend per dosage unit for Fentanyl / Fentanyl: all makers, strengths, forms and routes combined, claim-weighted; gross cost incl. dispensing fees and patient pay, before rebates. Unit taken as NADAC's EA. Joined on generic name.
Why does this page start at 1 patch?
NADAC prices this product per EA, and the FDA NDC Directory lists 4 of its 7 NDCs (it does not list the other 3) as dosage forms “PATCH”, “PATCH, EXTENDED RELEASE” with route “TRANSDERMAL”. Only a tablet, capsule, lozenge or troche with route “ORAL”, or a tablet or film with route “SUBLINGUAL” or “BUCCAL”, starts at 30, and none of these is one. So the card starts at 1 patch, priced per patch, rather than guess how many make up a fill; change it to match your prescription.
