What it is

INSULIN DEGLUDEC 100 UNIT/ML VIAL is how the CMS NADAC file names this product. The FDA NDC Directory lists it as insulin degludec.

FDA gives its dosage form as injection, solution and its route as subcutaneous.

The labeler, the company named on the label, is Novo Nordisk Pharma, Inc.

FDA’s Established Pharmacologic Class for it is Insulin Analog.

The NADAC file of 2026-10-14 prices it under one NDC (National Drug Code), 73070-0400-11.

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 $113.40 for 10 mL (10 × $11.3401 per ML, rounded to the cent), by the CMS NADAC file of 2026-10-14; that price took effect on 2026-05-20. That is what pharmacies pay their suppliers, not what they charge you.

NADAC’s explanation codes for it: 4, carried forward from the previous file; 5, calculated based on package size; 6, the CMS Covered Outpatient Drug Product File S/I/N drug category was not applied when grouping drugs for the calculation.

This NDC’s NADAC was carried forward from an earlier file (NADAC explanation code 2 or 4), not newly surveyed: it took effect on 2026-05-20. The file is new; the price is not.

Questions

Why is the comparison with Medicare for INSULIN DEGLUDEC 100 UNIT/ML VIAL 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 Insulin Degludec / Insulin Degludec: all makers, strengths, forms and routes combined, claim-weighted; gross cost incl. dispensing fees and patient pay, before rebates. Unit taken as NADAC's ML. Joined on generic name.
Why does this page start at 10 mL?
NADAC prices this product per ML. The FDA NDC Directory’s package description gives 10 mL in one package for this product’s NDC (“1 VIAL, GLASS in 1 CARTON (73070-400-11) / 10 mL in 1 VIAL, GLASS”), so the card starts at one package: 10 ML. Change it to match your prescription.
