What Part D spending measures · Which Medicare figure OpenBill compares · How the spread is worked out
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 1 mL? Is it lower than what I would pay through my insurance?
- How much is in the package I am getting? This page uses 1 mL; your package may hold a different amount.
- If you have Medicare Part D: what is my plan’s copay or coinsurance for it? The Part D average on this page is not what you pay.
- These are questions about price, not medical advice. Do not change or stop a medicine without talking to your prescriber or pharmacist.
Questions
- Why is the comparison with Medicare for CROMOLYN 100 MG/5 ML ORAL CONC 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 Cromolyn Sodium* / Cromolyn Sodium: 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. *: CMS says this average reflects multiple routes of administration, which may have different unit prices. Only NADAC NDCs whose FDA route includes ORAL point at this name (3 of the 8 the name join matched); NDCs of another route or with no known FDA route do not.
- Why does this page start at 1 mL?
- The FDA package descriptions of this product’s NDCs give different amounts (480 mL, 3,840 mL). So the card starts at 1 ML; change it to match your prescription.
