The spread
0.59× derived
Medicare pays 41% less than pharmacies pay.
Derived because only one labeler, Breckenridge Pharmaceutical, Inc., is listed for HCPCS Q0166 on the CMS crosswalk, so the payment limit comes from that company’s own products under the code, not an average across companies.

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 30 tablets? Is it lower than what I would pay through my insurance?
- If you have Medicare Part B: is this drug covered for me in this setting, and what is my share?
- These are questions about price, not medical advice. Do not change or stop a medicine without talking to your prescriber or pharmacist.
