Medicare Part B pays for a drug like this only in specific settings, such as a drug given in a clinic or doctor’s office or used with certain medical equipment; most prescriptions filled at a pharmacy are paid by Part D.

The patient’s share under Part B (coinsurance, 20% of the limit, before deductibles and other coverage) is $0.0014 per 10 MCG.

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 mL? Is it lower than what I would pay through my insurance?
• How much is in the package I am getting? This page uses 30 mL; your package may hold a different amount.
• 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.
