Does Medicare cover anastrozole?
Yes—Medicare can cover anastrozole if you get it through a Medicare Part D plan (or, less commonly, through Part B in limited situations). Coverage depends on your specific plan’s formulary and prior authorization rules.
Most people get prescription drugs like anastrozole under Medicare Part D because anastrozole is an oral prescription medication, and Part D covers outpatient prescription drugs.
Which part of Medicare usually covers anastrozole?
For most beneficiaries, anastrozole is covered under:
- Medicare Part D (prescription drug coverage) if it’s on your plan’s covered drug list (formulary) and you meet any requirements such as prior authorization or step therapy.
If you’re receiving cancer treatment covered under other parts of Medicare, that still typically doesn’t change anastrozole’s status as a prescription oral drug. It’s usually still handled through Part D.
What determines whether your plan will pay for anastrozole?
Coverage usually turns on:
- Your plan’s formulary tier for anastrozole (how much you pay)
- Prior authorization requirements (if the plan requires it)
- Step therapy rules (if the plan requires trying another medicine first)
- Whether you’re using a brand-name or generic version (generics are often less expensive)
What can you do if your plan doesn’t cover it?
If your Part D plan doesn’t cover anastrozole or covers it only with restrictions, common next steps include:
- Ask your doctor to request prior authorization or a formulary exception
- Ask the plan what alternative aromatase inhibitors or covered options are available under your formulary
How to check your coverage quickly
The fastest way is to look up anastrozole in your specific plan’s formulary (or contact your plan and ask):
- “Is anastrozole covered on my drug list?”
- “What tier is it on?”
- “Do I need prior authorization or step therapy?”
- “Is the generic covered, and what will my copay be?”
