Does Medicare cover Firdapse (amifampridine)?
Medicare coverage for Firdapse depends on why it’s prescribed and how it’s billed, because Medicare does not cover every medication for every diagnosis automatically. Firdapse is typically considered under Parts D (outpatient prescription drugs) or sometimes under Part B in special situations, but eligibility is determined by your plan formulary and coverage rules (including whether the medication is considered medically necessary for the specific condition).
Will my Medicare Part D plan cover Firdapse?
For most people, the key question is your Medicare Part D plan’s formulary. Coverage can vary by plan, and you may need:
- Prior authorization (plan approval before it pays)
- Step therapy (trying another treatment first)
- Quantity limits
- A coverage determination based on diagnosis and documentation
What if it’s covered—what will I pay?
If Firdapse is covered under your Part D plan, your cost usually depends on where you are in the plan’s structure (deductible, copays/coinsurance, and any coverage gap/catastrophic coverage rules). Your plan will specify the exact tier cost or share.
When would Medicare Part B cover a prescription drug like this?
Medicare Part B can apply to certain drugs when they are administered by a clinician and billed under specific benefit categories (often infused/injectable drugs given in a provider setting). Whether Firdapse fits a Part B scenario depends on the route of administration and the billing setup—most patients will still rely on Part D for oral outpatient medications.
