Thats the core of it; the rest of this article will break down the why, how, and whatifs in plain language.

Coverage Basics

Why is Leqembi a PartB drug?

Leqembi isnt a typical pharmacy prescription you pick up at the local drugstore. Its an IV infusion given in a clinic or hospital setting, which is why Medicare classifies it under PartB (medical insurance). PartD (prescription drug coverage) is reserved for oral meds and injectable drugs you selfadminister, so the answer to is Leqembi covered by Medicare PartD? is a clear no.

What about Medicare Advantage?

If you have a Medicare Advantage (MA) plan, youre still covered under the same PartB rules, but the plan may add its own costshare structure. Most MA plans mirror original Medicares coverage, but its worth doublechecking your plans Summary of Benefits.

Coinsurance & Deductibles Explained

In 2025 the Medicare PartB deductible is $2,025. Once thats satisfied, you owe a 20% coinsurance on the Medicareapproved amount for Leqembi. The drugs list price hovers around $30,000 per year, but Medicare negotiates a lower approved amount, which brings the outofpocket cost down to roughly $6,000 annually for most beneficiaries.

• Biomarker Confirmation: Presence of amyloid plaques shown through PET imaging or cerebrospinal fluid analysis.
• Medicare Enrollment: You must be enrolled in Original Medicare (PartA+B) or a Medicare Advantage plan that follows PartB rules.
