Leqembi Lecanemab-Irmb Same name 15 323 $418,711

Matched to this product by name; CMS does not link its files to Open Payments, so a similar name can be a different strength, form or brand. Prescriber counts include only prescribers with 11 or more claims of the drug, because CMS publishes nothing below that. Part D covers drugs dispensed to Medicare beneficiaries at a pharmacy; it does not include drugs given in a clinic or hospital, or patients with other insurance.

Two separate records. Claims come from Medicare and related payments from Open Payments. They are shown in one row because they name the same product; they do not show that a payment affected a prescription.

"No profile" means the prescriber has no Open Payments record here; "None on record" means no payment naming this product in the payment year. Related payments are general payments, and one that names several products is split evenly, so an amount is payments related to the product, not money paid for it. The list is the prescribers with the most claims, up to 100 per drug.

Given in the clinic

Part B · billing code
Medicare Part B billing codes matched to Leqembi
Billing code Providers Services Paid by Medicare
Injection, lecanemab-irmb, 1 mg J0174 254 31,382,754 $32,561,515

Drugs given by a clinician are billed to Medicare Part B, not Part D. The product is tied to a billing code through the NDC on CMS's crosswalk, which was published for a later quarter than the payments, so a code that changed in between can be missed. Providers with fewer than 11 patients for the code are not published. Medicare's payment here is what it paid for the services, to the billing practice.

What you are looking at

Manufacturers name the drug, biological or device a payment relates to. CMS does not give products their own identifiers, so a product here is assembled from how it was reported — a brand may appear under more than one spelling, and this page covers one of them rather than the brand as a whole.
