Kuvan: cost and payments to doctors
What Medicare Part D paid pharmacies for Kuvan, and the payments that named it as the associated drug or biological under the Sunshine Act for program years 2019–2025.
What Kuvan costs under Medicare Part D
This is what Part D plans and patients paid pharmacies — not what you would pay, and not money the prescriber received. Your own cost depends on your plan and where you are in your benefit year. It excludes commercial insurance, Medicaid and Part B, and it is before the manufacturer rebates CMS does not publish.

Was your doctor paid by Biomarin Pharmaceutical Inc.?
Biomarin Pharmaceutical Inc. reported the most payments naming Kuvan. Search your clinician to see whether they are among them — and what else they were paid for.
Finding a payment is not a finding of wrongdoing — most reported payments are a meal during a presentation. What matters is the kind, the size, and how it compares with their peers, which is what the profile shows.

The per-transaction average — $576 — is the number that tells you what kind of spending this is. A few dollars means meals at product presentations, reported by the thousand. Hundreds or thousands means consulting, speaking or royalty arrangements with a much smaller group of physicians. Across all 251 providers the average total is $3,117, but that average hides a very steep distribution.
