Before you book
This list comes from Medicare's enrollment records, not from reviews. Call the office to confirm the clinician is taking new Medicare patients. With Original Medicare, a clinician who accepts assignment can only charge you the Medicare deductible and coinsurance; one who doesn't may charge up to 15% more than the Medicare-approved amount. If you have a Medicare Advantage plan, check that the clinician is in the plan's network.
The MIPS final score (0–100) comes from Medicare's Merit-based Incentive Payment System for 2024. It combines quality measures, cost, improvement activities and use of certified health records, and it sets a payment adjustment. Clinicians who report as a group share the group's score. It is not a patient rating, and many clinicians have no published score.
Payments from drug and medical device companies come from CMS Open Payments (2025 general payments: meals, travel, consulting and speaking fees, gifts and similar), summed for each clinician. Receiving payments is legal and common and does not mean a clinician did anything wrong.
