What a visit costs with Original Medicare
Typical amounts Medicare approves in ZIP 04106 (2024 Medicare rates, the latest CMS has published): a new-patient visit $129, of which you pay about $32; a follow-up visit $99, of which you pay about $25 — the 20% coinsurance after the yearly Part B deductible. Clinicians who don't accept assignment can charge up to 15% more; with a Medicare Advantage plan, your plan's copay applies instead.

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.
