197 Medicare services, 2024 (ranked within specialty)
Medicare volume is ranked against active providers in the same specialty. Signals a provider has no public data for (e.g. Medicare claims) are left out of the score entirely — never counted as zero — so providers without that data are not penalized. See the full formula and weights in our methodology.
What this provider does (Medicare)
Based on Medicare fee-for-service claims, 2024; not all care is captured.
| Service (HCPCS) | Medicare services | Typical Medicare-allowed (2024) |
|---|---|---|
| Anesthesia for Procedure to Correct Abnormal Heart Rhythm00410 | 76 | $98 |
| Ultrasound of Heart With Probe in Esophagus, With Report93312 | 50 | $100 |
| Ultrasound of Heart With Color-Depicted Blood Flow, Rate and Valve Function93325 | 50 | $3 |
| Insertion of Artery Tube for Blood Sampling Or Infusion Through Skin36620 | 21 | $42 |
Typical Medicare-allowed amounts for these services range $3–$100 (2024). The Medicare-allowed amount is what Medicare recognizes for a service under fee-for-service — a reference figure for 2024, not a price quote and not what you would be billed. Medicare Part B covers roughly an eighth of all NPIs (65+ skew); services with fewer than 11 beneficiaries are suppressed by CMS.
