2,620 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) |
|---|---|---|
| Cell Examination of Specimen, Selective Cellular Enhancement Technique88112 | 2,082 | $37 |
| Screening Cytopathology, Cervical Or Vaginal (any Reporting System), Collected in Preservative Fluid, Automated Thin Layer Preparation, Requiring Interpretation By PhysicianG0124 | 421 | $26 |
| Pap Test88141 | 117 | $26 |
Typical Medicare-allowed amounts for these services range $26–$37 (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.
