112 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.

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) |
|---|---|---|
| Detection Test By Immunoassay Technique for Severe Acute Respiratory Syndrome Coronavirus and Influenza87428 | 60 | $69 |
| Automated Urinalysis Test81003 | 30 | $2 |
| Detection Test By Immunoassay With Direct Visual Observation for Streptococcus, Group a (strep)87880 | 22 | $16 |
Typical Medicare-allowed amounts for these services range $2–$69 (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.
