173 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) |
|---|---|---|
| Therapy Procedure Using Functional Activities97530 | 77 | $32 |
| Therapy Procedure to Re-Educate Brain-To-Nerve-To-Muscle Function, Each 15 Minutes97112 | 43 | $26 |
| Therapy Procedure Using Manual Technique, Each 15 Minutes97140 | 40 | $21 |
| Evaluation for Physical Therapy, Typically 20 Minutes97161 | 13 | $101 |
Typical Medicare-allowed amounts for these services range $21–$101 (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.
