192 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) |
|---|---|---|
| Diabetes Outpatient Self-Management Training Services, Group Session (2 Or More), Per 30 MinutesG0109 | 103 | $14 |
| Therapy Procedure for Nutrition Management, Each 15 Minutes97802 | 46 | $28 |
| Therapy Procedure Reassessment for Nutrition Management, Each 15 Minutes97803 | 43 | $25 |
Typical Medicare-allowed amounts for these services range $14–$28 (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.
