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 for Nutrition Management, Each 15 Minutes97802 | 128 | $29 |
| Therapy Procedure Reassessment for Nutrition Management, Each 15 Minutes97803 | 90 | $27 |
Typical Medicare-allowed amounts for these services range $27–$29 (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.
