What this provider does (Medicare)
Based on Medicare fee-for-service claims, 2024; not all care is captured.

|---|---|---|
| Evaluation for Wheelchair, Each 15 Minutes97542 | 212 | $22 |
| Evaluation for Occupational Therapy, Typically 45 Minutes97166 | 50 | $92 |
Typical Medicare-allowed amounts for these services range $22–$92 (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.
