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

| Psychotherapy, 30 Minutes90832 | 335 | $60 |
| Psychiatric Diagnostic Evaluation90791 | 34 | $129 |
Typical Medicare-allowed amounts for these services range $60–$129 (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.
