|---|---|---|
| Psychotherapy, 1 Hour90837 | 133 | $149 |
Typical Medicare-allowed amounts for these services range $149–$149 (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.
