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) |
|---|---|---|
| Complete Ultrasound Scan of 1 Breast76641 | 12 | $86 |
| Screening Mammography77067 | 12 | $107 |
| Diagnostic Mammography of Both Breasts77066 | 11 | $140 |
Typical Medicare-allowed amounts for these services range $86–$140 (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.
