What this provider does (Medicare)

| Service (HCPCS) | Medicare services | Typical Medicare-allowed (2024) |
|---|---|---|
| X-Ray of Chest, 2 Views71046 | 13 | $12 |
Typical Medicare-allowed amounts for these services range $12–$12 (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.
