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) |
|---|---|---|
| Drug Test(s), Definitive, Utilizing (1) Drug Identification Methods Able to Identify Individual Drugs and Distinguish Between Structural Isomers (but Not Necessarily Stereoisomers), Including, But Not Limited to Gc/Ms (any Type, Single Or Tandem) and Lc/MsG0481 | 103 | $122 |
Typical Medicare-allowed amounts for these services range $122–$122 (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.
