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

| Automated Urinalysis Test81003 | 21 | $2 |
Typical Medicare-allowed amounts for these services range $2–$4 (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.
