What this provider does (Medicare)

Based on Medicare fee-for-service claims, 2024; not all care is captured.

New Patient Office Or Other Outpatient Visit With Low Level of Medical Decision Making, If Using Time, 30 Minutes Or More99203	26	$103
Detection Test By Immunoassay With Direct Visual Observation for Severe Acute Respiratory Syndrome Coronavirus 2 (covid-19)87811	11	$41

Typical Medicare-allowed amounts for these services range $41–$103 (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.
