This is what Medicare paid the clinician — not Medicare Advantage, and not the pharmacy.

The office billed $400,950, Medicare allowed $122,936 and paid $96,557; for 921 services of 10 kinds.

Original Medicare patients only. A risk score of 1.0 is the average Medicare patient; higher means sicker. Any count under 11 is hidden.

Year by year

Original Medicare only. A service billed for fewer than 11 people in a year is hidden, so the lines can add up to less than the year's total.

$14,612 in 2024

Medicaid paid $14,612 for 495 billed services this clinician did in 2024, up to 19 people in a month for one service.

Medicaid and CHIP claims where this clinician did the service, fee-for-service and managed care together. Any month with fewer than 11 patients is hidden, so small Medicaid practices undercount.

$19,678

Pharmacies billed $19,678 in 2024.

This is pharmacy cost, not the office bill, and not what patients paid.

74 generic and fewer than 11 brand-name prescriptions · $19,678 in drug cost.

Part D prescriptions only. The opioid rate is opioid prescriptions as a share of all this clinician's Part D prescriptions; surgeons and pain specialists run higher than others, so it is shown against the same specialty.

Year by year

Part D prescriptions only. A drug prescribed to fewer than 11 people in a year is hidden.
