The office billed $312,310, Medicare allowed $68,256 and paid $54,084; for 632 services of 13 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.

Medicaid work

$6,297 in 2024

Medicaid paid $6,297 for 76 billed services this clinician did in 2024, up to 20 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.

Pharmacies billed $13,475 in 2024.

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

191 generic and 21 brand-name prescriptions · $13,475 in drug cost · 33 antibiotic prescriptions to 26 people.

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.
