The office billed $90,537, Medicare allowed $24,333 and paid $18,667; for 200 services of 31 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.

| 2023 | 74 | 102 | 73 | 1.87 | $37,196 | $7,861 |
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.

Medicaid work
$2,317 in 2024
Medicaid paid $2,317 for 89 billed services this clinician did in 2024, up to 15 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.

Drugs they prescribed that Part D paid
$2,762

This is pharmacy cost, not the office bill, and not what patients paid.
76 generic and fewer than 11 brand-name prescriptions · $2,762 in drug cost · 41 antibiotic prescriptions to 36 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.
