Original Medicare doctor bills

Who their Medicare patients are

12 Original Medicare patients in 2024. Average age 75 · Under 65 0% · Women 100% · Health risk score 0.67. At or below the middle of the specialty; the typical obstetrics & gynecology clinician is at 0.88.

The office billed $122,956, Medicare allowed $9,334 and paid $7,399; for 25 services of 15 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 by year
20241225750.67$122,956$7,399
20192127681.10$35,713$4,020

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

$247,742 in 2024

Medicaid paid $247,742 for 4,230 billed services this clinician did in 2024, up to 71 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

Pharmacies billed $97,291 in 2024.

128 generic and 151 brand-name prescriptions · $97,291 in drug cost · 20 antibiotic prescriptions to 15 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.
