Original Medicare doctor bills

$1,179

Who their Medicare patients are

12 Original Medicare patients in 2024. Average age 79 · Under 65 0% · Health risk score 1.51. At or below the middle of the specialty; the typical emergency medicine clinician is at 2.01.

The office billed $18,747, Medicare allowed $2,046 and paid $1,179; for 20 services of 7 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
20241220791.51$18,747$1,179
20231424732.82$24,451$2,107

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

$2,326 in 2024

Medicaid paid $2,326 for 12 billed services this clinician did in 2024, up to 12 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.
