Original Medicare doctor bills

$1,250

Medicare paid this office $1,250 for 13 people.

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

Who their Medicare patients are

13 Original Medicare patients in 2024. Average age 71 · Health risk score 1.81. At or below the middle of the specialty; the typical emergency medicine clinician is at 2.01.

The office billed $9,033, Medicare allowed $1,960 and paid $1,250; for 15 services of 6 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.

20141112752.00$5,556$1,108

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

$1,442 in 2024

Medicaid paid $1,442 for 17 billed services this clinician did in 2024, up to 17 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

$4,732

Pharmacies billed $4,732 in 2024.

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

208 generic and fewer than 11 brand-name prescriptions · $4,732 in drug cost · 51 antibiotic prescriptions to 49 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.
