Original Medicare doctor bills

$37,819

Medicare paid this office $37,819 for 248 people.

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

Largest Original Medicare bills
Emergency department visit with high level of medical decision making151$22,770$147
Critical care, first 30-74 minutes36$6,628$179
Emergency department visit with moderate level of medical decision making45$4,789$100

Who their Medicare patients are

248 Original Medicare patients in 2024. Average age 74 · Under 65 11% · 85 and older 20% · Women 52% · Also on Medicaid 58% · Health risk score 2.28. Above the middle of the specialty; the typical emergency medicine clinician is at 2.01.

The office billed $320,930, Medicare allowed $47,922 and paid $37,819; for 388 services of 28 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

$35,603 in 2024

Medicaid paid $35,603 for 353 billed services this clinician did in 2024, up to 40 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

$1,447

Pharmacies billed $1,447 in 2024.

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

95 generic and fewer than 11 brand-name prescriptions · $1,447 in drug cost · 39 antibiotic prescriptions to 32 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.
