Original Medicare doctor bills

$2,769

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

Largest Original Medicare bills
Emergency department visit with moderate level of medical decision making22$1,798$82

The office billed $20,372, Medicare allowed $4,298 and paid $2,769; for 30 services of 5 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

$22,882 in 2024

Medicaid paid $22,882 for 209 billed services this clinician did in 2024, up to 32 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

$6,492

Pharmacies billed $6,492 in 2024.

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

Opioids were 5% of their Part D prescriptions (13 of 246) in 2024. At or below the middle of the specialty; the typical emergency medicine clinician is at 12%.

225 generic and 21 brand-name prescriptions · $6,492 in drug cost · 50 antibiotic prescriptions to 46 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.
