Original Medicare doctor bills

$1,280

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

The office billed $20,795, Medicare allowed $1,923 and paid $1,280; for 43 services of 14 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

$568,263 in 2024

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

$156,077

Pharmacies billed $156,077 in 2024.

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

Opioids were 3% of their Part D prescriptions (38 of 1,387) in 2024. Above the middle of the specialty; the typical internal medicine clinician is at 1%.

1,170 generic and 193 brand-name prescriptions · $156,077 in drug cost · 37 antibiotic prescriptions to 27 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.
