$188,623

Medicare paid this office $188,623 for 422 people.

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

The office billed $370,795, Medicare allowed $235,190 and paid $188,623; for 2,461 services of 19 kinds; $31,195 of it was for drugs given in the office and $157,428 for care.

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 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.

$51,718 in 2024

Medicaid paid $51,718 for 1,327 billed services this clinician did in 2024, up to 101 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.

$1,636,516

Pharmacies billed $1,636,516 in 2024.

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

Opioids were 0% of their Part D prescriptions (30 of 20,545) in 2024. At or below the middle of the specialty; the typical internal medicine clinician is at 1%.

18,509 generic and 1,909 brand-name prescriptions · $1,636,516 in drug cost · 342 antibiotic prescriptions to 255 people · 43 antipsychotic prescriptions to people over 65.

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.

Year by year

Part D prescriptions only. A drug prescribed to fewer than 11 people in a year is hidden.
