$23,128

Medicare paid this office $23,128 for 90 people.

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

Who their Medicare patients are

90 Original Medicare patients in 2024. Average age 72 · Women 49% · Also on Medicaid 41% · Health risk score 1.65. At or below the middle of the specialty; the typical general surgery clinician is at 1.69.

Conditions among them: High blood pressure 75% · Diabetes 47% · Depression 36% · Coronary heart disease 32% · Chronic kidney disease 29% · COPD 28% · Heart failure 27% · Atrial fibrillation 26% · Dementia 18% · Cancer 17%.

The office billed $102,633, Medicare allowed $30,183 and paid $23,128; for 153 services of 43 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.

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.

$1,730 in 2023

Medicaid paid $1,730 for 14 billed services this clinician did in 2023, up to 14 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.

$523

Pharmacies billed $523 in 2024.

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

Opioids were 67% of their Part D prescriptions (16 of 24) in 2024. Too few prescriptions to compare fairly with other clinicians.

22 generic and fewer than 11 brand-name prescriptions · $523 in drug cost.

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.

$3,066 in 2025

Paid work is consulting, speaking, honoraria and royalties, as opposed to meals and travel.

A payment is not proof that care is biased.
