$274,111

Medicare paid this office $274,111 for 240 people.

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

Procedures Medicare counted

Who their Medicare patients are

240 Original Medicare patients in 2024. Average age 73 · Under 65 12% · 85 and older 8% · Women 56% · Also on Medicaid 26% · Health risk score 1.76. Above the middle of the specialty; the typical neurosurgery clinician is at 1.46.

Conditions among them: High blood pressure 75% · Cancer 41% · Diabetes 31% · Coronary heart disease 27% · Chronic kidney disease 27% · Stroke 26% · Depression 20% · Atrial fibrillation 16% · Heart failure 15% · Dementia 13% · COPD 11%.

The office billed $1,743,348, Medicare allowed $344,986 and paid $274,111; for 643 services of 46 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.

$371 in 2023

Medicaid paid $371 for 13 billed services this clinician did in 2023, up to 13 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.

$755

Pharmacies billed $755 in 2024.

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

Opioids were 0% of their Part D prescriptions (0 of 37) in 2024. Too few prescriptions to compare fairly with other clinicians.

37 generic and 0 brand-name prescriptions · $755 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.

$3,592 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.

Medicare did not publish checkup rates for this clinician.
