$92,038

Medicare paid this office $92,038 for 312 people.

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

Procedures Medicare counted

Procedures year by year

Times billed to Original Medicare each year. A blank year means fewer than 11 people had it, or none: Medicare does not publish smaller counts. Medicare Advantage patients are not included.

Who their Medicare patients are

312 Original Medicare patients in 2024. Average age 74 · Under 65 13% · 85 and older 15% · Women 51% · Also on Medicaid 47% · Health risk score 1.50. Above the middle of the specialty; the typical neurosurgery clinician is at 1.46.

Conditions among them: High blood pressure 75% · Diabetes 49% · Stroke 38% · Coronary heart disease 34% · Chronic kidney disease 29% · Atrial fibrillation 27% · Depression 27% · Heart failure 23% · COPD 21% · Dementia 15% · Cancer 13%.

The office billed $578,989, Medicare allowed $120,523 and paid $92,038; for 650 services of 30 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.

$9,516 in 2024

Medicaid paid $9,516 for 150 billed services this clinician did in 2024, up to 29 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.

$589

Pharmacies billed $589 in 2024.

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

28 generic and 0 brand-name prescriptions · $589 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.

$55 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.

9 measures · 2023

Medicare asked this office to report how often certain checkups happened in 2023. This is not a grade for the doctor. A specialist’s patients may not need every screening.
