$76,755

Medicare paid this office $76,755 for 222 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

222 Original Medicare patients in 2024. Average age 74 · Under 65 12% · 85 and older 12% · Women 56% · Also on Medicaid 36% · Health risk score 1.63. Above the middle of the specialty; the typical neurosurgery clinician is at 1.46.

Conditions among them: High blood pressure 75% · Diabetes 44% · Chronic kidney disease 36% · Coronary heart disease 27% · Heart failure 23% · Depression 23% · Stroke 22% · COPD 15% · Atrial fibrillation 14% · Cancer 12% · Dementia 12%.

The office billed $280,028, Medicare allowed $101,723 and paid $76,755; for 586 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.

$1,163 in 2024

Medicaid paid $1,163 for 12 billed services this clinician did in 2024, up to 12 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.

$1,620

Pharmacies billed $1,620 in 2024.

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

Opioids were 16% of their Part D prescriptions (22 of 137) in 2024. At or below the middle of the specialty; the typical neurosurgery clinician is at 28%. Surgeons prescribe little besides pain medicine after an operation, so their opioid share runs high.

137 generic and 0 brand-name prescriptions · $1,620 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.

$1,575 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.
