$352,414

Medicare paid this office $352,414 for 747 people.

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

Who their Medicare patients are

747 Original Medicare patients in 2024. Average age 77 · Under 65 3% · 85 and older 17% · Women 57% · Also on Medicaid 4% · Health risk score 1.36. At or below the middle of the specialty; the typical neurology clinician is at 1.61.

Conditions among them: High blood pressure 75% · Coronary heart disease 32% · Diabetes 30% · Depression 27% · Dementia 27% · Stroke 24% · Atrial fibrillation 20% · Chronic kidney disease 18% · Cancer 17% · Heart failure 15% · COPD 13%.

The office billed $1,216,642, Medicare allowed $461,277 and paid $352,414; for 34,102 services of 32 kinds; $153,956 of it was for drugs given in the office and $198,458 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.

$28,761 in 2023

Medicaid paid $28,761 for 316 billed services this clinician did in 2023, up to 55 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.

$2,088,189

Pharmacies billed $2,088,189 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 4,221) in 2024. At or below the middle of the specialty; the typical neurology clinician is at 0%.

3,920 generic and fewer than 11 brand-name prescriptions · $2,088,189 in drug cost · 214 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.

$4,511 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.
