$47,990

Medicare paid this office $47,990 for 297 people. Most of that is long return visits and Botox.

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

Who their Medicare patients are

297 Original Medicare patients in 2024. Average age 63 · Under 65 46% · Women 74% · Also on Medicaid 48% · Health risk score 1.82. Above the middle of the specialty; the typical neurology clinician is at 1.61.

Conditions among them: High blood pressure 56% · Depression 35% · Diabetes 23% · Coronary heart disease 15% · COPD 13% · Chronic kidney disease 11% · Cancer 10% · Atrial fibrillation 10% · Dementia 10% · Stroke 10% · Heart failure 9%.

The office billed $303,216, Medicare allowed $64,857 and paid $47,990; for 842 services of 16 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.

$6,958 in 2024

Medicaid paid $6,958 for 117 billed services this clinician did in 2024, up to 20 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.

$7,684,413

Pharmacies billed $7,684,413 in 2024.

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

Opioids were 1% of their Part D prescriptions (14 of 2,214) in 2024. Above the middle of the specialty; the typical neurology clinician is at 0%.

1,588 generic and fewer than 11 brand-name prescriptions · $7,684,413 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.

$119 in 2024

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

A payment is not proof that care is biased.

Research money

Money a company paid to run a study. Where it went to their institution, the clinician is named as an investigator and did not receive it; the amount covers the whole study, often across many sites.
