These rate the hospital, not this clinician. Most measures at most hospitals are no different from the national rate.

$46,683

Medicare paid this office $46,683 for 170 people.

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

Who their Medicare patients are

170 Original Medicare patients in 2024. Average age 76 · Women 51% · Also on Medicaid 13% · 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 69% · Depression 42% · Dementia 30% · Coronary heart disease 24% · Chronic kidney disease 22% · Diabetes 21% · Cancer 19% · Atrial fibrillation 18% · Heart failure 14% · COPD 11% · Stroke 11%.

The office billed $239,928, Medicare allowed $59,601 and paid $46,683; for 692 services of 10 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.

$328 in 2022

Medicaid paid $328 for 12 billed services this clinician did in 2022, 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.

$108,329

Pharmacies billed $108,329 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 475) in 2024. At or below the middle of the specialty; the typical neurology clinician is at 0%.

444 generic and 31 brand-name prescriptions · $108,329 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.

$1,093 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.
