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

$33,997

Medicare paid this office $33,997 for 88 people.

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

Who their Medicare patients are

88 Original Medicare patients in 2024. Average age 73 · Women 55% · Also on Medicaid 39% · Health risk score 2.73. Sicker patients than 9 in 10 peers; the typical neurology clinician is at 1.61.

Conditions among them: High blood pressure 75% · Stroke 68% · Diabetes 50% · Coronary heart disease 49% · Chronic kidney disease 48% · Atrial fibrillation 42% · Heart failure 40% · Depression 38% · Dementia 33% · COPD 27% · Cancer 22%.

The office billed $309,396, Medicare allowed $42,797 and paid $33,997; for 203 services of 3 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.

$18,847 in 2024

Medicaid paid $18,847 for 80 billed services this clinician did in 2024, up to 15 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.

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

Opioids were 0% of their 46 Part D prescriptions in 2016. Too few prescriptions to judge: with under about 50 a year, a handful of patients can swing this share.

Part D prescriptions only. A drug prescribed to fewer than 11 people in a year is hidden.

Year by year

Part D prescriptions only. A drug prescribed to fewer than 11 people in a year is hidden.

$102 in 2024

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.

Medicare did not publish checkup rates for this clinician.
