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

$427,284

Medicare paid this office $427,284 for 940 people. Most of that is long return visits and Botox.

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

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

940 Original Medicare patients in 2024. Average age 75 · Under 65 10% · 85 and older 16% · Women 55% · Also on Medicaid 30% · Health risk score 1.65. Above the middle of the specialty; the typical neurology clinician is at 1.61.

Conditions among them: High blood pressure 69% · Depression 33% · Chronic kidney disease 28% · Stroke 28% · Diabetes 26% · Dementia 24% · Coronary heart disease 22% · Atrial fibrillation 21% · Heart failure 17% · Cancer 16% · COPD 13%.

The office billed $1,513,029, Medicare allowed $563,817 and paid $427,284; for 47,411 services of 37 kinds; $220,784 of it was for drugs given in the office and $206,500 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.

$98,009 in 2024

Medicaid paid $98,009 for 173 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.

$2,810,374

Pharmacies billed $2,810,374 in 2024.

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

Opioids were 0% of their Part D prescriptions (29 of 7,100) in 2024. Above the middle of the specialty; the typical neurology clinician is at 0%.

5,989 generic and fewer than 11 brand-name prescriptions · $2,810,374 in drug cost · 11 antibiotic prescriptions · 288 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.
