$28,667

Medicare paid this office $28,667 for 104 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

104 Original Medicare patients in 2024. Average age 69 · Women 61% · Also on Medicaid 21% · Health risk score 1.47. At or below the middle of the specialty; the typical neurology clinician is at 1.61.

Conditions among them: High blood pressure 68% · Depression 37% · Diabetes 31% · Stroke 24% · Chronic kidney disease 15% · Cancer 15% · Atrial fibrillation 15% · Coronary heart disease 14% · Heart failure 12%.

The office billed $133,387, Medicare allowed $39,340 and paid $28,667; for 313 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.

$8,944 in 2023

Medicaid paid $8,944 for 55 billed services this clinician did in 2023, 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.

$289,439

Pharmacies billed $289,439 in 2024.

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

319 generic and 93 brand-name prescriptions · $289,439 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.

$73 in 2025

A payment is not proof that care is biased.

Medicare did not publish checkup rates for this clinician.
