Who their Medicare patients are

12 Original Medicare patients in 2024. Average age 37 · Under 65 100% · 85 and older 0% · Health risk score 0.63. At or below the middle of the specialty; the typical neurology clinician is at 1.61.

The office billed $18,652, Medicare allowed $6,869 and paid $4,658; for 638 services of 7 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

202412638370.63$18,652$4,658
202311325350.51$12,187$2,931
202111548330.59$15,841$4,159

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.

Medicaid work

$269 in 2023

Medicaid paid $269 for 14 billed services this clinician did in 2023, up to 14 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.

Drugs they prescribed that Part D paid

$83,084

Pharmacies billed $83,084 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 179) in 2024. At or below the middle of the specialty; the typical neurology clinician is at 0%.

143 generic and 36 brand-name prescriptions · $83,084 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.
