Procedures Medicare counted

Who their Medicare patients are

124 Original Medicare patients in 2024. Average age 75 · Women 64% · Also on Medicaid 29% · Health risk score 1.24. At or below the middle of the specialty; the typical physician assistant clinician is at 1.31.

Conditions among them: High blood pressure 75% · Diabetes 27% · Coronary heart disease 27% · Depression 23% · Atrial fibrillation 21% · Chronic kidney disease 19% · Cancer 18% · Heart failure 17% · Dementia 10% · COPD 9%.

The office billed $142,557, Medicare allowed $17,008 and paid $12,413; for 216 services of 11 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.

$14,266

Pharmacies billed $14,266 in 2024.

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

Opioids were 23% of their Part D prescriptions (129 of 563) in 2024. Above the middle of the specialty; the typical physician assistant clinician is at 1%.

557 generic and fewer than 11 brand-name prescriptions · $14,266 in drug cost · 124 antibiotic prescriptions to 71 people.

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.

$266 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.
