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

$70,634

Medicare paid this office $70,634 for 210 people.

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

Procedures Medicare counted

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

210 Original Medicare patients in 2024. Average age 74 · Under 65 6% · 85 and older 6% · Women 63% · Also on Medicaid 11% · Health risk score 0.99. At or below the middle of the specialty; the typical dermatology clinician is at 1.01.

Conditions among them: High blood pressure 56% · Cancer 20% · Coronary heart disease 18% · Depression 17% · Diabetes 14% · Chronic kidney disease 14% · Atrial fibrillation 11% · Heart failure 6% · COPD 6%.

The office billed $442,603, Medicare allowed $96,272 and paid $70,634; for 1,332 services of 28 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.

$508,398 in 2024

Medicaid paid $508,398 for 3,378 billed services this clinician did in 2024, up to 119 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.

$2,954,961

Pharmacies billed $2,954,961 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 1,555) in 2024. At or below the middle of the specialty; the typical dermatology clinician is at 0%.

1,128 generic and fewer than 11 brand-name prescriptions · $2,954,961 in drug cost · 55 antibiotic prescriptions to 19 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.

$74 in 2025

A payment is not proof that care is biased.

Medicare did not publish checkup rates for this clinician.
