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

$16,494

Medicare paid this office $16,494 for 118 people.

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

Procedures Medicare counted

Who their Medicare patients are

118 Original Medicare patients in 2024. Average age 74 · Women 53% · Also on Medicaid 16% · Health risk score 1.29. Sicker patients than 9 in 10 peers; the typical dermatology clinician is at 1.01.

Conditions among them: High blood pressure 56% · Diabetes 25% · Cancer 25% · Coronary heart disease 23% · Chronic kidney disease 20% · Atrial fibrillation 14% · Heart failure 11% · Depression 11%.

The office billed $71,388, Medicare allowed $22,830 and paid $16,494; for 557 services of 15 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.

$289,519

Pharmacies billed $289,519 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 246) in 2024. At or below the middle of the specialty; the typical dermatology clinician is at 0%.

213 generic and 33 brand-name prescriptions · $289,519 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.

$31 in 2023

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.
