2 hospitals

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

$34,679

Medicare paid this office $34,679 for 52 people.

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

Procedures Medicare counted

Who their Medicare patients are

52 Original Medicare patients in 2024. Average age 72 · Under 65 21% · 85 and older 25% · Women 40% · Also on Medicaid 77% · Health risk score 3.91. Sicker patients than 9 in 10 peers; the typical emergency medicine clinician is at 2.01.

Conditions among them: High blood pressure 75% · Diabetes 58% · Chronic kidney disease 42% · Depression 38% · Heart failure 33% · Dementia 33% · Coronary heart disease 31% · Atrial fibrillation 29% · Stroke 23%.

The office billed $96,491, Medicare allowed $43,581 and paid $34,679; for 323 services of 10 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.

$2,781 in 2024

Medicaid paid $2,781 for 429 billed services this clinician did in 2024, up to 23 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.

$1,202

Pharmacies billed $1,202 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 97) in 2024. At or below the middle of the specialty; the typical emergency medicine clinician is at 12%.

95 generic and fewer than 11 brand-name prescriptions · $1,202 in drug cost · 29 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.

$35 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.
