$3,341

Medicare paid this office $3,341 for 28 people.

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

Who their Medicare patients are

28 Original Medicare patients in 2024. Average age 70 · Women 57% · Health risk score 1.97. At or below the middle of the specialty; the typical emergency medicine clinician is at 2.01.

Conditions among them: High blood pressure 75% · Diabetes 50% · Coronary heart disease 46% · Heart failure 43% · Chronic kidney disease 39% · Depression 39%.

The office billed $21,121, Medicare allowed $4,411 and paid $3,341; for 29 services of 6 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.

$16,077 in 2024

Medicaid paid $16,077 for 116 billed services this clinician did in 2024, up to 19 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.

$3,181

Pharmacies billed $3,181 in 2024.

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

Opioids were 17% of their Part D prescriptions (33 of 199) in 2024. Above the middle of the specialty; the typical emergency medicine clinician is at 12%.

183 generic and fewer than 11 brand-name prescriptions · $3,181 in drug cost · 55 antibiotic prescriptions to 55 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.

$25 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.
