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

$8,070

Medicare paid this office $8,070 for 37 people.

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

Who their Medicare patients are

37 Original Medicare patients in 2024. Average age 69 · Women 70% · Also on Medicaid 43% · Health risk score 1.61. Above the middle of the specialty; the typical maxillofacial surgery clinician is at 1.25.

Conditions among them: High blood pressure 73% · Chronic kidney disease 32% · Cancer 30%.

The office billed $78,433, Medicare allowed $10,125 and paid $8,070; for 56 services of 18 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.

$361,151 in 2024

Medicaid paid $361,151 for 4,717 billed services this clinician did in 2024, up to 128 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.

$1,624

Pharmacies billed $1,624 in 2024.

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

Opioids were 7% of their Part D prescriptions (31 of 438) in 2024. At or below the middle of the specialty; the typical maxillofacial surgery clinician is at 23%. Surgeons prescribe little besides pain medicine after an operation, so their opioid share runs high.

436 generic and fewer than 11 brand-name prescriptions · $1,624 in drug cost · 197 antibiotic prescriptions to 165 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.

$637 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.
