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

$43,083

Medicare paid this office $43,083 for 145 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

145 Original Medicare patients in 2024. Average age 73 · Under 65 16% · 85 and older 21% · Women 51% · Also on Medicaid 50% · Health risk score 2.11. Above the middle of the specialty; the typical general surgery clinician is at 1.69.

Conditions among them: High blood pressure 75% · Chronic kidney disease 39% · Diabetes 37% · Heart failure 34% · COPD 30% · Coronary heart disease 29% · Depression 28% · Atrial fibrillation 22% · Cancer 20% · Dementia 14% · Stroke 13%.

The office billed $195,161, Medicare allowed $54,788 and paid $43,083; for 243 services of 43 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.

$922 in 2021

Medicaid paid $922 for 31 billed services this clinician did in 2021, up to 16 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.

$1,321

Pharmacies billed $1,321 in 2024.

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

Opioids were 45% of their Part D prescriptions (13 of 29) in 2024. Too few prescriptions to judge: with under about 50 a year, a handful of patients can swing this share.

29 generic and 0 brand-name prescriptions · $1,321 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.

$27 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.
