$106,062

Medicare paid this office $106,062 for 191 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

191 Original Medicare patients in 2024. Average age 73 · Women 56% · Also on Medicaid 27% · Health risk score 1.73. At or below the middle of the specialty; the typical thoracic surgery clinician is at 1.74.

Conditions among them: High blood pressure 75% · Cancer 53% · Coronary heart disease 37% · COPD 32% · Atrial fibrillation 31% · Depression 29% · Diabetes 27% · Heart failure 26% · Chronic kidney disease 24% · Stroke 9%.

The office billed $503,399, Medicare allowed $133,308 and paid $106,062; for 358 services of 73 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.

$835

Pharmacies billed $835 in 2024.

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

Opioids were 57% of their Part D prescriptions (17 of 30) in 2024. Too few prescriptions to judge: with under about 50 a year, a handful of patients can swing this share.

29 generic and fewer than 11 brand-name prescriptions · $835 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.

$83 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.
