$109,846

Medicare paid this office $109,846 for 155 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

155 Original Medicare patients in 2024. Average age 76 · Women 25% · Also on Medicaid 17% · Health risk score 1.26. At or below the middle of the specialty; the typical thoracic surgery clinician is at 1.74.

Conditions among them: High blood pressure 75% · Coronary heart disease 75% · Atrial fibrillation 42% · Heart failure 41% · Diabetes 38% · Chronic kidney disease 32% · Depression 21% · COPD 19% · Cancer 16% · Stroke 14%.

The office billed $151,742, Medicare allowed $138,637 and paid $109,846; for 307 services of 33 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.

$8,351

Pharmacies billed $8,351 in 2024.

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

Opioids were 16% of their Part D prescriptions (38 of 235) in 2024. Above the middle of the specialty; the typical thoracic surgery clinician is at 2%. Surgeons prescribe little besides pain medicine after an operation, so their opioid share runs high.

215 generic and 20 brand-name prescriptions · $8,351 in drug cost · 12 antibiotic prescriptions to 11 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.

$123 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.
