$234,758

Medicare paid this office $234,758 for 364 people.

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

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

364 Original Medicare patients in 2024. Average age 76 · Women 4% · Also on Medicaid 9% · Health risk score 1.39. At or below the middle of the specialty; the typical radiation oncology clinician is at 1.69.

Conditions among them: Cancer 75% · High blood pressure 64% · Coronary heart disease 32% · Diabetes 21% · Chronic kidney disease 20% · Atrial fibrillation 15% · Heart failure 10% · Depression 9% · COPD 7% · Stroke 7% · Dementia 4%.

The office billed $2,775,033, Medicare allowed $300,957 and paid $234,758; for 2,181 services of 37 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.

$35,979

Pharmacies billed $35,979 in 2024.

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

196 generic and 16 brand-name prescriptions · $35,979 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.

$213 in 2024

Paid work is consulting, speaking, honoraria and royalties, as opposed to meals and travel.

A payment is not proof that care is biased.

Research money

Money a company paid to run a study. Where it went to their institution, the clinician is named as an investigator and did not receive it; the amount covers the whole study, often across many sites.
