$140,805

Medicare paid this office $140,805 for 202 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

202 Original Medicare patients in 2024. Average age 73 · Women 100% · Also on Medicaid 12% · Health risk score 1.26. At or below the middle of the specialty; the typical gynecological oncology clinician is at 1.53.

Conditions among them: High blood pressure 57% · Cancer 41% · Diabetes 20% · Depression 19% · Chronic kidney disease 15% · Coronary heart disease 13% · Heart failure 8% · COPD 8% · Atrial fibrillation 8%.

The office billed $593,705, Medicare allowed $182,135 and paid $140,805; for 606 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.

$108,385

Pharmacies billed $108,385 in 2024.

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

Opioids were 57% of their Part D prescriptions (61 of 108) in 2024. A higher opioid share than 9 in 10 peers; the typical gynecological oncology clinician is at 13%.

98 generic and fewer than 11 brand-name prescriptions · $108,385 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.

$338,199 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.

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.
