$213,035

Medicare paid this office $213,035 for 141 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

141 Original Medicare patients in 2024. Average age 74 · Women 100% · Also on Medicaid 16% · Health risk score 1.80. Sicker patients than 9 in 10 peers; the typical obstetrics & gynecology clinician is at 0.88.

Conditions among them: High blood pressure 62% · Cancer 61% · Diabetes 21% · Depression 21% · Coronary heart disease 20% · Chronic kidney disease 18% · Atrial fibrillation 14% · Heart failure 11% · COPD 11%.

The office billed $1,496,255, Medicare allowed $268,825 and paid $213,035; for 6,193 services of 74 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.

$764 in 2021

Medicaid paid $764 for 12 billed services this clinician did in 2021, up to 12 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.

$1,126,807

Pharmacies billed $1,126,807 in 2024.

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

Opioids were 12% of their Part D prescriptions (37 of 318) in 2024. A higher opioid share than 9 in 10 peers; the typical obstetrics & gynecology clinician is at 0%.

239 generic and 79 brand-name prescriptions · $1,126,807 in drug cost · 44 antibiotic prescriptions to 19 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.

$206 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.

Medicare did not publish checkup rates for this clinician.
