These rate the hospital, not this clinician. Most measures at most hospitals are no different from the national rate.

$140,537

Medicare paid this office $140,537 for 138 people. Most of that is long return visits and Botox.

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

138 Original Medicare patients in 2024. Average age 73 · Women 45% · Also on Medicaid 16% · Health risk score 2.75. Above the middle of the specialty; the typical hematology-oncology clinician is at 2.04.

Conditions among them: High blood pressure 69% · Chronic kidney disease 41% · Diabetes 22% · Heart failure 20% · Coronary heart disease 17% · Atrial fibrillation 17% · Depression 17% · Cancer 13% · COPD 9%.

The office billed $1,179,345, Medicare allowed $180,699 and paid $140,537; for 2,773 services of 28 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.

$6,830 in 2024

Medicaid paid $6,830 for 34 billed services this clinician did in 2024, up to 14 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.

$2,105,534

Pharmacies billed $2,105,534 in 2024.

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

135 generic and 101 brand-name prescriptions · $2,105,534 in drug cost · 17 antibiotic prescriptions.

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.

$88,908 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.
