$7,782,866

Medicare paid this office $7,782,866 for 1,041 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

1,041 Original Medicare patients in 2024. Average age 75 · Under 65 6% · 85 and older 17% · Women 63% · Also on Medicaid 79% · Health risk score 2.41. Above the middle of the specialty; the typical hematology-oncology clinician is at 2.04.

Conditions among them: High blood pressure 75% · Coronary heart disease 58% · Diabetes 56% · Cancer 48% · Depression 43% · Chronic kidney disease 42% · Heart failure 39% · COPD 27% · Atrial fibrillation 24% · Dementia 23% · Stroke 15%.

The office billed $28,406,756, Medicare allowed $9,787,655 and paid $7,782,866; for 285,154 services of 122 kinds; $6,887,431 of it was for drugs given in the office and $895,435 for care.

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.

$73,454 in 2024

Medicaid paid $73,454 for 8,633 billed services this clinician did in 2024, up to 153 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.

$15,643,281

Pharmacies billed $15,643,281 in 2024.

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

Opioids were 2% of their Part D prescriptions (51 of 3,271) in 2024. At or below the middle of the specialty; the typical hematology-oncology clinician is at 5%. Long-acting opioids: 26% of their opioid prescriptions.

1,465 generic and 1,806 brand-name prescriptions · $15,643,281 in drug cost · 55 antibiotic prescriptions to 31 people · 22 antipsychotic prescriptions to people over 65.

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.
