Original Medicare doctor bills
$2,761
Medicare paid this office $2,761 for 16 people.
This is what Medicare paid the clinician — not Medicare Advantage, and not the pharmacy.
Who their Medicare patients are
16 Original Medicare patients in 2024. Average age 68 · Health risk score 1.61. At or below the middle of the specialty; the typical hematology clinician is at 2.35.
The office billed $16,914, Medicare allowed $3,511 and paid $2,761; for 19 services of 5 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.
Medicaid work
$53,718 in 2024
Medicaid paid $53,718 for 347 billed services this clinician did in 2024, up to 24 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.

Drugs they prescribed that Part D paid
$587,982
Pharmacies billed $587,982 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
88 generic and 57 brand-name prescriptions · $587,982 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.
