11 Original Medicare patients in 2024. Average age 76 · Health risk score 3.23. Sicker patients than 9 in 10 peers; the typical cardiology clinician is at 1.71.

The office billed $10,940, Medicare allowed $3,097 and paid $2,467; for 19 services of 7 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.

20181220614.72$21,205$3,917

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.

Medicaid work

$26 in 2022

Medicaid paid $26 for 24 billed services this clinician did in 2022, up to 20 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

$35,809

Pharmacies billed $35,809 in 2024.

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

Opioids were 0% of their Part D prescriptions (0 of 181) in 2024. At or below the middle of the specialty; the typical cardiology clinician is at 0%.

148 generic and 33 brand-name prescriptions · $35,809 in drug cost · 14 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.
