Who their Medicare patients are
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.
Year by year
| 2024 | 11 | 19 | 76 | 3.23 | $10,940 | $2,467 |
| 2022 | 17 | 26 | 76 | 1.94 | $19,148 | $2,780 |
| 2021 | 17 | 34 | 66 | 2.90 | $72,539 | $7,199 |
| 2018 | 12 | 20 | 61 | 4.72 | $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.
| Electrocardiogram, routine ECG with at least 12 leads; interpretation and report only | 24 | $26 |
| 2022 | 24 | 1 | 20 | $26 |
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.
