Original Medicare doctor bills
$976
Medicare paid this office $976 for 11 people.
This is what Medicare paid the clinician — not Medicare Advantage, and not the pharmacy.
Who their Medicare patients are
11 Original Medicare patients in 2024. Average age 66 · 85 and older 0% · Health risk score 0.77. At or below the middle of the specialty; the typical anesthesiology clinician is at 1.54.
The office billed $4,844, Medicare allowed $1,387 and paid $976; for 13 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 | 13 | 66 | 0.77 | $4,844 | $976 |
| 2019 | 11 | 19 | 60 | 1.18 | $30,532 | $2,017 |
| 2017 | 11 | 25 | 62 | 1.84 | $7,381 | $1,360 |
| 2014 | 48 | 52 | 71 | 3.41 | $66,475 | $11,327 |
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
$6 in 2024
Medicaid paid $6 for 237 billed services this clinician did in 2024, up to 15 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
$18,869
Pharmacies billed $18,869 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 12% of their Part D prescriptions (103 of 849) in 2024. Above the middle of the specialty; the typical anesthesiology clinician is at 0%.
845 generic and fewer than 11 brand-name prescriptions · $18,869 in drug cost · 11 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.
