Original Medicare doctor bills
$349
Medicare paid this office $349 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 75 · Under 65 0% · Health risk score 0.72. At or below the middle of the specialty; the typical ophthalmology clinician is at 1.16.
The office billed $2,379, Medicare allowed $1,064 and paid $349; for 15 services of 6 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 | 15 | 75 | 0.72 | $2,379 | $349 |
| 2023 | 14 | 33 | 73 | 0.84 | $6,744 | $2,020 |
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.
Drugs they prescribed that Part D paid
$71,198
Pharmacies billed $71,198 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 1,466) in 2024. At or below the middle of the specialty; the typical ophthalmology clinician is at 0%.
1,123 generic and 343 brand-name prescriptions · $71,198 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.
