| 2023 | 33 | 55 | 75 | 0.75 | $15,295 | $4,549 |
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
$25,181
Pharmacies billed $25,181 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
271 generic and fewer than 11 brand-name prescriptions · $25,181 in drug cost · 94 antibiotic prescriptions to 70 people.
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.
