Year by year

| 2023 | 11 | 13 | 72 | 1.29 | $72,236 | $4,203 |

Drugs they prescribed that Part D paid
$6,424
Pharmacies billed $6,424 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
12 generic and fewer than 11 brand-name prescriptions · $6,424 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.
