Drugs they prescribed that Part D paid
$2,366
Pharmacies billed $2,366 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
66 generic and fewer than 11 brand-name prescriptions · $2,366 in drug cost · 50 antibiotic prescriptions to 19 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.
| Doxycycline Hyclate | 19 | $206 | $11 |
| Cephalexin | 18 | $125 | $7 |
