Drugs they prescribed that Part D paid

$2,805

Pharmacies billed $2,805 in 2024.

This is pharmacy cost, not the office bill, and not what patients paid.

Opioids were 15% of their Part D prescriptions (21 of 137) in 2024. Above the middle of the specialty; the typical emergency medicine clinician is at 12%.

127 generic and fewer than 11 brand-name prescriptions · $2,805 in drug cost · 44 antibiotic prescriptions to 40 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.

Largest Part D drug costs
Cephalexin13$55$4
Oxycodone13$49$4
