Drugs they prescribed that Part D paid

$8,258

Pharmacies billed $8,258 in 2024.

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

Opioids were 16% of their Part D prescriptions (34 of 208) in 2024. Above the middle of the specialty; the typical emergency medicine clinician is at 12%.

192 generic and fewer than 11 brand-name prescriptions · $8,258 in drug cost · 56 antibiotic prescriptions to 49 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.
