Drugs they prescribed that Part D paid

$9,963

Pharmacies billed $9,963 in 2024.

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

Opioids were 9% of their Part D prescriptions (17 of 186) in 2024. At or below the middle of the specialty; the typical emergency medicine clinician is at 12%.

156 generic and 30 brand-name prescriptions · $9,963 in drug cost · 33 antibiotic prescriptions to 26 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.
