Drugs they prescribed that Part D paid
$2,875
Pharmacies billed $2,875 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 11% of their Part D prescriptions (20 of 185) in 2024. At or below the middle of the specialty; the typical emergency medicine clinician is at 12%.
182 generic and fewer than 11 brand-name prescriptions · $2,875 in drug cost · 25 antibiotic prescriptions to 21 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.
