Drugs they prescribed that Part D paid
$3,121
Pharmacies billed $3,121 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 13% of their Part D prescriptions (19 of 147) in 2024. Above the middle of the specialty; the typical emergency medicine clinician is at 12%.
138 generic and fewer than 11 brand-name prescriptions · $3,121 in drug cost · 46 antibiotic prescriptions to 44 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.
