Drugs they prescribed that Part D paid
$3,795
Pharmacies billed $3,795 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 6% of their Part D prescriptions (14 of 226) in 2024. At or below the middle of the specialty; the typical emergency medicine clinician is at 12%.
205 generic and 21 brand-name prescriptions · $3,795 in drug cost · 61 antibiotic prescriptions to 53 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.
