Drugs they prescribed that Part D paid
$10,684
Pharmacies billed $10,684 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 13% of their Part D prescriptions (76 of 567) in 2024. Above the middle of the specialty; the typical emergency medicine clinician is at 12%.
534 generic and 33 brand-name prescriptions · $10,684 in drug cost · 160 antibiotic prescriptions to 128 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.
