Drugs they prescribed that Part D paid
$24,306
Pharmacies billed $24,306 in 2024.

Opioids were 0% of their Part D prescriptions (0 of 442) in 2024. At or below the middle of the specialty; the typical general practice clinician is at 0%.
407 generic and 35 brand-name prescriptions · $24,306 in drug cost · 16 antibiotic prescriptions to 12 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.
