Drugs they prescribed that Part D paid
$56,382
Pharmacies billed $56,382 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 1% of their Part D prescriptions (15 of 1,040) in 2024. At or below the middle of the specialty; the typical family practice clinician is at 2%.
926 generic and fewer than 11 brand-name prescriptions · $56,382 in drug cost · 15 antibiotic prescriptions · 14 antipsychotic prescriptions to people over 65.
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.
