Drugs they prescribed that Part D paid

$78,823

Opioids were 2% of their Part D prescriptions (23 of 952) in 2024. Above the middle of the specialty; the typical family practice clinician is at 2%.

792 generic and 143 brand-name prescriptions · $78,823 in drug cost · 58 antibiotic prescriptions to 51 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.
