Drugs they prescribed that Part D paid

$149,857

Pharmacies billed $149,857 in 2024.

This is pharmacy cost, not the office bill, and not what patients paid.

Opioids were 4% of their Part D prescriptions (74 of 2,102) in 2024. Above the middle of the specialty; the typical internal medicine clinician is at 1%.

1,903 generic and 188 brand-name prescriptions · $149,857 in drug cost · 49 antibiotic prescriptions to 39 people · 18 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.
