Drugs they prescribed that Part D paid
$282,196

Opioids were 0% of their Part D prescriptions (0 of 849) in 2024. At or below the middle of the specialty; the typical cardiology clinician is at 0%.
707 generic and 142 brand-name prescriptions · $282,196 in drug cost.
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.
