263 generic and 58 brand-name prescriptions · $295,391 in drug cost · 17 antibiotic prescriptions.

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.
