89 generic and 0 brand-name prescriptions · $1,482 in drug cost · 13 antibiotic prescriptions to 11 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.
