$3,049

146 generic and 13 brand-name prescriptions · $3,049 in drug cost · 25 antibiotic prescriptions to 18 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.
