Drugs they prescribed that Part D paid
$1,421
Pharmacies billed $1,421 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 33% of their Part D prescriptions (16 of 48) in 2024. Too few prescriptions to judge: with under about 50 a year, a handful of patients can swing this share.
47 generic and fewer than 11 brand-name prescriptions · $1,421 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.
