Drugs they prescribed that Part D paid
$33,392
Pharmacies billed $33,392 in 2024.

335 generic and fewer than 11 brand-name prescriptions · $33,392 in drug cost · 22 antibiotic prescriptions to 17 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.

| Omeprazole | 17 | $66 | $4 |
