Drugs they prescribed that Part D paid
$161
Pharmacies billed $161 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 87% of their Part D prescriptions (26 of 30) in 2024. Too few prescriptions to compare fairly with other clinicians.
30 generic and 0 brand-name prescriptions · $161 in drug cost.
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.
| Hydrocodone-Acetaminophen | 14 | $108 | $7 |
