Medicaid work
$526 in 2021
Medicaid paid $526 for 96 billed services this clinician did in 2021, up to 26 people in a month for one service.
Medicaid and CHIP claims where this clinician did the service, fee-for-service and managed care together. Any month with fewer than 11 patients is hidden, so small Medicaid practices undercount.
| OFFICE/OUTPATIENT NEW SF MDM 15 MINUTES | 31 | $314 |
| Short return visit | 65 | $212 |
| 2021 | 96 | 2 | 26 | $526 |
Drugs they prescribed that Part D paid
$574
Pharmacies billed $574 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
36 generic and fewer than 11 brand-name prescriptions · $574 in drug cost · 12 antibiotic prescriptions to 12 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.
