Medicaid work
$23,374 in 2024
Medicaid paid $23,374 for 156 billed services this clinician did in 2024, up to 19 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.
| Clinic visit/encounter, all-inclusive | 48 | $16,038 |
| Short return visit (20+ min) | 31 | $4,074 |

Drugs they prescribed that Part D paid
$486
Pharmacies billed $486 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 0% of their Part D prescriptions (0 of 18) in 2024. Too few prescriptions to judge: with under about 50 a year, a handful of patients can swing this share.
16 generic and fewer than 11 brand-name prescriptions · $486 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.
