Medicaid work
$1,430 in 2022
Medicaid paid $1,430 for 12 billed services this clinician did in 2022, up to 12 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.
| Infectious disease (viral respiratory tract infection), pathogen-specific RNA, 4 targets (severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2], influenza A, influenza B, respiratory syncytial virus [RSV]), upper respiratory specimen, each pathogen reported as detected or not detected | 12 | $1,430 |

Drugs they prescribed that Part D paid
$19,740
Pharmacies billed $19,740 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
465 generic and fewer than 11 brand-name prescriptions · $19,740 in drug cost · 20 antibiotic prescriptions to 19 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.
