202353237730.80$16,068$3,945

Original Medicare only. A service billed for fewer than 11 people in a year is hidden, so the lines can add up to less than the year's total.

Medicaid work

$20,009 in 2021

Medicaid paid $20,009 for 118 billed services this clinician did in 2021, up to 43 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.

Drugs they prescribed that Part D paid

$59,920

Pharmacies billed $59,920 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 149) in 2024. At or below the middle of the specialty; the typical allergy/ immunology clinician is at 0%.

106 generic and 43 brand-name prescriptions · $59,920 in drug cost · 13 antibiotic prescriptions.

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.
