A missing listing does not mean out of network. Directories change, and a listing does not cover every office. Call Dr. Muldowney’s office at (510) 841-0411 to confirm they take your plan. Ask about the office you use, its medical group, referrals and appointments.

Medicaid work

$379 in 2024

Medicaid paid $379 for 44 billed services this clinician did in 2024, up to 14 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

$65,592

Pharmacies billed $65,592 in 2024.

This is pharmacy cost, not the office bill, and not what patients paid.

Opioids were 2% of their Part D prescriptions (13 of 779) in 2024. Above the middle of the specialty; the typical internal medicine clinician is at 1%.

694 generic and fewer than 11 brand-name prescriptions · $65,592 in drug cost · 84 antibiotic prescriptions to 78 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.
