A missing listing does not mean out of network. Directories change, and a listing does not cover every office. Call Dr. Behrends’s office at (415) 476-1000 to confirm they take your plan. Ask about the office you use, its medical group, referrals and appointments.

These rate the hospital, not this clinician. Most measures at most hospitals are no different from the national rate.

Medicaid work

$1,275 in 2022

Medicaid paid $1,275 for 35 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.
