A missing listing does not mean out of network. Directories change, and a listing does not cover every office. Call Dr. Truong’s office at (408) 270-9642 to confirm they take your plan. Ask about the office you use, its medical group, referrals and appointments.

Medicaid paid $0 for 227 billed services this clinician did in 2024, up to 29 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.
