A missing listing does not mean out of network. Directories change, and a listing does not cover every office. Call Dr. Wang’s office at (650) 723-4000 to confirm they take your plan. Ask about the office you use, its medical group, referrals and appointments.

Drugs they prescribed that Part D paid
This is pharmacy cost, not the office bill, and not what patients paid.

Part D prescriptions only. A drug prescribed to fewer than 11 people in a year is hidden.
