A missing listing does not mean out of network. Directories change, and a listing does not cover every office. Call Dr. Chang’s office at (408) 284-0140 to confirm they take your plan. Ask about the office you use, its medical group, referrals and appointments.

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.
