A missing listing does not mean out of network. Directories change, and a listing does not cover every office. Call Dr. Wan’s office at (650) 396-8110 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.

Opioids were 0% of their 33 Part D prescriptions in 2020. Too few prescriptions to judge: with under about 50 a year, a handful of patients can swing this share.

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

A payment is not proof that care is biased.
