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 (510) 437-4800 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.

$3,790 in drug cost.

Part D prescriptions only. The opioid rate is opioid prescriptions as a share of all this clinician's Part D prescriptions; surgeons and pain specialists run higher than others, so it is shown against the same specialty.
