A missing listing does not mean out of network. Directories change, and a listing does not cover every office. Call Dr. Zhong’s office at (650) 691-6174 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
$97,136
Pharmacies billed $97,136 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
1,068 generic and fewer than 11 brand-name prescriptions · $97,136 in drug cost · 36 antibiotic prescriptions to 31 people.
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.
