A missing listing does not mean out of network. Directories change, and a listing does not cover every office. Call Dr. Mittal’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
$888
Pharmacies billed $888 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 12% of their Part D prescriptions (16 of 132) in 2024. At or below the middle of the specialty; the typical orthopedic surgery clinician is at 31%.
132 generic and 0 brand-name prescriptions · $888 in drug cost · 69 antibiotic prescriptions to 44 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.
