A missing listing does not mean out of network. Directories change, and a listing does not cover every office. Call Dr. Tanaka’s office at (408) 279-8080 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
$90
Pharmacies billed $90 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 0% of their Part D prescriptions (0 of 12) in 2024. Too few prescriptions to judge: with under about 50 a year, a handful of patients can swing this share.
12 generic and 0 brand-name prescriptions · $90 in drug cost · 12 antibiotic prescriptions.
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.
