A missing listing does not mean out of network. Directories change, and a listing does not cover every office. Call Charlotte Dimaya’s office at (408) 885-5000 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
$6,066
Pharmacies billed $6,066 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 108) in 2024. At or below the middle of the specialty; the typical nurse practitioner clinician is at 0%.
85 generic and fewer than 11 brand-name prescriptions · $6,066 in drug cost · 26 antibiotic prescriptions to 16 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.
