A missing listing does not mean out of network. Directories change, and a listing does not cover every office. Call Dr. Kolly’s office at (650) 691-6174 to confirm they take your plan. Ask about the office you use, its medical group, referrals and appointments.

Medicaid work
$2,299 in 2022
Medicaid paid $2,299 for 75 billed services this clinician did in 2022, up to 14 people in a month for one service.
Medicaid and CHIP claims where this clinician did the service, fee-for-service and managed care together. Any month with fewer than 11 patients is hidden, so small Medicaid practices undercount.

Drugs they prescribed that Part D paid
$5,090
Pharmacies billed $5,090 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 3% of their Part D prescriptions (15 of 473) in 2024. At or below the middle of the specialty; the typical emergency medicine clinician is at 12%.
406 generic and fewer than 11 brand-name prescriptions · $5,090 in drug cost · 233 antibiotic prescriptions to 201 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.
