A missing listing does not mean out of network. Directories change, and a listing does not cover every office. Call Dr. Cheng’s office at (415) 476-1000 to confirm they take your plan. Ask about the office you use, its medical group, referrals and appointments.

Original Medicare doctor bills

$61,285

Medicare paid this office $61,285 for 112 people. Most of that is long return visits and Botox.

This is what Medicare paid the clinician — not Medicare Advantage, and not the pharmacy.

Medicaid work

$4,212 in 2023

Medicaid paid $4,212 for 27 billed services this clinician did in 2023, up to 13 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

$45,066

Pharmacies billed $45,066 in 2024.

This is pharmacy cost, not the office bill, and not what patients paid.

Opioids were 49% of their Part D prescriptions (321 of 653) in 2024. A higher opioid share than 9 in 10 peers; the typical family practice clinician is at 2%. Long-acting opioids: 53% of their opioid prescriptions.

623 generic and 30 brand-name prescriptions · $45,066 in drug cost.

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.
