Usually $0: in-network preventive visits are covered in full. Add-ons or a problem discussed during the visit are billed separately.
Coinsurance is shown at 20%, the most common in-network share; yours may be 10–40%. Primary care copays typically run $20–$50. Out-of-network or non-UnitedHealthcare plans will differ.
Not every visit needs an office. The Momentary app is AI primary care with real doctors, $19.99 a month for unlimited visits, prescriptions, lab orders and referrals; less than one $150 follow-up here.

- Does Dr. Liu accept UnitedHealthcare?
- These rates were published in UnitedHealthcare's in-network price transparency file in February 2026, which indicates Dr. Liu was in at least one UnitedHealthcare network at that time. Networks change and vary by plan, so confirm with the office at (707) 933-0500 before booking.
