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 $130 follow-up here.
