Note that if you're on the Regular Plan health insurance option, there is no separate "in-network" and "out-of-network" reimbursement rate. It pays 80% (you pay 20%) up to their allowable maximum for a covered service, no matter what doctor you see. While staying within the UHC system will simplify billing, you can see any doctor you want, and if they can't bill UHC directly for their portion, you can submit for reimbursement.
