Urgent care centers should be used instead of emergency rooms for non-emergency medical care needed after normal clinic hours for TRICARE beneficiaries. Emergency rooms are intended for true medical emergencies like heart attacks or accidents. The document provides a list of local urgent care centers that accept TRICARE patients. Using an urgent care center rather than an emergency room saves wait times and potential costs. Patients must call the after-hours nurse line to get a referral for urgent care visits.
