About This Location

Urgent Care | Kaiser Permanente Ontario Medical Center is part of Kaiser Permanente — the largest managed care organization in the US, founded in 1945 and serving 12.7M+ members across 8 states (California, Colorado, Georgia, Hawaii, Maryland, Oregon, Virginia, Washington) plus the District of Columbia. Kaiser's distinctive integrated model combines health insurance (Kaiser Foundation Health Plan), hospitals (Kaiser Foundation Hospitals — 39 medical centers), medical groups (Permanente Medical Groups with 23,000+ physicians), and pharmacies under one cohesive system. This integration enables coordinated care, lower per-member costs, and seamless EMR continuity. Urgent care is available at most Kaiser medical centers and stand-alone urgent care locations for Kaiser members (walk-in priority, no claim forms) and non-members on limited same-day basis. Services include on-site X-ray and labs, IV fluids, laceration repair, acute illness and injury treatment, and direct same-day specialist referrals via the integrated system. All visits sync to Kaiser's HealthConnect EMR (Epic-based) with full member access through kp.org and the Kaiser app for messaging, records, and 24/7 nurse advice line.
