PPO & Medicare welcome
Our board-certified gastroenterologists are in network with most PPO plans, including Aetna, Anthem Blue Cross, Blue Shield of California, Cigna, and UnitedHealthcare, plus Medicare. Most PPO plans need no referral, and healthy adults 45 and older can often schedule a screening colonoscopy without an office visit.
