In Los Angeles, insurance coverage for weight loss surgery varies by provider, plan type, and specific patient qualifications. Many major health insurance providers offer coverage for bariatric procedures, such as gastric sleeve and gastric bypass surgery, provided certain medical criteria are met. Typically, you must demonstrate medical necessity, including a BMI of 40 or higher, or a BMI of 35 or higher with obesity-related health conditions such as diabetes, hypertension, or sleep apnea. Insurers usually require documentation of previous attempts at non-surgical weight loss, including medically supervised diets. To confirm coverage, it's advisable to contact your insurance company directly or consult with a bariatric surgeon’s office, which often assists patients in verifying benefits and obtaining necessary approvals.
