Most PPO insurances have lap band coverage for those who have a BMI higher than 35, or weight-related medical conditions. Sometimes insurances require you to undergo a nutritional evaluation, which involves a supervised 6-12 month non-surgical weigh-loss regime. For those who are on Medicare or an HMO plan, chances are your insurance does not cover the cost of lap band. The good news is, lapband financing is available for those who do not have bariatric insurance.
