Blue Cross Blue Shield Massachusetts does offer coverage for weight loss programs, but this can vary depending on individual plans and policy details. Some plans may provide coverage for medically-supervised weight loss programs if they are deemed medically necessary due to obesity-related health issues. Other plans may offer discounts or reimbursements for participating in certain weight loss programs or services. To determine what weight loss programs are covered under your specific Blue Cross Blue Shield plan, it is best to contact their customer service or review the policy documents provided by your employer.
