Blue Cross Blue Shield of Michigan generally does not cover treatments and situations that are considered non-medical in nature, experimental or investigational, or not considered standard medical practices. This may include but is not limited to procedures such as cosmetic surgery not tied to medical necessity, lifestyle or weight loss programs, and alternative treatments like homeopathy or acupuncture unless proven effective and necessary. Moreover, over-the-counter medications and most dietary supplements are typically not covered. Coverage exclusions can also extend to work-related injuries covered under workers' compensation, services provided by immediate family members, and care received outside of the plan's network without prior authorization. Please note that specific coverage can vary by plan and individual circumstances.
