If you are enrolled in a Medicare Advantage Plan, your plan’s cost-sharing may apply when seeing in-network providers.

During the course of your mammogram screening, your provider may discover and need to investigate or treat a new or existing problem. This additional care is considered diagnostic, meaning your provider is treating you because of certain symptoms or risk factors. Medicare may bill you for any diagnostic care you receive during a preventive visit.

Medicare has specific billing modifiers that your provider should use when submitting claims for services when the gender marker on your Social Security record could cause an incorrect coverage denial.
