Mandatory supplemental benefits

Medical services not covered by Medicare that enrollees must purchase as a condition of enrollment in a Medicare Advantage Plan. Usually those services are paid for by premiums and/or cost sharing. Mandatory supplemental benefits can be different for each Medicare Advantage Plan. Medicare Advantage Plans must ensure that any particular group of Medicare beneficiaries does not use mandatory supplemental benefits to discourage enrollment.
