Final answer:
Medicare Supplement policies must cover pre-existing conditions after 6 months, ensuring continuity of care for enrollees. This complements the Medicare system established in 1965 specifically for citizens over the age of 65.
Step-by-step explanation:
Under Medicare Supplemental policies, coverage for pre-existing conditions must be provided after the policy has been in effect for a minimum of 6 months unless the condition is specifically excluded in the policy. This rule ensures that beneficiaries who are switching from one health plan to another or who are enrolling in a plan for the first time do not face a lack of coverage for conditions that existed before the new policy began.
Created in 1965, Medicare is a federal system of health insurance primarily for people over sixty-five years old, aiming to help these citizens meet their primary medical care needs. It represents a significant step forward in ensuring that older Americans have access to healthcare.
