Final answer:
To have a Medigap plan, you must be enrolled in both Part A and Part B of Medicare.
Step-by-step explanation:
To have a Medigap plan, you must be enrolled in both Part A and Part B of Medicare. Part A covers hospital charges, while Part B covers physician services, medical tests, and outpatient visits.
Medicare is a healthcare program primarily for individuals who are eligible for Social Security benefits. It is not an insurance system offered only to people over sixty-five years old.
Therefore, the statement is true that to have a Medigap plan, you must be enrolled in Part A and B of Medicare.
