What is primary coverage for someone retired with Medicare due to age?

Medicare serves as the primary coverage for individuals who are retired and qualify for Medicare based on age, typically when they reach 65 years old. This program is designed specifically for seniors and individuals with certain disabilities. When a person is enrolled in Medicare, it becomes the first source of health insurance coverage, which means any medical expenses they incur will first be paid for by Medicare before any other secondary insurance plans, like Medicaid or private insurance, come into play.

Medicaid primarily assists individuals with limited income and resources and is not typically the primary coverage for retirees who are eligible for Medicare. TRICARE is a health care program for military members and their families, which would not apply to retirees who have not served in the military. Private insurance can serve as a supplemental plan or secondary coverage but cannot be first in line when Medicare is already in place. Therefore, Medicare is the correct answer as it directly addresses the primary coverage needs for retirees in this scenario.
