United Health Coverage (UHC) Medicare Basics Practice Test 2025 - Free Medicare Basics Practice Questions and Study Guide

The eligibility for Medicare primarily focuses on individuals aged 65 or older, which aligns with the standard retirement age in the United States. In addition to this age criterion, Medicare also extends eligibility to certain younger individuals who have specific disabilities or medical conditions, such as End-Stage Renal Disease (ESRD) or Amyotrophic Lateral Sclerosis (ALS). These provisions are designed to ensure that those who have chronic illness or disability can access essential medical coverage.

Individuals under 50 typically do not qualify for Medicare unless they have a qualifying disability, which is not a general condition for enrollment. Therefore, option B accurately captures both the primary demographic of seniors and the important inclusion of some younger individuals with disabilities. This clear delineation of eligibility criteria is crucial for ensuring that those who need care receive it when they reach the necessary age or when facing certain health challenges.
