Which group of individuals can potentially enroll in Medicare due to their income status?

Individuals with specific disabilities or conditions can potentially enroll in Medicare because there are provisions in the Medicare program that allow for early access to benefits under certain circumstances. For example, individuals who are under 65 and have been receiving Social Security Disability Insurance (SSDI) for 24 months automatically qualify for Medicare. Additionally, those diagnosed with conditions such as End-Stage Renal Disease (ESRD) or Amyotrophic Lateral Sclerosis (ALS, also known as Lou Gehrig's disease) are also eligible for Medicare without having to wait for the 24-month SSDI period.

The other options refer to different aspects of Medicare eligibility. While low-income individuals can qualify for programs like Medicaid which work alongside Medicare, it is not exclusive to them. All seniors over 65 are eligible for Medicare, regardless of income status, disqualifying that option for this question. Lastly, while individuals with military service receive unique benefits through programs like TRICARE, this does not exclusively pertain to Medicare enrollment. Therefore, those with specific disabilities or conditions stand out as a distinct group that can enroll based on medical factors rather than solely age or income.
