What are the eligibility requirements for Original Medicare?

The eligibility requirements for Original Medicare are focused on age and specific health conditions. Individuals become eligible for Original Medicare when they reach the age of 65. Additionally, individuals under the age of 65 can qualify if they have been receiving Social Security Disability Insurance (SSDI) for 24 months, or if they have diagnosed conditions such as End-Stage Renal Disease (ESRD) or Amyotrophic Lateral Sclerosis (ALS).

This comprehensive eligibility framework ensures that those who are elderly, as well as those with significant health challenges, have access to necessary healthcare services through Medicare. The other choices provided do not align with these established eligibility criteria, as they either restrict eligibility unnecessarily or focus on factors that are not part of the Medicare qualification process.
