What is the eligibility criteria for Medicare regarding individuals under age 65?

Individuals under the age of 65 can qualify for Medicare primarily if they have specific health conditions, notably amyotrophic lateral sclerosis (ALS) or end-stage renal disease (ESRD). This eligibility criterion is established to ensure that those who are facing severe and often disabling health issues receive the necessary healthcare support that Medicare provides.

For instance, individuals diagnosed with ALS automatically qualify for Medicare, and those with ESRD typically become eligible after beginning dialysis or receiving a kidney transplant. This provision is significant as it addresses the healthcare needs of younger populations who may not fit the usual age criteria of 65 and older but still require advanced medical care due to their conditions.

In contrast, eligibility is not granted based on income levels, military service alone, or even a broad categorization of chronic illnesses that do not meet these specific conditions. Therefore, the focus on ALS and ESRD distinctly defines the eligibility framework for Medicare in relation to individuals under age 65.
