Final answer:
Medicare is the federal insurance program that enrolls people of any age with kidney failure who are being treated with dialysis.
Step-by-step explanation:
The federal insurance program enrolls people of any age if they have kidney failure and are on dialysis through Medicare. This program is not just for those over the age of 65 but also for individuals who meet other eligibility criteria, such as having certain disabilities or chronic conditions like end-stage renal disease (ESRD), which requires dialysis treatment. While Medicaid provides health insurance to low-income individuals and families, including low-income mothers with children, the elderlies, and the disabled, it is Medicare that specifically provides coverage for dialysis patients regardless of age. Medicare is a federal health insurance program primarily for individuals aged 65 and older, but it also covers certain individuals with disabilities, including those with end-stage renal disease (kidney failure).
