Final answer:
Individuals with ESRD or ALS do not have to endure a waiting period for Medicare coverage to begin, unlike those who qualify due to other disabilities.
Step-by-step explanation:
When applying for Medicare, individuals with ESRD (End-Stage Renal Disease) or ALS (Amyotrophic Lateral Sclerosis) do not have to wait for a coverage waiting period that typically applies to those who qualify for Medicare due to disability. In the case of ALS, Medicare coverage begins the same month disability benefits are awarded. In contrast, for ESRD patients, Medicare coverage generally starts on the fourth month of dialysis treatments but can start earlier if the individual takes part in home dialysis training or receives a kidney transplant.
