The Immediate Access for the Terminally Ill Act aims to improve access to disability insurance benefits for individuals diagnosed with incurable terminal illnesses. The main goal is to allow these individuals to receive benefits without having to wait, which can be crucial during their limited time left. One of the key provisions of this legislation is that it allows individuals with specific terminal illnesses, as listed in the Compassionate Allowance list, to receive disability insurance benefits starting from the first month they qualify, rather than facing a waiting period.
