There are two government programs that offer health benefits to disabled persons.
Medicare is not based on financial need. It provides medical benefits for qualified disabled adults who were employed for a certain period of time prior to becoming disabled. Once a person has been entitled to SSDI benefits due to disability for 24 months, they are eligible for Medicare. There are 4 separate parts of Medicare. Part A is for hospital care. Part B is for doctors, medical tests and procedures. Part C is actually an alternative plan that is instead of Part A, B, and D. Part D is for prescription drug coverage.
Medicaid is based on financial need. It is not "Obamacare." Hospital care, outpatient care, and prescription drugs can be provided. There are other ways to qualify for Medicaid, but receipt of SSI is one method.
