When you apply for SSI, you need to give SSA some basic information about yourself, like your Social Security number, place of birth, and names of current and former spouses.
You should also tell SSA about your medical conditions and treatment history. This includes the names and addresses of your doctors, dates and places of hospital stays, a list of medications you take, and dates of medical tests. You will need to sign a form to let SSA get your medical records. You can also give them copies of your records when you apply.
If you apply for SSI, you will also need to give SSA information about your finances, like your income and any assets you own (home, vehicles, bank accounts).
