Before the Affordable Care Act, if you had a history of back problems and needed health insurance, it was unlikely that your new insurance plan would cover any treatment related to your back problems until the policy had been in effect for a period of time.

Medical insurance, before the Obamacare sanction, tended to distinguish these previous ailments, leaving them out of the medical coverage insurance, as they originated during times when the insurance was not in force. In this way, the patient was left unprotected in the event of an aggravation of said health situation.
