Support Veteran Dad's Heart Surgery Costs

My dad has been living with congestive heart failure for over 15 years, and it has finally caught up to him. He is currently in the hospital, waiting on how to deal with the current info of having another blood clot that is stopping further surgery from being performed to help regulate his heart.

We need help to cover some of the bills that the VA will not cover. He is a veteran that served during Desert Storm and doesn't have other insurance.
