Aortic Aneurysm Bill Assistance

My husband, Dave had an Aortic Aneurysm just 10 days after his 39th birthday. The doctors all said it was a miracle he survived. They said if I had waited a couple of minutes before rushing him to the hospital, he wouldn't have made it.  After being rushed to Boston and an 8 hour open heart bypass surgery (aortic dissection). They were able to replace a section of his aorta with an artificial part. They were not able to repair a tear in the lower section of his aorta. The surgeon said he wouldn't have survived that much work at once. Now the insurance company won't pay for 6 or if 12 days that he had to stay in the hospital. Although, he still needs help with daily activities, as simple as getting dressed and showering, three weeks later. We are both out of work and under a quarantine, because any sickness(or even high stress) at this point could be the end for him. After surviving the scariest situation of our lives . His family needs him to stay strong.  We do not know how we are going to manage paying our regular bills now, nevermind the thousands of dollars for the medical bills. Things are so scary right now, our 15 year old daughter is even trying to find work to help us get through this. We ask anyone who can spare anything to help us get through to be kind and share. Any help will be greatly appreciated.
