What benefits can my friend get after heart surgery?

He had a heart attack at least 2 and a half months ago. Had triple heart bypass surgery. Now no job and no home and living in a hostel.He’s applied for benefits but they want I.D. He can’t locate his passport and doesn’t have a driving license.He has had no money for a long time.Isn’t there any interim mayment he can have? Whathelp can he get?

How long does heart surgery take to complete?

I’m writing a screenplay and I want to make it as believeable as possible, so if you know the answer, please share.

Here’s the situation:
The character was vacationing in California, had a heart attack and had to get heart bypass surgery. How long would it take for the character to have the surgery and recover. And how long would he have to be in the hospital for.
Thanks guys!
