Hi Chris,
I will try to help!
For Box 6 I would say enter the admit date thru the discharge date. Even though the discharge date isn't covered, if you don't put it then they will think the day before the discharge is the discharge date.
For Box 35 I would do the same thing.
Box 39 is for value codes, and I don't see one that applies to what you have described. It is not a required field, but if you see one that applies you should use it.
Box 45 - you got it.
Now that didn't seem so bad when you take it one box at a time.
Good luck!
Michele
