I find the family history to be the most useless part of my history.
For some doctors, I'm sure it's really useful. If you are evaluating a patient with chest pain, it's useful to know that their father had a heart attack at age 42. But considering every patient I've seen has already had a diagnosis, it ends up being completely useless to me.
Unfortunately, I don't get to decide what is useful or not. If I write a 30-page history and physical, I can only bill at the very lowest level unless I include a family history. So you can bet I'm asking about it.
