Second, for house calls to established patients, the lowest code is essentially equivalent to a 99212. Bottom line I like house calls. If I hated them, I wouldn't do them even if they were profitable. I suspect you wouldn't either. When we don't have a good, thorough experience with a particular aspect of medicine as residents, we tend not to gravitate toward those things in our practices.
Comfort comes from experience.
Without comfort in making house calls, we don't do them even though we can and should. My advice is to do just six house calls. You'll work out the logistics after the first two or three and, by the end of the sixth, have a sense of their value to you as a physician and as a person. If you don't like them, no sweat. Do them when you have to, but otherwise leave them to your colleagues.
