Hi, I'm concerned with how I should be billing for telephone conversations that the physicians are having with patients. I know that there are the 99339 and 99340 E/M codes that may be possible to use or is it acceptable to somehow add it in with a regular office visit to make the E/M code at a higher level? If so, how long from the actual face-to-face visit does the telephone call have to be done in order for it to be acceptable for billing? Thank you.
