Surgical after care
If the patient is presenting to the office for a routine post-op visit then the 99024 code can be used for tracking purposes (we do not even send a claim to insurance).
If the patient has issues unrealted to the surgery, and an E/M is performed, that service can be coded as an established patient visit (level based on documentation) with a -24 modifier. BUT ... this has to be a problem unrelated to surgery ... NOT a chronic condition that just happens to exist.
So, for example, your abscess patient comes to the office 3 days after I&D for a wound check. This patient happens to have DM. You do NOT code an established office visit just because the patient happens to have a chronic condition.
On the other hand, your abscess patient comes to the office 3 days after I&D for a wound check, and also mentions that he has a cough, sore throat and feels feverish. The workup of these URI symptoms (or possible flu) is completely unrelated to the abscess and I&D and would be coded separately with a -24 modifier.
Hope that helps.
