Properly Coding a Follow-up Exam
Published on Fri May 01, 1998
Question: A patient presents with painful urination and a lab test confirms a UTI. Medication is prescribed and the patient is told to come back in a couple of weeks for a follow-up visit. The initial visit was linked to the diagnosis code for Urethritis (597.80). I would like to know if you still use the same diagnosis code when the patient returns for the follow up visit but now presents symptom and disease free?

Answer: Yes. You know youre providing a successful service when a patient is treated and then returns apparently cured of the disease. This is what you hope for, but as long as the return visit is specifically to follow-up on the original diagnosis you use the same diagnosis code. Even though you know at the end of the visit that the patient no longer has the disease, the follow-up visit is to make sure.
Tip: Often a diagnosis code for the same problem in two separate visits will change. For example, a patient comes in with symptoms and that visit is linked to a diagnosis code for the symptoms. But between the first and second visit diagnostic tests confirm a diagnosis, so in the follow up visit the diagnosis code changes. Remember, the diagnosis code should always reflect what is definitely known.
