Anorectal fistula, simple, recurrent

This code signifies a previously treated anorectal fistula that has reappeared and is characterized by a single, uncomplicated tract without branching or significant tissue destruction. It represents a re-establishment of the abnormal connection between the anal canal or rectum and the perianal skin.

Apply this code when documentation indicates a patient presents with a recurrent, simple anorectal fistula that has been previously managed. The physician's notes should clearly state "recurrent" and describe the fistula as "simple" or "uncomplicated," often with a single external opening.

• Differentiate from complex recurrent fistulas (K60.523) which involve multiple tracts or significant tissue involvement.
• Ensure the documentation explicitly states "recurrent" to justify this code over an initial simple fistula (K60.511).
• Consider sequencing with codes for any associated conditions, such as Crohn's disease, if applicable.
