Anal fistula, simple, recurrent

This code signifies a simple anal fistula that has recurred after previous treatment. An anal fistula is an abnormal tunnel connecting the anal canal to the skin near the anus, often resulting from an anal abscess. A "simple" fistula typically involves a single, straight tract without significant branching or involvement of complex sphincter musculature.

Apply this code when documentation clearly indicates a previously treated anal fistula has reappeared, and the physician describes it as simple. This code is appropriate for patients presenting with symptoms such as persistent drainage, pain, or swelling around the anus, where a physical exam or imaging confirms a recurrent, uncomplicated fistula.

• Ensure documentation specifies "recurrent" and "simple" to support this specific code.
• Distinguish from initial presentations of simple anal fistulas (K60.311) or complex recurrent fistulas (K60.314).
• Code any associated conditions, such as Crohn's disease, if documented as causative or co-existing.
