Rectal fistula, unspecified

This code signifies an abnormal, uncharacterized connection between the rectum and another organ or the skin surface. It indicates the presence of a fistula originating from the rectum without further specification regarding its type, etiology, or anatomical connections.

Use this code when documentation confirms a rectal fistula but lacks details to classify it more specifically (e.g., rectovaginal, rectovesical, or perianal). This is appropriate when the provider's notes simply state "rectal fistula" without additional descriptive information.

• Avoid using this code if the documentation provides sufficient detail to assign a more specific rectal fistula code (e.g., K60.3 for anal fistula, unspecified).
• Always query the provider for more specific information if only "rectal fistula" is documented, as a more precise code often exists.
• Consider sequencing this code after any underlying conditions that may have caused the fistula, such as Crohn's disease (K50.-) or diverticulitis (K57.-).
