Crohn's disease, unspecified, with fistula

This code signifies a diagnosis of Crohn's disease, an inflammatory bowel disease (IBD) that can affect any part of the gastrointestinal tract, where the specific location or type of Crohn's is not documented. The "with fistula" component indicates the presence of an abnormal connection between two epithelialized organs or vessels, or between an organ and the skin, as a complication of the Crohn's disease.

Use this code when the medical record clearly states a diagnosis of Crohn's disease and explicitly mentions the presence of a fistula, but does not specify the anatomical location of the Crohn's disease (e.g., Crohn's of small intestine, large intestine). Documentation must confirm both the Crohn's diagnosis and the fistula. This code is appropriate when the physician has not provided further specificity regarding the Crohn's disease itself.

• Ensure documentation explicitly links the fistula to the Crohn's disease.
• If the anatomical location of the Crohn's disease is specified (e.g., small intestine, large intestine), a more specific code from the K50.1-K50.8 series should be used, along with the appropriate fifth and sixth characters for "with fistula."
• Do not use this code if the fistula is unrelated to the Crohn's disease or if the Crohn's disease is documented without a fistula.
