Regional enteritis of unspecified site

This code represents an inflammatory bowel disease characterized by chronic inflammation of the gastrointestinal tract, specifically when the exact location of the inflammation is not documented. It indicates a diagnosis of Crohn's disease without specifying the affected segment of the small or large intestine.

This code is appropriate when the physician's documentation confirms a diagnosis of regional enteritis (Crohn's disease) but does not specify the anatomical site of involvement (e.g., ileum, colon, jejunum). It is used when the documentation is insufficient to assign a more specific code for Crohn's disease.

• Avoid using this code if a more specific site of involvement (e.g., small intestine, large intestine) is documented.
• Query the provider for clarification of the anatomical site if possible to allow for more specific coding.
• Do not confuse with ulcerative colitis, which is a distinct inflammatory bowel disease.
