Ulcer of intestine

This code represents a non-specific ulceration occurring anywhere within the small or large intestine, excluding the duodenum. It signifies a localized break in the mucosal lining of the intestinal wall, often causing pain, bleeding, or other gastrointestinal symptoms.

Use this code when documentation specifies an "intestinal ulcer" without further anatomical precision within the small or large bowel, and without mention of perforation. This diagnosis is typically supported by endoscopic findings, imaging, or surgical reports confirming an ulcer in the intestine.

• Carefully review documentation to rule out more specific ulcer locations (e.g., duodenal, jejunal) or types (e.g., peptic, gastrojejunal) which have their own distinct codes.
• Always check for documentation of perforation; if present, a different code (K63.1) must be used.
• Ensure the ulcer is not related to inflammatory bowel disease (e.g., ulcerative colitis, Crohn's disease), as those conditions have specific codes that would take precedence.
