Crohn's disease of large intestine w intestinal obstruction

This code signifies Crohn's disease specifically affecting the large intestine, complicated by the presence of an intestinal obstruction. This obstruction can be partial or complete, leading to symptoms such as abdominal pain, distension, nausea, vomiting, and inability to pass stool or flatus.

Apply this code when documentation clearly indicates a diagnosis of Crohn's disease localized to the colon or large bowel, and there is an associated intestinal obstruction. Supporting documentation would include imaging reports (e.g., CT scan, barium enema) confirming the obstruction and physician notes detailing the Crohn's diagnosis and its colonic involvement.

• Ensure the documentation specifies the large intestine as the affected site of Crohn's, not just "Crohn's disease with obstruction."
• Do not use this code if the obstruction is due to an unrelated condition; the obstruction must be a direct complication of the Crohn's disease.
• Consider additional codes for specific types of obstruction (e.g., K56.609 for unspecified intestinal obstruction) if further detail is provided and appropriate.
