Complete intestinal obstruction, unspecified as to cause

This code signifies a total blockage of the intestinal tract where the underlying reason for the obstruction is not yet identified or documented. It indicates a severe disruption of normal bowel function, preventing the passage of contents.

Use this code when documentation clearly states a "complete intestinal obstruction" but lacks specific details regarding its etiology (e.g., adhesions, hernia, tumor). This is often an initial diagnosis in an emergency setting before definitive diagnostic workup is complete.

• Avoid using this code if the cause of the obstruction is known; instead, code to the specific cause (e.g., K56.5 for intestinal adhesions with obstruction).
• Always query the provider for clarification on the cause if possible, as a more specific code will improve data accuracy and reimbursement.
• This code is typically a principal diagnosis in acute care settings when the patient presents with symptoms of complete bowel obstruction.
