Acute infarction of intestine, part and extent unspecified

This code signifies a sudden and severe obstruction of blood flow to a segment of the intestine, leading to tissue death (infarction). The specific portion of the intestine affected (e.g., small or large bowel) and the extent of the damage are not documented.

Apply this code when medical records clearly indicate an acute intestinal infarction, but the physician's documentation does not specify the exact anatomical location or the full extent of the affected bowel. This is often used in initial presentations or when diagnostic workup is incomplete.

• Only use this code when the specific part and extent are truly unspecified in the documentation.
• Prioritize more specific codes (e.g., K55.011, K55.021) if the documentation allows.
• Query the provider for clarification on the specific intestinal segment and extent of infarction if possible.
