Acute ischemia of intestine, part and extent unspecified

This code signifies a sudden, temporary reduction in blood flow to the intestines, which is expected to resolve without permanent damage. It indicates that the specific segment of the intestine affected (e.g., small bowel, large bowel) and the precise extent of the ischemia are not documented or are unknown. This condition can lead to abdominal pain, nausea, and vomiting.

Apply this code when documentation clearly states "acute reversible ischemia of intestine" without further specification of the affected part or extent. It is appropriate for cases where the physician has not yet identified the specific intestinal segment involved or when the ischemia is presumed to be transient and not leading to infarction. Supporting documentation would include clinical notes describing acute intestinal ischemia that is not yet categorized as chronic or irreversible.

• Do not use this code if the documentation specifies a particular segment of the intestine (e.g., small intestine, large intestine) or if the ischemia is described as chronic or irreversible.
• Distinguish carefully from codes indicating intestinal infarction (e.g., K55.01x, K55.02x), which represent irreversible tissue death.
• Always review the entire medical record for more specific details regarding the location and nature of the ischemia before assigning this unspecified code.
