R11.13

Vomiting of fecal matter

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/11/2025

Code Description

ICD-10 R11.13 is a billable code used to indicate a diagnosis of vomiting of fecal matter.

Key Diagnostic Point:

Vomiting of fecal matter is a rare but serious clinical symptom that indicates a severe underlying gastrointestinal obstruction or dysfunction. This condition occurs when the contents of the intestines, including fecal material, are regurgitated through the mouth. It is often associated with conditions such as bowel obstruction, severe constipation, or advanced gastrointestinal diseases. The presence of fecal matter in vomit suggests that the obstruction is distal to the point of fecal accumulation, leading to a backup of intestinal contents. Patients may present with additional symptoms such as abdominal pain, distension, and signs of dehydration. Laboratory findings may reveal electrolyte imbalances, elevated white blood cell counts, or imaging studies showing obstruction. Prompt recognition and management are crucial, as this condition can lead to severe complications, including perforation, sepsis, and death if not treated urgently.

Complexity Factors

  • Requires understanding of gastrointestinal pathophysiology
  • Differentiation from other types of vomiting
  • Need for comprehensive documentation of clinical findings
  • Potential for multiple underlying causes

Audit Risk Factors

  • Inadequate documentation of the clinical scenario
  • Failure to link symptoms to a definitive diagnosis
  • Misinterpretation of the severity of the condition
  • Inconsistent coding practices across providers
