ICD-10 Code K56.41 – Fecal impaction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K56.41 – Fecal impaction
What it is
Fecal impaction means a large, hardened stool mass is stuck in the rectum or colon and cannot be passed normally. It is a specific diagnosis used when documentation confirms impacted stool.
Clinical signs
Common findings include constipation, rectal fullness, abdominal discomfort, and inability to pass stool despite the urge. Clinical features vary; refer to documentation.
When to use this code
Use K56.41 when the provider documents fecal impaction, impacted stool, or disimpaction related to retained stool. It may be appropriate in emergency, inpatient, or outpatient notes when the condition is clearly identified. Check documentation if the record only mentions constipation without impaction.
Do not use for
Do not use this code for simple constipation, bowel obstruction, or ileus unless fecal impaction is specifically documented. If the note is unclear, check documentation.
Coding tip
Code fecal impaction only when the provider states it explicitly or documents disimpaction.
