Incomplete defecation

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015

Code Description

ICD-10 R15.0 is a billable code used to indicate a diagnosis of incomplete defecation.

Key Diagnostic Point:

Incomplete defecation refers to the sensation of an inability to completely evacuate the bowels during a bowel movement. Patients may describe this as feeling as though they still need to pass stool after having a bowel movement. This symptom can be associated with various gastrointestinal disorders, including constipation, rectal prolapse, or anal fissures. It may also arise from functional bowel disorders such as irritable bowel syndrome (IBS) or pelvic floor dysfunction. The sensation can lead to significant discomfort and distress, impacting the patient's quality of life. Clinically, it is important to differentiate between true incomplete evacuation and other causes of altered bowel habits. A thorough history and physical examination, along with appropriate diagnostic tests, are essential to identify underlying causes and guide management. Laboratory findings may include stool studies to rule out infections or malabsorption syndromes, while imaging studies may be necessary to evaluate structural abnormalities.
