Functional diarrhea
ICD-10 K59.1 is a billable code used to indicate a diagnosis of functional diarrhea.
Functional diarrhea, classified under ICD-10 code K59.1, is characterized by the presence of frequent, loose, and watery stools without any identifiable organic cause. This condition typically arises from disturbances in the normal functioning of the gastrointestinal tract rather than from structural abnormalities or infections. The anatomy involved primarily includes the intestines, particularly the colon, where water absorption is impaired, leading to increased stool liquidity. Patients may experience symptoms such as abdominal cramping, urgency, and a sense of incomplete evacuation. Disease progression can vary; while some individuals may experience intermittent episodes, others may have chronic symptoms that significantly impact their quality of life. Diagnostic considerations include ruling out other gastrointestinal disorders, such as irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), and infections. A thorough patient history, physical examination, and possibly stool studies are essential to confirm the diagnosis of functional diarrhea and to exclude other potential causes.

K59.1 specifically covers functional diarrhea, which is defined by the presence of loose stools without an identifiable organic cause. It is important to differentiate it from other types of diarrhea, such as infectious or inflammatory diarrhea.
K59.1 should be used when the diarrhea is functional in nature, meaning there are no identifiable structural or infectious causes. It is crucial to document the absence of other gastrointestinal disorders to justify the use of this code.
Documentation should include a detailed patient history, symptom description, and results from any tests conducted to rule out other gastrointestinal conditions. A clear statement indicating the functional nature of the diarrhea is essential.
