What ICD-10 Codes are Used for Chronic Diarrhea? 

Below are commonly used chronic diarrhea ICD-10 codes, clinical descriptions, and essential information.

K52.2

This code is the go-to choice when chronic diarrhea emerges from noninfective origins, such as inflammatory bowel disease or colitis. Its application encompasses a range of noninfective gastrointestinal disturbances.

K59.1

When chronic diarrhea lacks a discernible organic cause, this code steps in. It finds relevance in cases closely linked to irritable bowel syndrome, where the diarrhea's underlying mechanism remains elusive.

K58.0

Deployed for scenarios where chronic diarrhea emerges as the hallmark of irritable bowel syndrome, this code precisely depicts the syndrome's predominant symptom.

K52.89

This code's utility shines when chronic diarrhea arises from distinct noninfective conditions that defy classification under other codes. It serves as a catch-all for specific yet unconventional cases.

K59.00

Despite its emphasis on constipation, this code possesses the flexibility to cover instances of irritable bowel syndrome where episodes of diarrhea alternate with constipation. It encapsulates the syndrome's multifaceted nature.

K52.9

This code's purpose becomes evident when the intricate underpinnings of chronic diarrhea evade clear identification. It suits cases where the precise causal factor remains uncharted territory.

K59.4

When chronic diarrhea falls outside the scope of other specific codes, this code offers a catch-all category for cases that require classification but lack more targeted codes.
