ICD-10 Code K92.8 – Other specified diseases of the digestive system (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K92.8 – Other specified diseases of the digestive system
What it is
K92.8 is a residual ICD-10-CM code for digestive system disorders that are documented but do not fit a more specific digestive diagnosis. Use it when the provider names a distinct digestive condition and no better code is available.
Clinical signs
Clinical features vary; refer to documentation. The record should describe a digestive system disorder that is not otherwise classified, with enough detail to support the unspecified but specific nature of the condition.
When to use this code
Use K92.8 when the clinician documents an “other specified” digestive disorder and the chart does not support a more exact code. It is appropriate when the diagnosis is clear in the note but the ICD-10 index directs you to this residual category. Do not use it simply because the chart is incomplete.
Do not use for
Do not use K92.8 for signs, symptoms, or generalized abdominal complaints without a documented diagnosis. If a more specific digestive code is available, or the condition is truly unspecified, choose that code instead.
Coding tip
Check the provider’s exact wording and the Alphabetic Index before assigning K92.8.
