ICD-10 Code K92 – Other diseases of digestive system (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K92 – Other diseases of digestive system
What it is
K92 is a broad diagnosis code for digestive system conditions that do not fit a more specific ICD-10 category. Use it when the record documents a digestive disorder, but the exact disease is not identified.
Clinical signs
Clinical features vary; refer to documentation. Records may note nonspecific gastrointestinal complaints, abnormal digestive findings, or a digestive disorder without a precise named diagnosis.
When to use this code
Use K92 when the provider documents an “other” digestive disease and no more specific code is available. It may also apply when the chart confirms a digestive system condition, but the final diagnosis remains unspecified. Check documentation before assigning it.
Do not use for
Do not use K92 when the record supports a specific digestive diagnosis with its own code. Avoid it for symptoms alone, such as abdominal pain or nausea, unless the provider clearly documents a coded digestive disease.
Coding tip
Look for the most specific digestive diagnosis in the note before defaulting to K92.
