ICD-10 Code K92.9 – Disease of digestive system, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K92.9 – Disease of digestive system, unspecified
What it is
K92.9 is a nonspecific code for a digestive system disorder when the exact gastrointestinal condition is not identified in the record. Use it when documentation confirms a digestive disease but does not name a more specific diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Digestive disorders may present with abdominal pain, nausea, vomiting, diarrhea, constipation, bleeding, or other gastrointestinal complaints, but the code itself does not define a specific symptom pattern.
When to use this code
Use K92.9 when the provider documents a disease of the digestive system and no further detail is available. It may fit incomplete assessments, brief encounter notes, or situations where the final diagnosis remains unspecified. If the chart names a more precise condition, code that instead.
Do not use for
Do not use K92.9 when the record identifies a specific digestive diagnosis, such as gastritis, ulcer disease, or intestinal obstruction. Do not use it for symptoms alone unless the provider documents an actual digestive disease.
Coding tip
Review the assessment carefully and query for specificity whenever the digestive condition is unclear.
