ICD-10 Code K92.0 – Hematemesis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K92.0 – Hematemesis
What it is
Hematemesis means vomiting blood or material that looks like blood from the upper gastrointestinal tract. Use this code when the record documents blood in emesis, regardless of the underlying cause.
Clinical signs
Common findings include vomiting bright red blood or coffee-ground material. Clinical features vary; refer to documentation and note whether the bleeding source is suspected to be upper gastrointestinal.
When to use this code
Use K92.0 when the provider documents hematemesis as a diagnosis or presenting problem. It is appropriate when the note describes blood in vomit without a more specific confirmed cause. If the chart identifies a definite underlying condition, code that condition as directed by documentation.
Do not use for
Do not use this code for melena, rectal bleeding, or coughing up blood. If the source is unclear or another diagnosis is documented, check documentation before assigning K92.0.
Coding tip
Code the documented symptom exactly, and look for any confirmed cause that may require additional coding.
