ICD-10 Code K29.6 – Other gastritis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K29.6 – Other gastritis
What it is
K29.6 identifies gastritis that is not classified elsewhere. Use it when documentation says “other gastritis” or names a gastritis type that does not fit a more specific ICD-10 category.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include epigastric discomfort, nausea, vomiting, or endoscopic evidence of gastric mucosal inflammation.
When to use this code
Use K29.6 when the clinician documents gastritis as “other” or describes a non-specific subtype that is not separately indexed. It also fits when the record confirms gastritis, but no more precise category is supported. Check documentation if the cause is clearly stated.
Do not use for
Do not use this code for gastritis with a more specific ICD-10 description, such as acute, chronic, or alcohol-related forms. If the note identifies a different etiology or a peptic ulcer, code that condition instead.
Coding tip
Code K29.6 only when the documentation supports “other” gastritis and no more specific gastritis code applies.
