K29.91
ICD-10-CMThis code signifies inflammation of both the stomach and duodenum, where the specific cause or type of inflammation is not documented, and there is evidence of associated bleeding. The bleeding can manifest as hematemesis, melena, or positive occult blood tests.
Use this code when the physician documents "gastroduodenitis with bleeding" without specifying the etiology (e.g., acute, chronic, erosive). Documentation should clearly indicate both inflammation of the gastroduodenal lining and an active or recent bleed attributable to this inflammation.
