K29.90
ICD-10-CMThis code describes a generalized inflammation of both the stomach and the duodenum when the specific type or cause of the inflammation is not documented. It indicates a non-specific inflammatory process affecting the upper gastrointestinal tract without any associated hemorrhage.
Use this code when the medical record documents "gastroduodenitis" without further specification of its type (e.g., acute, chronic, erosive) and explicitly states or implies the absence of bleeding. This is appropriate when diagnostic workup is incomplete or when the physician's final diagnosis lacks specificity regarding the nature of the inflammation.
