Other diseases of stomach and duodenum

This code represents various specified but uncommon conditions affecting the stomach and duodenum that are not classified elsewhere. These can include functional disorders, structural abnormalities, or other pathological processes of these organs. It is used when a more specific diagnosis within the K31 category is not available or appropriate.

Use this code for documented conditions of the stomach or duodenum that do not fit into more specific ICD-10-CM codes, such as gastroparesis, pylorospasm (adult), or specified functional dyspepsia not otherwise classified. Documentation should clearly state the specific condition or symptom complex that points to a "specified but not elsewhere classified" diagnosis of the stomach or duodenum.

• Avoid using this code as a default for unspecified stomach or duodenal issues; always seek a more precise diagnosis if possible.
• Review documentation carefully to ensure the condition is truly "other specified" and not an unspecified condition (e.g., K31.9) or a more specific K31 subcategory.
• Consider sequencing this code after a primary symptom code if the underlying cause is not fully elucidated but a specific "other" condition is documented.
