Other diseases of stomach and duodenum
Chapter 11:Diseases of the digestive system
ICD-10 K31 is a used to indicate a diagnosis of other diseases of stomach and duodenum.
K31 encompasses a variety of diseases affecting the stomach and duodenum that do not fall under more specific categories. Conditions such as gastritis, peptic ulcers, and gastric polyps may be included, presenting with symptoms like abdominal pain, nausea, vomiting, and changes in appetite. The stomach and duodenum are critical components of the digestive system, responsible for the initial stages of food digestion and nutrient absorption. Disease progression can vary; for instance, chronic gastritis may lead to atrophy of the gastric mucosa, increasing the risk of gastric cancer. Diagnostic considerations include endoscopy, imaging studies, and laboratory tests to assess for H. pylori infection, anemia, or other underlying conditions. Accurate diagnosis is essential for effective management, which may involve lifestyle modifications, pharmacotherapy, or surgical interventions depending on the severity and nature of the disease.

K31 covers a range of conditions including chronic gastritis, gastric polyps, and functional dyspepsia. Each condition has specific diagnostic criteria, often requiring endoscopic evaluation or imaging studies to confirm.
K31 should be used when the specific diagnosis is not clearly defined or when multiple diseases of the stomach and duodenum are present that do not fit into more specific categories like K25 or K29.
Documentation should include clinical findings, diagnostic test results, treatment plans, and follow-up notes. Clear evidence of symptoms and the rationale for diagnosis is crucial for supporting the use of K31.
