Gastritis and duodenitis
Chapter 11:Diseases of the digestive system
ICD-10 K29 is a used to indicate a diagnosis of gastritis and duodenitis.
Gastritis and duodenitis refer to the inflammation of the stomach lining and the duodenum, respectively. These conditions can present with symptoms such as abdominal pain, nausea, vomiting, and dyspepsia. The anatomy involved includes the gastric mucosa and the duodenal lining, which can be affected by various factors including infections (e.g., Helicobacter pylori), excessive alcohol consumption, prolonged use of nonsteroidal anti-inflammatory drugs (NSAIDs), and autoimmune disorders. Disease progression may lead to chronic gastritis or duodenitis, which can result in complications such as peptic ulcers or gastric atrophy if left untreated. Diagnostic considerations include endoscopy, biopsy, and imaging studies to assess the extent of inflammation and rule out malignancies. Laboratory tests may also be performed to identify underlying causes, such as H. pylori infection or anemia. Accurate diagnosis is essential for effective management and treatment, which may involve dietary modifications, medications to reduce stomach acid, and addressing any underlying causes.

K29 encompasses acute gastritis, chronic gastritis, and duodenitis. It includes conditions caused by infections, irritants, and autoimmune responses. Specific diagnostic criteria involve clinical symptoms, endoscopic findings, and histological evidence.
K29 should be used when the primary diagnosis is gastritis or duodenitis, particularly when the inflammation is confirmed through clinical evaluation. It should be differentiated from codes like K21, which pertains to reflux disease, based on the presenting symptoms and diagnostic findings.
Documentation should include a detailed history of symptoms, results from diagnostic tests (e.g., endoscopy, biopsy), and any relevant laboratory findings. Clear notes on treatment plans and patient responses are also essential for supporting the use of K29.
