Chronic atrophic gastritis
ICD-10 K29.4 is a used to indicate a diagnosis of chronic atrophic gastritis.
Chronic atrophic gastritis is a long-term inflammation of the stomach lining characterized by the loss of gastric glandular cells and replacement with intestinal-type epithelium. Clinically, patients may present with symptoms such as abdominal pain, nausea, vomiting, and dyspepsia. The condition can lead to complications such as gastric ulcers and an increased risk of gastric cancer. The anatomy involved includes the gastric mucosa, which undergoes atrophy, leading to decreased acid production and impaired digestion. Disease progression can vary; some patients may remain asymptomatic for years, while others may experience significant gastrointestinal symptoms. Diagnostic considerations include endoscopic evaluation and biopsy to confirm atrophy and rule out other conditions. Serological tests for antibodies against Helicobacter pylori, as well as vitamin B12 levels, may also be utilized to assess for associated deficiencies and confirm the diagnosis.

K29.4 specifically covers chronic atrophic gastritis, which may arise from chronic H. pylori infection, autoimmune conditions, or prolonged use of certain medications. It is characterized by atrophy of the gastric mucosa and may lead to intestinal metaplasia.
K29.4 should be used when there is clear evidence of chronic atrophic changes in the gastric mucosa, typically confirmed through biopsy. It should be differentiated from acute gastritis (K29.0) and other forms of chronic gastritis that do not involve atrophy.
Documentation should include a comprehensive clinical history, results from endoscopic examinations, biopsy findings indicating atrophy, and any relevant laboratory tests that support the diagnosis of chronic atrophic gastritis.
