Achlorhydria
ICD-10 K31.83 is a billable code used to indicate a diagnosis of achlorhydria.
Achlorhydria is a condition characterized by the absence of hydrochloric acid in gastric secretions, which can lead to various gastrointestinal disturbances. Clinically, patients may present with symptoms such as bloating, indigestion, and malabsorption of nutrients, particularly vitamin B12 and iron, due to impaired digestion. The anatomy involved primarily includes the stomach, where parietal cells are responsible for producing gastric acid. Disease progression can lead to complications such as bacterial overgrowth, increased risk of gastrointestinal infections, and potential development of gastric cancer due to changes in gastric mucosa. Diagnostic considerations for achlorhydria typically involve gastric pH testing, endoscopy, and evaluation of gastric secretions. It is essential to differentiate achlorhydria from other conditions that may present with similar symptoms, such as hypochlorhydria or gastric outlet obstruction, to ensure appropriate management and treatment strategies.

K31.83 specifically covers achlorhydria, which may be associated with conditions such as autoimmune gastritis, pernicious anemia, and chronic atrophic gastritis. It is important to document the underlying cause when applicable.
K31.83 should be used when there is a confirmed diagnosis of achlorhydria, particularly when gastric pH testing indicates a lack of hydrochloric acid. It is crucial to differentiate it from hypochlorhydria (K31.84) where some gastric acid is present.
Documentation should include clinical symptoms, results from gastric pH testing, endoscopic findings, and any relevant laboratory tests that confirm the absence of gastric acid. A thorough clinical history is also essential.
