CPT® Code 82930

The CPT® Code 82930 refers to the procedure of gastric acid analysis, which includes the measurement of pH if performed, for each specimen collected. This procedure involves obtaining a sample of the stomach contents, which is crucial for assessing the gastric acid levels present. Gastric acid primarily consists of hydrochloric acid, secreted by the parietal cells in the stomach lining. The analysis is essential for diagnosing conditions related to abnormal gastric acid secretion, such as hypersecretion, which can lead to complications like gastric ulcers or esophageal damage due to gastroesophageal reflux disease (GERD). Conversely, hyposecretion may indicate underlying health issues, including pernicious anemia, atrophic gastritis, or Ménétrier's disease. The gastric acid analysis is typically conducted in two phases: first, without stimulation to evaluate the basal acid output through multiple timed samples, and second, following the administration of a stimulant medication that enhances gastric secretion, allowing for further sample collection. Each specimen is meticulously analyzed using titration assays to determine various parameters, including volume, color, hydrogen ion concentration, and pH levels. It is important to note that the analysis of each specimen is reported separately, ensuring precise documentation and evaluation of the gastric acid levels.
