CPT® Code 82926
Deleted

Official Description

Gastric acid, free and total, each specimen

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 82926 refers to the analysis of gastric acid, specifically measuring both free and total acid levels from each specimen collected. This procedure involves obtaining a sample of gastric acid from the stomach, which is then subjected to laboratory analysis to determine its chemical composition. The analysis is crucial for understanding the acid production in the stomach, which can be indicative of various gastrointestinal conditions. The distinction between free and total acid is important; free acid refers to the hydrochloric acid that is not bound to other substances, while total acid includes both free acid and any acid that is bound to other compounds. This test is essential for diagnosing conditions related to abnormal gastric acid secretion, such as peptic ulcers or gastroesophageal reflux disease (GERD). If only free or total acid is tested, the appropriate code to use would be CPT® Code 82928.

1. Indications

The procedure associated with CPT® Code 82926 is indicated for the evaluation of gastric acid secretion levels. It is typically performed in the following scenarios:

  • Peptic Ulcers The test may be indicated for patients suspected of having peptic ulcers, as abnormal acid levels can contribute to ulcer formation.
  • Gastroesophageal Reflux Disease (GERD) This analysis can help assess acid production in patients experiencing symptoms of GERD, aiding in the diagnosis and management of the condition.
  • Gastritis Patients with gastritis may undergo this test to evaluate the acid levels in the stomach, which can influence treatment decisions.
  • Other Gastrointestinal Disorders The procedure may also be indicated for various other gastrointestinal disorders where acid secretion levels are of clinical interest.

2. Procedure

The procedure for CPT® Code 82926 involves several key steps to ensure accurate collection and analysis of gastric acid samples.

  • Step 1: Preparation The patient is typically required to fast for a specified period before the procedure to ensure that the gastric contents are not influenced by recent food intake. This fasting period is crucial for obtaining a clear and accurate measurement of gastric acid levels.
  • Step 2: Sample Collection A sample of gastric acid is collected, usually through a nasogastric tube or during an endoscopic procedure. The method of collection is important to ensure that the sample accurately reflects the gastric acid present in the stomach.
  • Step 3: Laboratory Analysis Once the sample is collected, it is sent to a laboratory where it undergoes analysis to measure both free and total acid levels. The laboratory uses specific chemical assays to determine the concentration of hydrochloric acid and other components in the gastric fluid.
  • Step 4: Interpretation of Results After analysis, the results are interpreted by a healthcare professional. The findings can provide insights into the patient's gastric acid production and help guide further diagnostic or therapeutic decisions.

3. Post-Procedure

After the procedure associated with CPT® Code 82926, patients may be monitored for any immediate side effects related to the sample collection method, especially if an endoscopic approach was used. Recovery is generally quick, and patients can usually resume normal activities shortly after the procedure. The results of the gastric acid analysis will be discussed with the patient during a follow-up appointment, where the healthcare provider will explain the findings and any necessary next steps in management or treatment based on the acid levels measured.
