2025 CPT code 43755
(Active) Effective Date: N/A Revision Date: N/A Surgery - Gastric Procedures Digestive System Feed
Gastric intubation and aspiration for diagnostic purposes; collection of multiple fractional specimens with gastric stimulation.
Modifiers may be applicable depending on the circumstances of the procedure (e.g., 50 for bilateral procedures, 52 for reduced services, etc.).Consult the CPT manual for details.
The medical necessity for this procedure is established by the presence of clinical symptoms or findings suggestive of disorders of gastric acid secretion or other gastric abnormalities.These include, but are not limited to, Zollinger-Ellison syndrome, gastric ulcers, and unexplained gastrointestinal symptoms.Appropriate diagnostic testing is necessary for proper management and treatment.
The physician is responsible for performing the gastric intubation and aspiration, administering the stimulant, collecting the specimens, and interpreting the results.This requires appropriate patient preparation, anesthesia administration (if needed), and monitoring for adverse reactions to the stimulant.
In simple words: The doctor inserts a tube into your stomach to collect samples of stomach fluid.They give you a medicine to make your stomach produce more acid, then take several samples to test in a lab. This helps them understand how your stomach is working.
This CPT code encompasses the procedure involving gastric intubation (insertion of a tube into the stomach) and aspiration (removal of stomach contents) for diagnostic reasons.Multiple fractional specimens of gastric secretions are collected after stimulating gastric acid production using a stimulant (e.g., histamine, insulin, pentagastrin, calcium, secretin). The procedure may utilize a single or double lumen tube.Drug administration is included, but the fluid used to administer the drug is not separately reported.The collected specimens are sent to the laboratory for analysis of gastric content volume, pH, or other secretory studies.This is also known as a gastric secretory study.
Example 1: A patient presents with symptoms suggestive of Zollinger-Ellison syndrome.The physician orders a gastric secretory study (43755) to measure basal and stimulated gastric acid secretion to determine the diagnosis., A patient with suspected gastric hypersecretory state undergoes a gastric secretory study (43755) with secretin stimulation to evaluate excessive acid production., Following a gastric bypass surgery, a patient experiences persistent vomiting and abdominal pain.A gastric secretory study (43755) with pentagastrin stimulation is performed to assess for acid hypersecretion or other secretory abnormalities.
* Detailed history and physical examination documenting the patient's symptoms and clinical indication for the procedure.* Preoperative assessment, including medication reconciliation.* Informed consent documentation.* Intraoperative notes describing the technique of gastric intubation, aspiration, and stimulant administration.* Specific types and amounts of stimulants used.* Details on the collection and handling of multiple fractional specimens.* Postoperative assessment, including any complications.* Pathology report with the results of the laboratory analysis.
** This procedure may be performed in conjunction with other diagnostic tests, such as endoscopy.Always confirm with the payer's specific coding guidelines and medical necessity criteria.
