Summary & Overview
CPT 43753: Gastric Intubation with Lavage
CPT code 43753 denotes gastric intubation with lavage — placement of a gastric tube, instillation of fluid to wash the stomach, and aspiration of the lavage. Nationally, this procedure is a time-sensitive intervention used for acute presentations such as overdose, upper gastrointestinal hemorrhage, bowel obstruction with proximal decompression needs, and severe trauma. It matters for hospitals and emergency departments because it can alter immediate clinical management and influence resource utilization and billing for acute care encounters.
Key payers considered include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Clinical & Coding Specifications
Clinical Context
A typical scenario involves an adult patient arriving to the emergency department after an acute ingestion of a toxic medication and altered mental status. The emergency physician determines that gastric decontamination is indicated within the appropriate time window and obtains informed consent from the patient or surrogate. In the procedure room or ED resuscitation bay, the patient is positioned supine with head slightly elevated. A nasogastric or orogastric tube is measured and placed through the nose or mouth into the stomach using standard technique; placement is confirmed by auscultation and aspirate pH or radiograph as required by local policy. The provider instills aliquots of saline or water to lavage gastric contents and suctions them back, repeating until returned fluid is clear or the desired volume is achieved. Continuous monitoring of airway, oxygenation, and vital signs occurs; suctioning and fluids are handled by the nursing and respiratory teams. Typical indications include overdose, gastrointestinal bleeding with irrigation for diagnostic/therapeutic reasons, bowel obstruction with decompression, and severe trauma requiring gastric evacuation prior to surgery. Typical site of service is the Emergency Department or inpatient critical care unit; outpatient/ambulatory settings are uncommon. Documentation includes indication, tube size and route (nasogastric vs orogastric), confirmation method, volumes instilled and recovered, patient tolerance, complications (if any), and time of procedure.
