Official Description

Gastric intubation and aspiration(s) therapeutic, necessitating physician's skill (eg, for gastrointestinal hemorrhage), including lavage if performed

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 43753 involves gastric intubation and therapeutic aspiration, which requires the skill of a physician, particularly in cases such as gastrointestinal hemorrhage. Gastric intubation is a medical procedure where a tube is inserted into the stomach through the nose or mouth to facilitate the removal of gastric contents or to administer medications and fluids. The process begins with the selection of the most open nostril for tube insertion, followed by the application of local anesthesia using viscous lidocaine to minimize discomfort. The physician estimates the necessary length of the tube for proper placement in the stomach and marks it accordingly. The tube is then carefully advanced through the nasal passage, oropharynx, and esophagus until it reaches the stomach. Verification of correct placement is crucial and is typically done by either instilling air into the stomach and listening for the sound of air or by aspirating gastric contents. In addition to the intubation, the procedure may include therapeutic aspiration, where the physician removes gastric contents to address specific medical conditions. If indicated, the physician may also perform gastric lavage, which involves washing out the stomach by instilling a liquid and subsequently aspirating both the liquid and gastric contents. After the aspiration procedure, the gastric tube may either be left in place for further treatment or removed, depending on the clinical situation and physician's judgment.

1. Indications

The procedure described by CPT® Code 43753 is indicated for various medical conditions that necessitate the removal of gastric contents or the administration of therapeutic interventions. The following are specific indications for performing gastric intubation and aspiration:

  • Gastrointestinal Hemorrhage - This procedure is often performed in cases of gastrointestinal bleeding to remove blood and other contents from the stomach, which can help in diagnosing the source of the hemorrhage and in managing the patient's condition.
  • Gastric Decompression - In situations where there is a blockage or obstruction in the gastrointestinal tract, gastric intubation can relieve pressure by removing excess gas and fluid from the stomach.
  • Poisoning or Overdose - Gastric aspiration may be indicated in cases of poisoning or drug overdose to remove toxic substances from the stomach before they can be absorbed into the bloodstream.
  • Gastric Lavage - This procedure may be performed to wash out the stomach in cases of ingestion of harmful substances, allowing for the removal of potentially dangerous materials.

2. Procedure

The procedure for gastric intubation and aspiration involves several critical steps to ensure safety and effectiveness. Each step is outlined below:

  • Step 1: Patient Preparation - The patient is positioned comfortably, typically in a semi-reclined position, to facilitate the insertion of the gastric tube. The physician assesses the patient's nostrils to determine which one is more patent for tube insertion.
  • Step 2: Anesthesia Application - Viscous lidocaine is instilled into the selected nostril to provide local anesthesia, minimizing discomfort during the procedure. This step is crucial for patient comfort and cooperation.
  • Step 3: Tube Measurement and Marking - The physician estimates the length of the tube required for proper placement in the stomach. This length is marked on the tube to guide insertion.
  • Step 4: Tube Insertion - The tube is gently inserted into the nostril and advanced through the nasopharynx. The patient may be asked to sip water to assist in guiding the tube through the oropharynx and esophagus into the stomach.
  • Step 5: Verification of Placement - Proper placement of the tube in the stomach is verified by either instilling air into the stomach and auscultating for a rush of air or by aspirating gastric contents to confirm that the tube is correctly positioned.
  • Step 6: Therapeutic Aspiration - Once the tube is confirmed to be in the correct position, the physician performs the therapeutic aspiration procedure, removing gastric contents as necessary for the patient's treatment.
  • Step 7: Gastric Lavage (if performed) - If indicated, the physician may instill a liquid into the stomach and then aspirate both the liquid and gastric contents to wash out the stomach.
  • Step 8: Post-Procedure Management - After the aspiration procedure, the gastric tube may be left in place for further treatment or removed, depending on the clinical situation and the physician's assessment.

3. Post-Procedure

Following the gastric intubation and aspiration procedure, the patient may require monitoring for any adverse effects or complications. The physician will assess the patient's condition and determine if further interventions are necessary. If the gastric tube is left in place, the healthcare team will ensure that it is properly secured and that the patient is comfortable. Instructions regarding the care of the tube and any follow-up appointments will be provided to the patient. Additionally, the physician will document the procedure, including the indications, findings, and any complications encountered during the process, to ensure comprehensive medical records and facilitate ongoing patient care.

59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
GC This service has been performed in part by a resident under the direction of a teaching physician
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
