Official Description

Gastrotomy; with exploration or foreign body removal

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 43500 refers to a gastrotomy, which is a surgical operation involving an incision into the stomach. This procedure is primarily performed for two main purposes: to explore the stomach for diagnostic reasons or to remove a foreign body that may be obstructing or causing issues within the stomach. During a gastrotomy, the surgeon makes an incision in the abdominal wall to access the stomach, allowing for direct visualization and examination of the stomach's inner lining. The stomach wall is then incised to provide access to the stomach's lumen, where the physician can inspect for any abnormalities such as lesions, ulcers, or signs of disease. If a foreign object is identified, it is carefully extracted, and the stomach is thoroughly inspected to ensure there are no injuries or additional complications. After the necessary interventions are completed, the stomach is sutured closed, and the surgical site is irrigated to prevent infection. Finally, the layers of the abdominal wall, including muscle and skin, are closed in a meticulous, layered manner to promote optimal healing and recovery.

1. Indications

The gastrotomy procedure described by CPT® Code 43500 is indicated for specific clinical situations where direct access to the stomach is necessary. The following are the primary indications for performing this procedure:

  • Exploration of the Stomach This procedure is indicated when there is a need to visually inspect the stomach for abnormalities, such as tumors, ulcers, or other pathological conditions that may not be identifiable through non-invasive imaging techniques.
  • Foreign Body Removal A gastrotomy is performed when a foreign object is suspected to be lodged in the stomach, causing obstruction or potential injury. This may include items ingested accidentally, such as coins, toys, or other non-food objects.

2. Procedure

The procedure for a gastrotomy with exploration or foreign body removal involves several critical steps, each essential for ensuring the safety and effectiveness of the operation. The following outlines the procedural steps:

  • Step 1: Anesthesia Administration Prior to the procedure, the patient is placed under general anesthesia to ensure they are unconscious and pain-free during the surgery. This is a standard practice for abdominal surgeries to facilitate a safe and controlled environment for the surgeon.
  • Step 2: Abdominal Incision The surgeon makes a careful incision in the abdominal wall, typically in the midline or another appropriate location, to gain access to the abdominal cavity. This incision is made with precision to minimize trauma to surrounding tissues.
  • Step 3: Exposure of the Stomach Once the abdominal cavity is accessed, the surgeon identifies and exposes the stomach. This may involve retracting surrounding organs and tissues to provide a clear view of the stomach for further examination.
  • Step 4: Incision of the Stomach Wall The surgeon then incises the stomach wall to access the inner lumen. This step is critical for allowing direct visualization of the stomach's interior, where any abnormalities can be assessed.
  • Step 5: Inspection and Intervention The inner lumen of the stomach is visually inspected for any signs of disease or injury. If a foreign body is present, it is carefully removed during this step. The surgeon also checks for any potential damage to the stomach lining that may require additional intervention.
  • Step 6: Closure of the Stomach After the necessary procedures are completed, the stomach is closed using sutures or staples. This step is vital to restore the integrity of the stomach and prevent leakage of gastric contents.
  • Step 7: Irrigation and Closure of the Surgical Wound The surgical site is irrigated to cleanse the area and reduce the risk of infection. Finally, the layers of the abdominal wall, including muscle and skin, are closed in a layered fashion to promote optimal healing.

3. Post-Procedure

After the gastrotomy procedure, patients are typically monitored in a recovery area until the effects of anesthesia wear off. Post-operative care includes managing pain, monitoring for any signs of complications such as infection or leakage from the stomach, and ensuring the patient can tolerate oral intake as they recover. The healthcare team will provide specific instructions regarding diet, activity restrictions, and follow-up appointments to assess healing and recovery progress. It is essential for patients to adhere to these guidelines to facilitate a smooth recovery process.

22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
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.
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.
62 Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate.
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.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
