Official Description

Small intestinal endoscopy, enteroscopy beyond second portion of duodenum, not including ileum; with conversion of percutaneous gastrostomy tube to percutaneous jejunostomy tube

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 44373 refers to a specific medical procedure known as small intestinal endoscopy, particularly focusing on enteroscopy beyond the second portion of the duodenum, which does not include the ileum. This procedure involves the conversion of a percutaneous gastrostomy tube to a percutaneous jejunostomy tube. In simpler terms, it is an endoscopic examination of the small intestine that allows healthcare providers to visualize and assess the jejunum, which is the middle section of the small intestine, located after the duodenum. The jejunum plays a crucial role in nutrient absorption, and the procedure is often performed on patients who are unable to consume food or liquids orally due to various medical conditions. During the procedure, a percutaneous endoscopic jejunostomy (PEJ) tube is placed in the jejunum to provide nutritional support directly to the digestive system. The process begins with the administration of an anesthetic spray to numb the mouth and throat, followed by the insertion of a flexible fiberoptic endoscope. This endoscope is carefully advanced through the patient's mouth and into the gastrointestinal tract, allowing the physician to visualize the mucosal surfaces of the small intestine. The examination extends beyond the second portion of the duodenum, ensuring that any abnormalities in the jejunum can be identified and documented. In cases where a patient has an existing gastrostomy tube, this procedure allows for the conversion to a jejunostomy tube, which is often necessary when there are concerns about aspiration of stomach contents into the lungs. The conversion process involves the removal of the gastrostomy tube and the careful placement of a new feeding tube into the jejunum, ensuring that the patient continues to receive adequate nutrition while minimizing the risk of complications.

1. Indications

The procedure described by CPT® Code 44373 is indicated for patients who require nutritional support through a jejunostomy tube due to an inability to take food or liquids by mouth. The following conditions may warrant this procedure:

  • Inability to Swallow: Patients who have difficulty swallowing due to neurological disorders, structural abnormalities, or other medical conditions.
  • Chronic Aspiration: Individuals with a history of aspiration pneumonia or recurrent aspiration of stomach contents into the lungs, necessitating the conversion from a gastrostomy tube to a jejunostomy tube.
  • Gastrointestinal Disorders: Patients with conditions affecting the gastrointestinal tract that impair normal digestion and absorption of nutrients.
  • Long-term Nutritional Support: Patients requiring prolonged enteral feeding due to chronic illnesses or conditions that prevent oral intake.

2. Procedure

The procedure for CPT® Code 44373 involves several critical steps to ensure successful endoscopic examination and tube placement:

  • Step 1: Anesthesia Administration - The procedure begins with the application of an anesthetic spray to numb the patient's mouth and throat, facilitating the insertion of the endoscope without discomfort.
  • Step 2: Endoscope Insertion - A flexible fiberoptic endoscope is introduced into the patient's mouth and advanced through the esophagus. The physician guides the endoscope into the duodenum, ensuring it passes beyond the cricopharyngeal region.
  • Step 3: Visualization and Inspection - Once the endoscope reaches the small intestine, the mucosal surfaces are carefully inspected beyond the second portion of the duodenum. The physician looks for any abnormalities or issues that may require attention.
  • Step 4: Tube Conversion - If a gastrostomy tube is already in place, it is removed. An angiocatheter and guidewire are then inserted through the existing gastrostomy incision. Using endoscopic guidance, the catheter is navigated through the pylorus and into the jejunum, beyond the ligament of Treitz.
  • Step 5: Jejunostomy Tube Placement - After the angiocatheter is removed, a gastrojejunostomy (G-J) tube is advanced over the guidewire into the jejunum. This tube is designed to provide nutritional support directly into the jejunum.
  • Step 6: Securing the Tube - The G-J tube is secured internally with a bumper or balloon and externally with a bumper, flange, or other securing device to ensure stability and prevent dislodgment.

3. Post-Procedure

After the completion of the procedure, patients are typically monitored for any immediate complications or adverse reactions. It is essential to ensure that the jejunostomy tube is functioning correctly and that the patient is tolerating enteral feeding. Follow-up care may include instructions on tube maintenance, signs of infection, and dietary recommendations to optimize nutritional intake. Patients may also require regular assessments to monitor their nutritional status and adjust feeding protocols as necessary.

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).
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.
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.
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).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) 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.
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.)
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).
