Official Description

Laparoscopy, surgical; colectomy, partial, with anastomosis

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 44204 refers to a surgical procedure known as a partial colectomy performed via laparoscopy, which is a minimally invasive surgical technique. In this procedure, a small incision is made near the umbilicus, allowing for the insertion of a trocar, which is a surgical instrument used to create an entry point into the abdominal cavity. Once the trocar is in place, pneumoperitoneum is established, which involves inflating the abdominal cavity with gas to create a working space for the surgeon. Additional incisions are made in the upper and lower quadrants of the abdomen, where more trocars are inserted to facilitate the surgical process. During the procedure, the surgeon inspects the abdominal cavity to assess the condition of the colon. The specific segment of the colon that requires resection is carefully mobilized to enable its exteriorization, which means bringing the bowel segment outside the body for surgical intervention. The distal resection site is identified, and the colon is divided at this point. An incision at one of the lower abdominal trocar sites is then enlarged to allow the proximal segment of the colon to be brought through the abdominal wall. The bowel is exteriorized beyond the proximal resection site, and the proximal resection site is identified and resected using surgical clips and a harmonic scalpel, which is a device that uses ultrasonic vibrations to cut and coagulate tissue simultaneously. After the resection, the remaining segment of the bowel is returned to the abdominal cavity, and the incision made for exteriorization is closed. Finally, the distal and proximal segments of the colon are sutured or stapled together in a process known as anastomosis, which restores continuity to the gastrointestinal tract. This procedure is essential for treating various conditions affecting the colon, such as tumors or inflammatory diseases, while minimizing recovery time and complications associated with traditional open surgery.

1. Indications

The procedure described by CPT® Code 44204 is indicated for various conditions affecting the colon that may necessitate surgical intervention. These indications include:

  • Colon Tumors The presence of benign or malignant tumors in the colon that require resection to prevent further complications or progression of disease.
  • Diverticulitis Inflammation or infection of diverticula in the colon, which may lead to complications such as abscess formation or perforation.
  • Inflammatory Bowel Disease Conditions such as Crohn's disease or ulcerative colitis that may result in severe damage to the colon, necessitating partial removal.
  • Colonic Obstruction Blockages in the colon due to various causes, including strictures or tumors, that require surgical intervention to restore normal bowel function.

2. Procedure

The procedure for CPT® Code 44204 involves several critical steps that ensure the successful resection of the affected segment of the colon. The steps are as follows:

  • Step 1: Initial Incision and Trocar Insertion A small portal incision is made near the umbilicus, and a trocar is inserted to establish access to the abdominal cavity. This initial step is crucial for creating a working space for the laparoscopic instruments.
  • Step 2: Establishing Pneumoperitoneum Pneumoperitoneum is established by inflating the abdominal cavity with gas, which allows for better visualization and access to the internal organs during the procedure.
  • Step 3: Additional Incisions and Trocar Placement Additional portal incisions are made in the upper and lower quadrants of the abdomen, where more trocars are placed to facilitate the surgical procedure and provide access to the colon.
  • Step 4: Inspection of the Abdominal Cavity The surgeon inspects the abdominal cavity to assess the condition of the colon and identify the segment that requires resection.
  • Step 5: Mobilization of the Colon The segment of the colon to be resected is mobilized, allowing for its exteriorization. This step is essential for performing the resection safely.
  • Step 6: Identification and Division of the Distal Resection Site The distal resection site in the colon is identified, and the colon is divided at this point to remove the affected segment.
  • Step 7: Enlargement of the Incision The incision at one of the lower abdominal trocar sites is enlarged to facilitate the exteriorization of the proximal segment of the colon.
  • Step 8: Exteriorization of the Proximal Segment The proximal segment of the colon is brought through the enlarged incision in the abdominal wall and exteriorized beyond the proximal resection site.
  • Step 9: Resection of the Proximal Resection Site The proximal resection site is identified and resected using surgical clips and a harmonic scalpel, ensuring precise cutting and coagulation of the tissue.
  • Step 10: Closure of the Exteriorization Incision The remaining segment of the exteriorized bowel is returned to the abdominal cavity, and the incision made for exteriorization is closed securely.
  • Step 11: Anastomosis Finally, the distal and proximal segments of the colon are sutured or stapled together, completing the anastomosis and restoring continuity to the gastrointestinal tract.

3. Post-Procedure

After the completion of the laparoscopic partial colectomy, patients typically require monitoring for any immediate complications. Post-procedure care may include pain management, monitoring for signs of infection, and ensuring proper bowel function. Patients are often advised to gradually resume normal activities and follow a specific diet as they recover. The expected recovery time is generally shorter compared to open surgery, but individual recovery may vary based on the patient's overall health and the extent of the procedure performed. Follow-up appointments are essential to assess healing and address any concerns that may arise during the recovery process.

AS Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
GC This service has been performed in part by a resident under the direction of a teaching physician
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.
QZ Crna service: without medical direction by a physician
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).
25 Significant, separately identifiable evaluation and management service by the same physician or other qualified health care professional on the same day of the procedure or other service: it may be necessary to indicate that on the day a procedure or service identified by a cpt code was performed, the patient's condition required a significant, separately identifiable e/m service above and beyond the other service provided or beyond the usual preoperative and postoperative care associated with the procedure that was performed. a significant, separately identifiable e/m service is defined or substantiated by documentation that satisfies the relevant criteria for the respective e/m service to be reported (see evaluation and management services guidelines for instructions on determining level of e/m service). the e/m service may be prompted by the symptom or condition for which the procedure and/or service was provided. as such, different diagnoses are not required for reporting of the e/m services on the same date. this circumstance may be reported by adding modifier 25 to the appropriate level of e/m service. note: this modifier is not used to report an e/m service that resulted in a decision to perform surgery. see modifier 57 for significant, separately identifiable non-e/m services, see modifier 59.
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).
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).
54 Surgical care only: when 1 physician or other qualified health care professional performs a surgical procedure and another provides preoperative and/or postoperative management, surgical services may be identified by adding modifier 54 to the usual procedure number.
55 Postoperative management only: when 1 physician or other qualified health care professional performed the postoperative management and another performed the surgical procedure, the postoperative component may be identified by adding modifier 55 to the usual procedure number.
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.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
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.)
81 Minimum assistant surgeon: minimum surgical assistant services are identified by adding modifier 81 to the usual procedure number.
99 Multiple modifiers: under certain circumstances 2 or more modifiers may be necessary to completely delineate a service. in such situations modifier 99 should be added to the basic procedure, and other applicable modifiers may be listed as part of the description of the service.
