Official Description

Excision or destruction, open, intra-abdominal tumors, cysts or endometriomas, 1 or more peritoneal, mesenteric, or retroperitoneal primary or secondary tumors; largest tumor 5 cm diameter or less

Common Language Description

The procedure described by CPT® Code 49203 involves the open excision or destruction of intra-abdominal tumors, cysts, or endometriomas. This surgical intervention is applicable to one or more tumors located in the peritoneal, mesenteric, or retroperitoneal areas. The tumors addressed in this procedure can vary in nature; they may be benign, such as endometriomas or benign cystic mesotheliomas, or malignant, including adenocarcinomas, malignant mesotheliomas, desmoplastic small cell tumors, or liposarcomas. The procedure allows for the complete excision of these tumors or their destruction through methods such as electrocautery or laser ablation, which is also referred to as surgical ablation. The surgical approach begins with an incision in the abdomen, allowing access to the peritoneum, which is then carefully incised to avoid damaging surrounding organs, including the bowel. Once the peritoneal cavity is opened, any adhesions are dissected to expose the abdominal viscera. A thorough exploration of the abdominal cavity is conducted, both visually and through palpation, to identify all masses and abnormalities. The size, location, and extent of the largest tumor, which must be 5 cm in diameter or less for this code to apply, are documented. The excision or destruction of the tumor is performed, and this process is repeated for any additional tumors present. For retroperitoneal tumors, similar techniques are employed, with particular attention paid to protecting the kidneys, ureters, and renal vessels during the procedure. It is important to note that different CPT codes are designated for tumors of varying sizes, with 49204 applicable for tumors measuring 5.1 to 10.0 cm and 49205 for those exceeding 10.0 cm in diameter.

1. Indications

The procedure described by CPT® Code 49203 is indicated for the excision or destruction of intra-abdominal tumors, cysts, or endometriomas. The specific indications for this procedure include:

  • Intra-abdominal tumors - These may include both benign and malignant growths that require surgical intervention.
  • Cysts - Fluid-filled sacs that may cause discomfort or complications and need to be removed.
  • Endometriomas - Cysts associated with endometriosis that can lead to pain and other symptoms.
  • Primary tumors - Tumors that originate in the abdominal cavity.
  • Secondary tumors - Tumors that have metastasized to the abdominal cavity from other sites in the body.

2. Procedure

The procedure for CPT® Code 49203 involves several critical steps to ensure the effective excision or destruction of the tumors present in the abdominal cavity. The steps are as follows:

  • Step 1: Incision - An incision is made in the abdomen to access the peritoneum. This incision is carefully planned to minimize trauma to surrounding tissues.
  • Step 2: Accessing the Peritoneum - The peritoneum is grasped, elevated, and incised, ensuring that care is taken to avoid injury to the bowel and other internal organs during this process.
  • Step 3: Opening the Peritoneal Cavity - Once the peritoneum is incised, the peritoneal cavity is opened, allowing for further exploration and intervention.
  • Step 4: Dissecting Adhesions - Any adhesions present are dissected to expose the abdominal viscera fully, facilitating a comprehensive examination of the area.
  • Step 5: Exploration - The entire abdominal cavity is explored visually and by palpation to identify all masses and abnormalities, ensuring that no tumors are overlooked.
  • Step 6: Tumor Assessment - The location, size, and extent of the first identified tumor are documented, which is crucial for determining the appropriate coding and treatment approach.
  • Step 7: Tumor Excision or Destruction - The identified tumor is either excised or destroyed using electrocautery or laser techniques. This step may be repeated for any additional tumors present in the abdominal cavity.
  • Step 8: Retroperitoneal Tumor Management - For any retroperitoneal tumors, similar techniques are employed, with careful attention to avoid injury to the kidneys, ureters, and renal vessels during the procedure.

3. Post-Procedure

Post-procedure care following the excision or destruction of intra-abdominal tumors involves monitoring the patient for any complications that may arise from the surgery. Patients are typically observed for signs of infection, bleeding, or any adverse reactions to anesthesia. Recovery may vary depending on the extent of the surgery and the patient's overall health. Patients may be advised to follow specific guidelines regarding activity levels, dietary restrictions, and wound care to promote healing. Follow-up appointments are essential to assess the surgical site and ensure that there are no complications or recurrences of the tumors. Additionally, further imaging or diagnostic tests may be required to monitor the patient's condition and evaluate the success of the procedure.

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).
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.
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).
95 Synchronous telemedicine service rendered via a real-time interactive audio and video telecommunications system: synchronous telemedicine service is defined as a real-time interaction between a physician or other qualified health care professional and a patient who is located at a distant site from the physician or other qualified health care professional. the totality of the communication of information exchanged between the physician or other qualified health care professional and the patient during the course of the synchronous telemedicine service must be of an amount and nature that would be sufficient to meet the key components and/or requirements of the same service when rendered via a face-to-face interaction. modifier 95 may only be appended to the services listed in appendix p. appendix p is the list of cpt codes for services that are typically performed face-to-face, but may be rendered via a real-time (synchronous) interactive audio and video telecommunications system.
