The procedure described by CPT® Code 47300 refers to the marsupialization of a cyst or abscess located in the liver. This surgical intervention is specifically designed to treat fluid-filled sacs (cysts) or collections of pus (abscesses) that can develop within the liver tissue. The term 'marsupialization' indicates that the cyst or abscess is surgically opened and a pouch is created to facilitate the drainage of its contents, which may include fluid and debris. This approach helps to prevent the recurrence of the cyst or abscess by allowing continuous drainage. The procedure typically involves making an incision in the right subcostal area, which may extend into the left subcostal region or even up towards the xiphoid process, depending on the size and location of the cyst or abscess. During the operation, the surgeon transects the right rectus muscle and splits the oblique muscles to gain access to the liver. The medial portion of the left rectus muscle may also be transected to provide adequate exposure. Once the cyst or abscess is accessed, it is opened and drained, and the anterior wall of the cyst is resected. The remaining wall is carefully inspected for any biliary orifices, which are sutured to prevent bile leakage. Additionally, any biliary vessels that drain into the cyst or abscess are ligated to minimize complications. Finally, the cut edges of the remaining wall are sutured back to the adjacent skin edges, creating a pouch that remains open to allow for ongoing drainage and healing.

The marsupialization of a cyst or abscess of the liver, as described by CPT® Code 47300, is indicated for specific conditions that necessitate intervention. These indications include:
The procedure for marsupialization of a cyst or abscess of the liver involves several critical steps, each designed to ensure effective drainage and minimize the risk of recurrence. The steps are as follows:
After the marsupialization procedure, patients typically require monitoring for any signs of complications, such as infection or excessive bleeding. Post-procedure care may include pain management, wound care, and follow-up imaging to ensure proper healing and drainage. Patients are often advised to avoid strenuous activities during the initial recovery period to facilitate healing. The open pouch created during the procedure allows for ongoing drainage, which is essential for recovery. Regular follow-up appointments may be necessary to assess the site and ensure that the cyst or abscess does not recur.

| 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). | 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. | 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). | AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery | CR | Catastrophe/disaster related | GC | This service has been performed in part by a resident under the direction of a teaching physician | TC | Technical component; under certain circumstances, a charge may be made for the technical component alone; under those circumstances the technical component charge is identified by adding modifier 'tc' to the usual procedure number; technical component charges are institutional charges and not billed separately by physicians; however, portable x-ray suppliers only bill for technical component and should utilize modifier tc; the charge data from portable x-ray suppliers will then be used to build customary and prevailing profiles | XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service |
