Official Description

Incision and drainage of pilonidal cyst; complicated

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

A pilonidal cyst is a type of cyst that typically forms in the area just above the cleft of the buttocks. It is often filled with hair, skin debris, and other materials. When a pilonidal cyst becomes infected, it can lead to the formation of an abscess, which is a collection of pus that can cause significant discomfort and pain. In such cases, a surgical procedure known as incision and drainage is performed to alleviate the symptoms and treat the infection. During this procedure, the affected area is first cleansed, and a local anesthetic is administered to minimize discomfort. A straight or elliptical incision is then made to access the cyst and any associated abscess. The surgeon carefully opens any pockets of pus using blunt dissection techniques, allowing for effective drainage. Following the drainage, the surgeon removes any hair and debris present within the cyst, as well as the epithelial lining, which is typically accomplished through a process called curettage. It is important to note that CPT® Code 10080 is designated for a simple incision and drainage procedure that involves local wound care, while CPT® Code 10081 is specifically used for a complicated incision and drainage procedure, which may include the placement of a drain or packing the wound with gauze to promote healing and prevent further complications.

1. Indications

The procedure of incision and drainage of a pilonidal cyst is indicated in the following situations:

  • Infected Pilonidal Cyst The procedure is performed when a pilonidal cyst becomes infected, leading to the formation of an abscess that requires surgical intervention.
  • Presence of Fluctuance The presence of fluctuance, which indicates the accumulation of pus within the cyst, necessitates drainage to relieve pressure and pain.
  • Recurrent Symptoms Patients experiencing recurrent symptoms or complications related to a pilonidal cyst may require this procedure to prevent further issues.

2. Procedure

The procedure for incision and drainage of a complicated pilonidal cyst involves several key steps:

  • Preparation of the Area The skin surrounding the pilonidal cyst is thoroughly cleansed to reduce the risk of infection. This step is crucial for maintaining a sterile environment during the procedure.
  • Administration of Local Anesthetic A local anesthetic is injected into the area to ensure that the patient experiences minimal discomfort during the procedure. This allows the surgeon to perform the incision and drainage effectively without causing pain.
  • Incision Creation A straight or elliptical incision is made that spans the entire area of fluctuance. This incision is critical for accessing the cyst and any associated abscesses.
  • Blunt Dissection The surgeon uses blunt dissection techniques to open any pockets of pus within the cyst. This step is essential for ensuring that all infected material is adequately drained.
  • Drainage of Abscess The abscess is drained completely, allowing for the removal of pus and alleviating pressure in the affected area.
  • Removal of Hair and Debris Any hair and debris present within the cyst are removed to prevent future infections. This is an important part of the procedure to ensure thorough cleaning of the cyst.
  • Curettage of Epithelial Lining The epithelial lining of the cyst is removed through curettage, which helps to reduce the likelihood of recurrence by eliminating the cyst's internal structure.
  • Placement of Drain or Packing In cases classified as complicated, a drain may be placed, or the wound may be packed with gauze to facilitate proper healing and prevent fluid accumulation.

3. Post-Procedure

After the incision and drainage procedure, patients are typically monitored for any signs of complications. Post-procedure care may include instructions for wound care, such as keeping the area clean and dry, and changing dressings as needed. Patients may also be advised on pain management strategies and the importance of follow-up appointments to ensure proper healing. It is essential to monitor for any signs of infection, such as increased redness, swelling, or discharge from the incision site. If a drain has been placed, specific instructions regarding its care and maintenance will be provided to the patient. Overall, the expected recovery time may vary depending on the complexity of the procedure and the individual patient's health status.

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).
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.
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.
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.)
