Official Description

Incision and drainage of soft tissue abscess, subfascial (ie, involves the soft tissue below the deep fascia)

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 20005 refers to the procedure of incision and drainage of a soft tissue abscess that is located subfascially, meaning it involves the soft tissue situated beneath the deep fascia. This procedure is typically performed when an abscess, which is a localized collection of pus, forms in the soft tissues of the body and requires surgical intervention to alleviate pain, prevent further infection, and promote healing. The process begins with making an incision over the area of the abscess, allowing access to the underlying tissue. The use of forceps or a closed blunt hemostat is essential for safely opening the incision and facilitating the drainage of purulent material, which is the thick fluid that accumulates in the abscess. During the procedure, specimens may be collected for culture and sensitivity testing, which helps in identifying the specific bacteria causing the infection and determining the most effective antibiotic treatment. Additionally, the surgeon will insert a finger through the incision to break up any pockets of pus, ensuring thorough evacuation of the abscess. The cavity is then irrigated with sterile saline to cleanse the area, and a drain may be placed or the cavity packed with gauze to promote further drainage and healing.

1. Indications

The procedure described by CPT® Code 20005 is indicated for the treatment of soft tissue abscesses that are located beneath the deep fascia. The following conditions may warrant this surgical intervention:

  • Soft Tissue Abscess The presence of a localized collection of pus in the soft tissues, which may cause pain, swelling, and potential systemic infection.
  • Infection Signs of infection such as redness, warmth, and tenderness in the affected area, indicating the need for drainage to prevent further complications.
  • Failure of Conservative Treatment Situations where conservative management, such as antibiotics or warm compresses, has not resolved the abscess, necessitating surgical intervention.

2. Procedure

The procedure for incision and drainage of a subfascial soft tissue abscess involves several critical steps to ensure effective treatment and patient safety:

  • Step 1: Preparation The patient is positioned appropriately, and the area over the abscess is cleaned and sterilized to minimize the risk of infection during the procedure.
  • Step 2: Incision A surgical incision is made directly over the abscessed area, extending down to the subfascial tissue. This incision allows access to the infected area beneath the skin.
  • Step 3: Opening the Abscess Using forceps or a closed blunt hemostat, the incision is carefully opened to facilitate the drainage of purulent material. This step is crucial for relieving pressure and pain associated with the abscess.
  • Step 4: Drainage A finger is inserted through the incision to break up and evacuate any pockets of pus that may be present within the abscess cavity. This thorough evacuation is essential for effective treatment.
  • Step 5: Irrigation The abscess cavity is copiously irrigated with sterile saline to cleanse the area and remove any remaining debris or infectious material.
  • Step 6: Drain Placement or Packing Depending on the size and nature of the abscess, a drain may be placed to allow for continued drainage, or the cavity may be packed with gauze to promote healing and prevent re-accumulation of pus.

3. Post-Procedure

After the procedure, the patient will require monitoring for any signs of complications, such as increased pain, fever, or persistent drainage. Instructions for wound care will be provided, including how to keep the area clean and dry. If a drain is placed, specific guidelines on how to care for the drain and when to return for follow-up will be given. Patients may also be prescribed antibiotics to prevent infection and manage any residual symptoms. Follow-up appointments are essential to assess healing and determine if further intervention is necessary.
