Official Description

Incision and drainage below fascia, with or without tendon sheath involvement, foot; single bursal space

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 28002 involves an incision and drainage operation performed below the fascia of the foot, specifically targeting a single bursal space. A bursa is a small fluid-filled sac that acts as a cushion between bones and soft tissues, reducing friction and allowing for smooth movement. In cases where a bursa becomes infected, it can lead to significant pain and swelling, necessitating surgical intervention. During this procedure, the surgeon makes an incision in the skin directly over the infected bursa, allowing access to the underlying tissues. The soft tissues are carefully dissected to expose the fascia, which is then incised to reach the infected area. The tendon sheath, which surrounds the tendons in the foot, is also inspected to assess any involvement in the infection. The infected bursal space is opened using a scalpel, and the contents are drained to alleviate pressure and remove pus or other infectious materials. Following drainage, the area is typically flushed with saline or an antibiotic solution to help clear any remaining infection. Depending on the extent of the procedure and the surgeon's assessment, drains may be placed to facilitate further drainage if necessary. The incision may be closed in layers to promote healing or packed with gauze and left open to allow for continued drainage and healing. This procedure is specifically coded as 28002 for cases involving a single bursal space, while 28003 is used for incision and drainage of multiple areas in the foot.

1. Indications

The procedure described by CPT® Code 28002 is indicated for the treatment of conditions involving an infected bursa in the foot. The following are specific indications for performing this procedure:

  • Infected Bursa The primary indication for this procedure is the presence of an infection in a bursal space of the foot, which can cause pain, swelling, and limited mobility.
  • Abscess Formation The procedure may also be indicated in cases where an abscess has formed within the bursa, requiring drainage to relieve pressure and prevent further complications.
  • Persistent Symptoms Patients who experience persistent symptoms despite conservative treatment measures, such as rest, ice, and antibiotics, may require this surgical intervention to resolve the infection.

2. Procedure

The procedure for CPT® Code 28002 involves several critical steps to ensure effective drainage of the infected bursal space:

  • Step 1: Incision The surgeon begins by making a precise incision in the skin over the infected bursa. This incision is strategically placed to provide optimal access to the affected area while minimizing damage to surrounding tissues.
  • Step 2: Dissection Following the incision, the surgeon carefully dissects the soft tissues to expose the underlying fascia. This step is crucial for accessing the bursal space and requires meticulous technique to avoid injury to nearby structures.
  • Step 3: Fascia Incision Once the fascia is exposed, the surgeon incises it to gain entry into the bursal space. This allows for direct access to the infected area, facilitating effective drainage.
  • Step 4: Inspection of Tendon Sheath The tendon sheath, which may be involved in the infection, is then exposed and inspected. This step is important to assess the extent of the infection and determine if further intervention is necessary.
  • Step 5: Drainage of Infected Bursal Space The infected bursal space is opened with a scalpel, allowing the contents, including pus and infected fluid, to be drained. This step is essential for relieving pressure and promoting healing.
  • Step 6: Flushing the Site After drainage, the surgical site is flushed with saline or an antibiotic solution. This helps to clear any residual infection and prepares the area for healing.
  • Step 7: Placement of Drains If necessary, drains may be placed in the bursal space to facilitate ongoing drainage and prevent fluid accumulation, which can lead to further complications.
  • Step 8: Closure of Incision Finally, the incision may be closed in layers to promote optimal healing, or it may be packed with gauze and left open, depending on the surgeon's assessment and the extent of the infection.

3. Post-Procedure

After the procedure, patients can expect specific post-operative care and considerations. The surgical site will require monitoring for signs of infection, such as increased redness, swelling, or discharge. Patients may be advised to keep the area clean and dry, and to follow any specific wound care instructions provided by the surgeon. Pain management may be necessary, and patients should be informed about the appropriate use of analgesics. Follow-up appointments will be scheduled to assess healing and determine if further intervention is needed. If drains were placed, instructions on how to care for them and when they will be removed will also be provided. Overall, the recovery process will vary depending on the individual patient's condition and the extent of the procedure performed.
