Name of the Procedure:

Ostomy Skin Barrier, Solid, 4 x 4 or Equivalent, Extended Wear, Without Built-In Convexity (HCPCS Code: A4385)


An ostomy skin barrier is a medical device used by individuals with an ostomy, a surgically created opening on the abdomen for the discharge of bodily waste. The barrier protects the skin around the stoma (the opening) from irritation and breakdown, ensuring a secure fit for the ostomy pouch.


The ostomy skin barrier addresses issues related to skin protection and waste collection for individuals with an ostomy. It aims to prevent skin irritation and provide a secure attachment for the ostomy pouch, which collects waste material.


  • Patients who have undergone an ostomy procedure.
  • Individuals experiencing skin irritation or leakage around their stoma.
  • Patients who require an extended wear barrier for longer periods of protection.


  • Clean and dry the peristomal skin (skin around the stoma) thoroughly.
  • Ensure all previous adhesive residues are removed.
  • If necessary, trim or shape the barrier to fit the stoma opening precisely.

Procedure Description

  1. Clean and dry the skin around the stoma.
  2. Remove the protective backing from the barrier adhesive.
  3. Center the barrier over the stoma, ensuring a snug fit without wrinkles.
  4. Press down firmly to ensure it adheres properly.
  5. Attach the ostomy pouch to the barrier.

Tools and Equipment:

  • Ostomy skin barrier (4x4 or equivalent, extended wear, without built-in convexity)
  • Cleaning supplies (mild soap and water)
  • Scissors (if trimming the barrier is required)

No anesthesia or sedation is necessary for this procedure.


The application of the ostomy skin barrier typically takes about 5-10 minutes.


This procedure can be performed at home or in an outpatient clinic.


  • The patient themselves or a caregiver.
  • Healthcare professionals (e.g., ostomy nurses) for initial training and support.

Risks and Complications

  • Skin irritation or allergic reaction to the adhesive.
  • Barrier leakage, leading to skin irritation or infection.
  • Difficulty in achieving a proper fit, especially in patients with an irregular stoma.


  • Provides a protective layer to maintain skin integrity.
  • Ensures a secure attachment for the ostomy pouch.
  • Long-lasting protection which may reduce the frequency of changes.


Post-procedure care includes regular monitoring of the skin for signs of irritation or breakdown. The barrier typically needs to be changed every few days or as directed by a healthcare provider. Follow-up appointments may be needed to address any issues or complications.


  • Other types of skin barriers, such as those with built-in convexity or different sizes.
  • Ostomy belts or additional adhesive products to secure the pouch.
  • Different types of ostomy pouches designed for specific needs.

Pros and Cons:

  • Alternative barriers may provide a better fit or additional comfort.
  • Some alternatives may require more frequent changes or different handling techniques.

Patient Experience

Patients can expect minimal discomfort during the application of the barrier. Properly fitting barriers can enhance comfort and confidence in managing the ostomy. Any initial discomfort typically lessens as the patient becomes familiar with the routine. For pain management or skin irritation, healthcare providers can offer topical treatments or recommend alternative products.
