HCPCS code

Name of the Procedure:

Skin Barrier Application; Solid, 6 x 6 inch or Equivalent (HCPCS Code A5121)


This procedure involves applying a solid skin barrier that measures 6 x 6 inches or an equivalent size. The barrier serves to protect the skin from external factors and is commonly used in wound care and ostomy management.


The skin barrier protects sensitive skin from adhesives, moisture, and harmful substances. It is crucial for patients with stomas, preventing irritation and infection around the stoma site. The goal is to maintain skin integrity and promote healing.


  • Patients with stomas (colostomy, ileostomy, urostomy).
  • Individuals with wounds requiring protection from external contaminants.
  • Those experiencing skin irritation or breakdown due to adhesives or moisture.


  • Clean the skin area where the barrier will be applied.
  • Ensure the skin is dry and free of any creams or lotions.
  • No specific fasting or medication adjustments are required.

Procedure Description

  1. Cleaning and Drying: The skin area is first cleaned and thoroughly dried.
  2. Measuring and Cutting: The solid skin barrier is measured and, if necessary, cut to fit the specific area.
  3. Application: The barrier is carefully applied to the skin, ensuring it adheres well and covers the intended area.
  4. Securing the Barrier: If used around a stoma, an ostomy appliance may then be attached over the barrier.
Tools and Equipment
  • Solid skin barrier (6 x 6 inches or equivalent).
  • Scissors (for trimming the barrier if needed).
Anesthesia or Sedation
  • Not applicable.


The application process typically takes 10-15 minutes.


This procedure can be performed in various settings, including hospitals, outpatient clinics, home care, and nursing facilities.


  • Registered Nurses (RNs).
  • Ostomy or Wound Care Specialists.

Risks and Complications

  • Minor skin irritation or allergic reaction to the barrier material.
  • Improper application can lead to decreased effectiveness.
  • Leakage or dislocation around stoma sites if not correctly applied.


  • Protection of the skin from irritation, infection, and breakdown.
  • Enhanced comfort and quality of life, especially for individuals with stomas.
  • Immediate protective effects upon application.


  • Minimal downtime; patients can resume normal activities immediately.
  • Regular monitoring and maintenance of the skin barrier might be necessary.


  • Liquid skin barriers.
  • Hydrocolloid dressings.
  • Foam dressings.

    Pros and Cons of Alternatives
  • Liquid skin barriers: Easier to apply but may need frequent reapplication.
  • Hydrocolloid dressings: Effective but thicker and less conforming to the skin.
  • Foam dressings: Provide additional cushioning but may not adhere as well.

Patient Experience
