Ostomy skin barrier, liquid (spray, brush, etc.), per oz

HCPCS code

Name of the Procedure:

Ostomy Skin Barrier Application - Liquid Form (Spray, Brush, etc.) Technical Term: Application of Ostomy Skin Barrier (HCPCS Code: A4369)


The procedure involves applying a liquid skin barrier to the area around an ostomy. This barrier helps to protect the skin from irritation caused by ostomy output.


Ostomy skin barriers are used to protect the peristomal skin from irritation, infection, and damage caused by exposure to ostomy effluent. The goal is to maintain healthy skin around the ostomy site, ensuring that ostomy appliances adhere properly and reducing discomfort for the patient.


  • Presence of an ostomy (e.g., colostomy, ileostomy, urostomy)
  • Skin irritation or damage around the ostomy site
  • Difficulty achieving proper adhesion of ostomy appliances due to moisture or irregular skin surfaces


  • Cleanse the peristomal area with a mild soap and water
  • Pat the area dry using a clean cloth
  • Ensure the skin is free from any oils or lotions that could impede adhesion

Procedure Description

  1. Choose the appropriate liquid skin barrier (spray, brush, or other applicator).
  2. Apply the liquid skin barrier uniformly to the cleaned and dried peristomal skin.
  3. Allow the liquid to dry completely, forming a protective film.
  4. Proceed with attaching the ostomy appliance as usual.

Tools, equipment, or technology used: Liquid skin barrier in a spray, brush, or other dispensing format.

Anesthesia or sedation: None required.


The application process typically takes about 5 to 10 minutes, including drying time.


The procedure can be performed in various settings, including:

  • Home care
  • Outpatient clinic
  • Hospital setting


Usually, a trained healthcare professional such as a nurse or an ostomy specialist instructs the patient initially. Patients or caregivers typically perform the application thereafter.

Risks and Complications

  • Allergic reaction to the liquid skin barrier
  • Skin irritation if the barrier isn't allowed to dry properly
  • Non-adhesion of the ostomy appliance if applied incorrectly


  • Protection of peristomal skin from irritation and damage
  • Improved adhesion of ostomy appliances
  • Enhanced comfort and quality of life


No specific recovery time is needed. The patient can resume normal activities immediately after the procedure. Follow-up care typically involves routine monitoring of the skin condition around the ostomy site and adjustment of products as needed.


  • Use of stoma powder or paste
  • Barrier rings or seals
  • Adhesive tapes designed for ostomy care

Pros and cons vary with the particular needs and preferences of the patient.

Patient Experience

During the application, the patient may feel a cool or moist sensation from the liquid barrier, but it is generally free from discomfort. Post-application, any irritation from effluent should be reduced, improving overall comfort. Pain management isn’t typically necessary for this procedure, but maintaining skin integrity is crucial for ongoing comfort.
