Name of the Procedure:

Oasis Wound Matrix, per square centimeter (HCPCS Code: Q4102)

• Common Name(s): Oasis Wound Matrix
• Medical Term: Extracellular matrix wound dressing

Summary

The Oasis Wound Matrix procedure involves applying a specialized wound dressing derived from porcine small intestinal submucosa to a patient's wound. This material supports the body's natural healing processes by providing a scaffold for cell growth and tissue regeneration.

Purpose

• Medical Conditions: Chronic wounds, diabetic ulcers, venous ulcers, pressure ulcers, and other hard-to-heal wounds.
• Goals: Promote faster wound healing, reduce the risk of infection, and improve overall wound closure.

Indications

• Conditions: Non-healing chronic wounds, ulcers, and wounds that have not responded to conventional treatments.
• Patient Criteria: Patients with appropriate wound types who have no known allergies to porcine products.

Preparation

• Pre-procedure Instructions: Clean the wound area thoroughly. No need for fasting or significant medication adjustments.
• Diagnostic Tests: Wound assessment, including size, depth, and infection status.

Procedure Description

1. Wound Preparation: Clean and debride the wound.
2. Fitting the Matrix: Trim the Oasis Wound Matrix to fit the wound size and shape.
3. Application: Apply the matrix directly to the wound bed.
4. Securing: Cover with a secondary dressing to keep the matrix in place.
5. Monitoring: Regularly check and replace the dressing as needed.

• Tools: Sterile scissors, saline solution, secondary dressings.
• Anesthesia: Typically none required; local anesthesia may be used for patient comfort during debridement.

Duration

The initial application takes about 20-30 minutes.

Setting

Primarily performed in outpatient clinics, wound care centers, or sometimes in a hospital setting for severe cases.

Personnel

• Wound care specialists or nurses specializing in wound management.
• Physicians or surgeons if the wound is particularly complex.

Risks and Complications

• Common Risks: Mild discomfort at the application site, minor irritation.
• Rare Risks: Allergic reaction to porcine material, infection if the wound care protocol is not followed.
• Management: Standard protocols for allergy management and infection control.

Benefits

• Expected Benefits: Accelerated and improved wound healing.
• Timeline: Positive effects can be typically seen within a few weeks of consistent application.

Recovery

• Post-procedure Care: Keep the wound clean and protected. Avoid unnecessary pressure or trauma to the wound area.
• Recovery Time: Varies; generally, several weeks to months, depending on the wound type and severity.
• Restrictions: Minimize activities that could disrupt the healing process. Regular follow-up appointments for wound assessment and dressing changes.

Alternatives

• Other Treatments: Traditional dressings, synthetic wound dressings, negative pressure wound therapy, advanced wound care techniques like skin grafts.
• Pros & Cons: Traditional dressings are cheaper but less effective for chronic wounds. Advanced methods like skin grafts may be more invasive and costly.

Patient Experience

• During the Procedure: Mild discomfort during wound cleaning and debridement, generally well-tolerated.
• After the Procedure: Minimal pain; itching or discomfort around the wound area might be managed with over-the-counter pain relievers or prescribed medications.
