Collagen-Based Wound Filler, Gel/Paste, per Gram of Collagen (A6011)

Name of the Procedure:

Commonly referred to as "Collagen-Based Wound Filler." The medical codename for this procedure is HCPCS A6011.


A Collagen-Based Wound Filler is used to treat wounds by applying a gel or paste composed of collagen directly to the wound site. This filler aids in wound healing by providing a scaffold for new tissue growth and helps absorb excess wound exudate.


The procedure aims to assist the body in healing wounds more effectively by creating a conducive environment for tissue regeneration and managing wound moisture.


The procedure is indicated for a variety of wound types including:

  • Chronic non-healing wounds
  • Diabetic ulcers
  • Pressure ulcers
  • Venous ulcers
  • Surgical wounds

Patients with these conditions are often suitable candidates for this treatment, especially when traditional wound healing methods have been ineffective.


  • Pre-Procedure Instructions: Depending on the wound's location and type, patients may be advised to keep the area clean and avoid certain medications that might interfere with clotting.
  • Diagnostic Assessments: Wound assessment to determine size, depth, and the presence of infection; sometimes, additional imaging or microbiological cultures might be required.

Procedure Description

  1. Cleaning the Wound: The healthcare provider thoroughly cleans the wound to remove any debris or non-viable tissue.
  2. Application of Collagen Filler: The collagen gel or paste is then carefully applied to the wound site. The amount used corresponds to the wound's size and exudate level.
  3. Covering the Wound: After application, the wound is usually covered with a secondary dressing to protect the area and maintain moisture levels.
  4. Tools and Equipment: Items commonly used include saline for cleaning, applicators for the gel/paste, and appropriate secondary dressings.
  5. Anesthesia: Typically, local anesthesia is not required unless extensive debridement (removal of dead tissue) is necessary, in which case local anesthetic may be used.


The application process generally takes about 15-30 minutes, depending on the wound's complexity.


The procedure is typically performed in an outpatient clinic, wound care center, or occasionally in a hospital setting if the patient is already admitted.


  • Primary: Wound care specialists, nurses, or in some cases, physicians.
  • Supportive: Medical assistants or other healthcare staff may assist.

Risks and Complications

  • Common: Mild irritation or allergic reaction at the application site.
  • Rare: Infection or worsening of the wound, which would require more intensive medical intervention.


  • Expected Benefits: Promotes faster and more effective wound healing by providing necessary cells with a scaffold for new tissue formation.
  • Timeline for Benefits: Many patients start seeing improvements within a few weeks, though this varies by wound type and severity.


  • Post-Procedure Care: Regular wound cleaning and dressing changes as instructed by the healthcare provider.
  • Recovery Time: Patients should expect to follow up regularly for wound assessments and might require several applications until the wound fully heals.
  • Restrictions: Avoid strenuous activities that might impact the wound area, keep the wound site clean and dry as advised.


  • Other Treatment Options: Traditional wound dressings, vacuum-assisted closure therapy, skin grafts, and other advanced wound care products.
  • Pros and Cons: Collagen fillers are often more effective for non-healing wounds but might be more costly compared to basic dressings.

Patient Experience

Patients might feel slight discomfort or a mild sensation during the application. Post-procedure, most patients experience minimal pain which can be managed with standard analgesics as recommended. In general, the procedure is well-tolerated with manageable discomfort levels.
