Collagen advanced wound care dressings are reimbursed by Medicare Part B, Medicaid, HMO’s, and other primary payors. Following Medicare Part B and third-party payer guidelines are critical in paid reimbursement claims. Medicare Part B will generally pay 80% of the Medicare-approved amount after paid deductible. Third-party payers can vary by State, plan type, and Provider.

Physician Guidelines


To deliver evidence-based advanced wound care while utilizing established and developed medical standards to optimize wound healing outcomes:

  • Weekly wound assessment should include:

    1. Wound location
    2. Wound type – pressure, diabetic, venous, arterial, surgical, trauma, other.
    3. Depth of tissue involvement – partial-thickness, full-thickness, undermining, tunneling, exposed structure.
    4. Exudate amount – scant, minimal, moderate, heavy, copious
    5. Exudate consistency – color, odor
    6. Wound bed tissue type(s) or color(s)
    7. Periwound, wound edges, and surrounding skin
    8. Pain level – location, duration, frequency
  • Use appropriate primary dressing, collagen formulation (KollagenTM particles, sheet, or gel) based on wound assessment.
  • Secondary dressings are used as a cover dressing: e.g., transparent, gauze, abdominal pad, foam, super-absorbent pad, hydrocolloid, Unna's boot, and multi-layer wrap. 
  • Dressing size is determined by wound measurements that may or may not include periwound. A larger dressing may be used if the clinical rationale supports product size.
  • Physician progress note/wound note must substantiate advanced wound care products and frequency of change.
  • Wound photos can be used as an adjunct to written documentation.  Always follow your policy and procedures.
  • Physician detailed written order must be signed and dated for each product billed, including # of dressings and directions for us. Orders may be placed every 30 days per Medicare Part B guidelines.
  • The physician will monitor wound progress and treatment plan weekly and make changes to treatments as appropriate if no wound healing progress >2 weeks.
