HCPCS Code A6197: Alginate Dressing Under 48 Square Inches

A primary dressing is the material placed directly on the wound bed (e.g., alginate wound cover for exudative ulcers). It manages moisture and protects skin, often requiring a secondary dressing to secure.

A secondary dressing secures the primary layer, controls strike-through, and adds cushioning (bandage, adhesive film, or foam). Its role is to protect and maintain an optimal environment between dressing changes.

Coverage depends on the local coverage determination and whether the product category fits a payable HCPCS (often a foam or antibacterial foam code by size). Verify the LCD/Policy Article and document medical necessity with complete information.
