When reporting dressings for wounds, it is important to indicate if the dressing is the primary or secondary dressing as well the number of wounds the dressing will be used for.
Primary Dressing: May be therapeutic or protective coverings applied to wounds either on the skin or caused by an opening to the skin or lesions may be applied to lesions.
Secondary Dressing: Examples may be tape elastic bandages or a roll of gauze used to secure the primary dressing.
Modifiers A1-A9 indicate the number of wounds the dressing was applied to. These are informational only, but very important for proper reimbursement for wound care.
