According to the Durable Medical Equipment Medicare Administrative Contractors (DMEMACs), the definitions of primary and secondary surgical dressings are:
Primary Dressing – Therapeutic or protective covering applied directly to wounds or lesions either on the skin or caused by an opening to the skin.
Secondary Dressing – Materials that serve a therapeutic or protective function and that are needed to secure a primary dressing.
Some surgical dressings can only serve as a primary dressing, while others can only serve as a secondary dressing. There are even some that can serve as either a primary or secondary dressing depending on how it is being used.
When dispensing a surgical dressing, the DMEMAC Surgical Dressings Policy Article (A54563) states that the documentation must include whether the dressing is being used as a primary dressing or secondary dressing. This should never be left subject to interpretation or assumption by an auditor, but instead clearly documented.
It is suggested that the note contain a sentence that states, “This product will be used as a ___________ (fill in primary or secondary) dressing.” If dispensing multiple products at the same time, as in the case of an AMERX® Wound Care Kit, each product should be accounted for and this designation of primary versus secondary use should be made for each product. This could require a sentence such as, “The collagen powder in this kit will be used as a primary dressing and the bordered gauze in this kit will be used as a secondary dressing.”
If you need assistance determining the primary/secondary designation of AMERX dressings, this summary may be helpful:
It is important that providers understand the difference between a primary dressing and a secondary dressing and clearly document whether the dressing(s) being dispensed are to be used as a primary or secondary dressing.
