Is anyone familiar with this product? It was used on a nonhealing wound as a skin replacement/substitute. The procedure says: "Preparation of wound bed and placement of Unite Biomatrix". The documentation for the product says it is a "biopcompatible, highly organized, non-reconstituted collagen mastrix derived from equine pericardium. The collagen dressing is decellularized...." I'm not sure if it would be coded as an acellular dermal replacement (15170) or a Xenograft (15400), or something else. Does anyone have any information or any thoughts on this. I really am stumped. Thanks in advance.
