LCD L33831(opens in a new tab)We list silver (Ag) and honey products by their base dressing type. Medicare's surgical dressing LCD lists silver and honey among materials whose safety and effectiveness “have not been established,” and classifies dressings by their clinically predominant component — one made predominantly of such materials isn't considered reasonable and necessary. Code each product by its PDAC listing; choose products on clinical judgment.
