PCSS's suggested HCPCS categories (July 2026) are for reference only, based on product type and pad size. It's a reference, not a coding determination. Confirm final coding with your billing staff.
Sizes are shown as PCSS lists them. For a bordered dressing, check the pad's dimensions before choosing a band.
General product information, not clinical advice.
Size band
CMS splits this dressing type into 3 bands: pad 16 sq. in. or less, pad more than 16 up to 48 sq. in. and pad more than 48 sq. in. Multiply the pad's length by its width: a 6×6 in. pad is 36 sq. in., which falls in A6213's band (more than 16 up to 48 sq. in.). For this bordered code, measure the pad only: the adhesive border isn't counted.
Listed for the PCSS product group, in PCSS's plain-words summary of the LCD.

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.
