Size band
Pad size sets the 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 A6204's band (more than 16 up to 48 sq. in.). For this bordered code, measure the pad only: the adhesive border isn't counted.
Usual change frequency (LCD L33831)
