About the L80–L99 Code Range
Skin color changes, thickened skin, scars, and ulcers appear alongside other disorders of the skin and tissue beneath it. In vitiligo, patches of skin lose pigmentation.
L80 identifies vitiligo. L81 separates other pigmentation changes, including freckles and conditions with increased or diminished pigment. L82 distinguishes inflamed from other seborrheic keratosis, while L85 separates types of skin-surface thickening. L90 includes scars among conditions involving skin thinning; L91 groups conditions involving skin thickening, including raised scars.
A pressure ulcer results from prolonged pressure on skin and underlying tissue. L89 separates these ulcers by body site. L97 separates chronic lower-limb ulcers not caused by pressure by site, while L98 includes other skin disorders and non-pressure chronic ulcers of the skin or upper limb.
