About this chapter
ICD-10-CM Chapter XII — “Diseases of the skin and subcutaneous tissue” — spans every category from L00 through L99. Each category in that range expands into a header code and one or more billable codes with additional specificity (laterality, episode of care, or clinical detail). Open any code’s own page to see its exact position in the hierarchy, its parent and children, and whether it’s billable.
