What This Code Means

L85.8 is the ICD-10-CM diagnosis code for other specified epidermal thickening. Thickening of the outer layer of skin that does not fit into other specific categories of epidermal thickening disorders. L85.8 sits in the ICD-10-CM chapter for diseases of the skin and subcutaneous tissue (l00-l99), within the section covering other disorders of the skin and subcutaneous tissue (l80-l99).

L85.8 is a billable ICD-10-CM code, but the current payload does not show a mapping under the CMS-HCC V28, V24, ESRD, or RxHCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.

Use this code only when the specific type of epidermal thickening cannot be classified elsewhere.

HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for L85.8 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
