L85Other epidermal thickening

Non-billable headerICD-10-CM

L85 is a non-billable header ICD-10-CM code for other epidermal thickening. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes2 — not included here, but may coexist

  • hypertrophic disorders of the skin (L91.-)

  • R23.4Changes in skin texture

Risk adjustment

L85 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead L85

6 child codes. Green means billable.
