L90 — Atrophic disorders of skin
Non-billable headerICD-10-CM
L90 is a non-billable header ICD-10-CM code for atrophic disorders of skin. It cannot be billed on its own: choose one of the more specific child codes below.

L90 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.
