About L90
L90 is the ICD-10-CM diagnosis code for atrophic disorders of skin. It belongs to block L80-L99 (other disorders of the skin and subcutaneous tissue) and chapter 12 (diseases of the skin and subcutaneous tissue). It is a header code, so it can't be reported by itself; one of its 9 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: L90.0 (atrophicus), L90.1 (Schweninger-Buzzi), L90.2 (Jadassohn-Pellizzari), L90.3 (Pierini), L90.4 (atrophicans), L90.5 (skin), L90.6 (atrophicae), L90.8 (skin) and 1 more.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
