L11 vs Q82.8
L11 (Other acantholytic disorders) compared with Q82.8 (Other specified congenital malformations of skin), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. L11 carries an Excludes1 note covering Q82.8: “benign familial pemphigus [Hailey-Hailey] (Q82.8)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
