L14 vs Q82.8
L14 (Bullous disorders in diseases classified elsewhere) 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. L14 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).
