L72 vs Q84

L72 (Follicular cysts of skin and subcutaneous tissue) compared with Q84 (Other congenital malformations of integument), 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. L72 carries an Excludes1 note covering Q84: “congenital malformations of integument (Q84.-)”

Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
