Q04 vs Q87.0
Q04 (Other congenital malformations of brain) compared with Q87.0 (Congenital malformation syndromes predominantly affecting facial appearance), 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. Q04 carries an Excludes1 note covering Q87.0: “cyclopia (Q87.0)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
