Q03 vs Q75
Q03 (Congenital hydrocephalus) compared with Q75 (Other congenital malformations of skull and face bones), 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. Q75 carries an Excludes1 note covering Q03: “hydrocephalus (Q03.-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
