E34.5 vs Q56
E34.5 (Androgen insensitivity syndrome) compared with Q56 (Indeterminate sex and pseudohermaphroditism), 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. Q56 carries an Excludes1 note covering E34.5: “androgen insensitivity syndrome (E34.5-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
