E34.5 vs E80

E34.5 (Androgen insensitivity syndrome) compared with E80 (Disorders of porphyrin and bilirubin metabolism), 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. E80 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).
