E25.0 vs E84

E25.0 (Congenital adrenogenital disorders associated with enzyme deficiency) compared with E84 (Cystic fibrosis), 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. E84 carries an Excludes1 note covering E25.0: “congenital adrenal hyperplasia (E25.0)”

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