E25.0 vs Q89.1
E25.0 (Congenital adrenogenital disorders associated with enzyme deficiency) compared with Q89.1 (Congenital malformations of adrenal gland), 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. Q89.1 carries an Excludes1 note covering E25.0: “adrenogenital disorders (E25.-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
No — do not report together. Q89.1 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).
