E23 vs E34.3
E23 (Hypofunction and other disorders of the pituitary gland) compared with E34.3 (Short stature due to endocrine disorder), 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. E23 carries an Excludes1 note covering E34.3: “short stature due to endocrine disorder (E34.3-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
