E16.2 vs E74
E16.2 (Hypoglycemia, unspecified) compared with E74 (Other disorders of carbohydrate 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. E74 carries an Excludes1 note covering E16.2: “hypoglycemia NOS (E16.2)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
