E30.1 vs N93
E30.1 (Precocious puberty) compared with N93 (Other abnormal uterine and vaginal bleeding), 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. N93 carries an Excludes1 note covering E30.1: “precocious puberty (menstruation) (E30.1)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
