O71 vs S37.81
O71 (Other obstetric trauma) compared with S37.81 (Injury 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. S37.81 carries an Excludes1 note covering O71: “obstetric trauma to pelvic organs (O71.-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
