S25.0 vs S35.0
S25.0 (Injury of thoracic aorta) compared with S35.0 (Injury of abdominal aorta), 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. S35.0 carries an Excludes1 note covering S25.0: “injury of aorta NOS (S25.0)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
