S01.25XS vs S02
S01.25XS (Open bite of nose, sequela) compared with S02 (Fracture of skull and facial bones), 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. S01.25XS carries an Excludes1 note covering S02: “open skull fracture (S02.- with 7th character B)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
