S01.20XS vs S02
S01.20XS (Unspecified open wound 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. S01.20XS 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).
