S00.32XA vs S01
S00.32XA (Blister (nonthermal) of nose, initial encounter) compared with S01 (Open wound of head), 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. S00.32XA carries an Excludes1 note covering S01: “open wound of head (S01.-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
