F07.81 vs S06.0X
F07.81 (Postconcussional syndrome) compared with S06.0X (Concussion), 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. F07.81 carries an Excludes1 note covering S06.0X: “current concussion (brain) (S06.0X- with seventh character A)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
