G93.5 vs S06.A
G93.5 (Compression of brain) compared with S06.A (Traumatic brain compression and herniation), 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. G93.5 carries an Excludes1 note covering S06.A: “traumatic compression of brain (S06.A-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
