E86 (Volume depletion) compared with T79.4 (Traumatic shock), 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. E86 carries an Excludes1 note covering T79.4: “traumatic hypovolemic shock (T79.4)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
