S00.86XD vs S06.2
S00.86XD (Insect bite (nonvenomous) of other part of head, subsequent encounter) compared with S06.2 (Diffuse traumatic brain injury), 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. S00.86XD carries an Excludes1 note covering S06.2: “diffuse cerebral contusion (S06.2-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
