- head injury NOS (S09.90)
Excludes1 — never code together — inherited from S06.0
The conditions below can never be reported together with S06.0X1D on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

- frostbite (T33-T34)
- insect bite or sting, venomous (T63.4)
Code also — inherited from S00-S09
Two codes may be needed to describe the condition fully. Whether S06.0X1D is sequenced first depends on the reason for the encounter.
- for any associated infection
Code also — inherited from S06
Two codes may be needed to describe the condition fully. Whether S06.0X1D is sequenced first depends on the reason for the encounter.
How long has S06.0X1D existed?
S06.0X1D has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
