Excludes1 — never code together — inherited from S06
The conditions below can never be reported together with S06.A0XD on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- head injury NOS (S09.90)
Code first — inherited from S06.A
The underlying condition below must be sequenced before S06.A0XD. S06.A0XD describes a manifestation and cannot be the principal or first-listed diagnosis.
Use additional code — inherited from Chapter 19
Report an additional code alongside S06.A0XD to fully describe the condition. S06.A0XD is sequenced first.
- code to identify any retained foreign body, if applicable (Z18.-)

- 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.A0XD is sequenced first depends on the reason for the encounter.
- for any associated infection
