- Injury › blastNEC › brain › primary, specified NEC
Excludes1 — never code together — inherited from S06
The conditions below can never be reported together with S06.8A4 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)
Use additional code — inherited from Chapter 19
Report an additional code alongside S06.8A4 to fully describe the condition. S06.8A4 is sequenced first.
- code to identify any retained foreign body, if applicable (Z18.-)
Use additional code — inherited from S06
Report an additional code alongside S06.8A4 to fully describe the condition. S06.8A4 is sequenced first.
- code, if applicable, to identify mild neurocognitive disorders due to known physiological condition (F06.7-)
Excludes2 — not included here — inherited from Chapter 19
The conditions below are not part of S06.8A4, but a patient may have both at the same time. When documentation supports it, S06.8A4 and the excluded code may both be reported.
Excludes2 — not included here — inherited from S00-S09
The conditions below are not part of S06.8A4, but a patient may have both at the same time. When documentation supports it, S06.8A4 and the excluded code may both be reported.
- burns and corrosions (T20-T32)
- effects of foreign body in ear (T16)
- effects of foreign body in larynx (T17.3)

Two codes may be needed to describe the condition fully. Whether S06.8A4 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 S06.8A4 is sequenced first depends on the reason for the encounter.
