Excludes1 — never code together — inherited from S06
The conditions below can never be reported together with S06.310A 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 S06.310A to fully describe the condition. S06.310A is sequenced first.
- code to identify any retained foreign body, if applicable (Z18.-)
Use additional code — inherited from S06
Report an additional code alongside S06.310A to fully describe the condition. S06.310A is sequenced first.
- code, if applicable, to identify mild neurocognitive disorders due to known physiological condition (F06.7-)
Use additional code — inherited from S06.3
Report an additional code alongside S06.310A to fully describe the condition. S06.310A is sequenced first.
- code, if applicable, for traumatic brain compression or herniation (S06.A-)
Excludes2 — not included here — inherited from Chapter 19

Excludes2 — not included here — inherited from S06.3
The conditions below are not part of S06.310A, but a patient may have both at the same time. When documentation supports it, S06.310A and the excluded code may both be reported.
Code also — inherited from S00-S09
Two codes may be needed to describe the condition fully. Whether S06.310A is sequenced first depends on the reason for the encounter.

Two codes may be needed to describe the condition fully. Whether S06.310A is sequenced first depends on the reason for the encounter.
How long has S06.310A existed?
S06.310A has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
