S06.8AAS — Primary blast injury of brain, not elsewhere classified with loss of consciousness status unknown, sequela
Is S06.8AAS billable?
Yes, but S06.8AAS is an unspecified code. S06.8AAS is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, S06.8AAS is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting S06.8AAS — the more specific alternatives are listed below.

Inclusion terms
Alternative wording in documentation that is classified to S06.8AAS.
- Primary blast injury of brain NOS
Excludes1 — never code together — inherited from S06
The conditions below can never be reported together with S06.8AAS 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 S06.8AAS to fully describe the condition. S06.8AAS is sequenced first.
- code to identify any retained foreign body, if applicable (Z18.-)
Use additional code — inherited from S06
Report an additional code alongside S06.8AAS to fully describe the condition. S06.8AAS 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 S06.8AAS, but a patient may have both at the same time. When documentation supports it, S06.8AAS and the excluded code may both be reported.

Excludes2 — not included here — inherited from S06.8A
The conditions below are not part of S06.8AAS, but a patient may have both at the same time. When documentation supports it, S06.8AAS and the excluded code may both be reported.
- traumatic cerebral edema (S06.1)
Code also — inherited from S00-S09
Two codes may be needed to describe the condition fully. Whether S06.8AAS 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 S06.8AAS is sequenced first depends on the reason for the encounter.

How long has S06.8AAS existed?
S06.8AAS first appears in FY2023.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
