S06.9 — Unspecified intracranial injury
Is S06.9 billable?
No — S06.9 is a non-billable header code. S06.9 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 29 billable codes beneath S06.9.

How is S06.9 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to S06.9. They show the wording a clinician may have documented, which often differs from the Tabular description.
- TBI (traumatic brain injury)
- Injury › brain
- Injury › intracranial
- Traumatic › brain injury
- Injury › head › with loss of consciousness
Excludes1 — never code together
The conditions below can never be reported together with S06.9 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Inclusion terms
Alternative wording in documentation that is classified to S06.9.
- Brain injury NOS
- Head injury NOS with loss of consciousness
- Traumatic brain injury NOS
Excludes1 — never code together — inherited from S06
The conditions below can never be reported together with S06.9 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 S06.9 to fully describe the condition. S06.9 is sequenced first.
- code to identify any retained foreign body, if applicable (Z18.-)
Use additional code — inherited from S06
Report an additional code alongside S06.9 to fully describe the condition. S06.9 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 S06.9, but a patient may have both at the same time. When documentation supports it, S06.9 and the excluded code may both be reported.
Excludes2 — not included here — inherited from S00-S09
The conditions below are not part of S06.9, but a patient may have both at the same time. When documentation supports it, S06.9 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)
- effects of foreign body in mouth NOS (T18.0)
- effects of foreign body in nose (T17.0-T17.1)
- effects of foreign body in pharynx (T17.2)
- effects of foreign body on external eye (T15.-)
- 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 S06.9 is sequenced first depends on the reason for the encounter.
- for any associated infection

What codes fall under S06.9? (1)
How long has S06.9 existed?
S06.9 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
Which codes are confused with S06.9?
ICD-10-CM declares these codes mutually exclusive with S06.9 — exactly one of each pair can be correct for a given encounter.
