S06 — Intracranial injury
Not billable
Is S06 billable?
No — S06 is a non-billable header code. S06 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 60 billable codes beneath S06.

Excludes1 — never code together
The conditions below can never be reported together with S06 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
Report an additional code alongside S06 to fully describe the condition. S06 is sequenced first.
- code, if applicable, to identify mild neurocognitive disorders due to known physiological condition (F06.7-)
Code also
Two codes may be needed to describe the condition fully. Whether S06 is sequenced first depends on the reason for the encounter.
Includes
Conditions classified to S06.
- traumatic brain injury
Note
- 7th characters D and S do not apply to codes in category S06 with 6th character 7 - death due to brain injury prior to regaining consciousness, or 8 - death due to other cause prior to regaining consciousness.
Use additional code — inherited from Chapter 19
Report an additional code alongside S06 to fully describe the condition. S06 is sequenced first.
- code to identify any retained foreign body, if applicable (Z18.-)
Excludes2 — not included here — inherited from Chapter 19
The conditions below are not part of S06, but a patient may have both at the same time. When documentation supports it, S06 and the excluded code may both be reported.
Excludes2 — not included here — inherited from S00-S09
The conditions below are not part of S06, but a patient may have both at the same time. When documentation supports it, S06 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 is sequenced first depends on the reason for the encounter.
- for any associated infection

How long has S06 existed?
S06 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?
ICD-10-CM declares these codes mutually exclusive with S06 — exactly one of each pair can be correct for a given encounter.
