S06.306S — Unspecified focal traumatic brain injury with loss of consciousness greater than 24 hours without return to pre-existing conscious level with patient surviving, sequela
Is S06.306S billable?
Yes, but S06.306S is an unspecified code. S06.306S is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, S06.306S 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 S06.306S — the more specific alternatives are listed below.

Excludes1 — never code together — inherited from S06
The conditions below can never be reported together with S06.306S 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 S06.306S to fully describe the condition. S06.306S is sequenced first.
- code to identify any retained foreign body, if applicable (Z18.-)
Use additional code — inherited from S06
Report an additional code alongside S06.306S to fully describe the condition. S06.306S 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 S06.306S to fully describe the condition. S06.306S is sequenced first.
- code, if applicable, for traumatic brain compression or herniation (S06.A-)
Excludes2 — not included here — inherited from Chapter 19
The conditions below are not part of S06.306S, but a patient may have both at the same time. When documentation supports it, S06.306S and the excluded code may both be reported.
Excludes2 — not included here — inherited from S00-S09
The conditions below are not part of S06.306S, but a patient may have both at the same time. When documentation supports it, S06.306S 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)

- insect bite or sting, venomous (T63.4)
Excludes2 — not included here — inherited from S06.3
The conditions below are not part of S06.306S, but a patient may have both at the same time. When documentation supports it, S06.306S 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 S06.306S is sequenced first depends on the reason for the encounter.

How long has S06.306S existed?
S06.306S 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.
