S06.819D — Injury of right internal carotid artery, intracranial portion, not elsewhere classified with loss of consciousness of unspecified duration, subsequent encounter
Is S06.819D billable?
Yes, but S06.819D is an unspecified code. S06.819D is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, S06.819D 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 S06.819D — the more specific alternatives are listed below.

Excludes1 — never code together — inherited from S06
The conditions below can never be reported together with S06.819D 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 S06.819D to fully describe the condition. S06.819D 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 S06.819D, but a patient may have both at the same time. When documentation supports it, S06.819D and the excluded code may both be reported.

- effects of foreign body in ear (T16)
- effects of foreign body in larynx (T17.3)

- insect bite or sting, venomous (T63.4)
Code also — inherited from S00-S09
Two codes may be needed to describe the condition fully. Whether S06.819D is sequenced first depends on the reason for the encounter.

How long has S06.819D existed?
S06.819D 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.
