S06.82 — Injury of left internal carotid artery, intracranial portion, not elsewhere classified

Not billable

Is S06.82 billable?

No — S06.82 is a non-billable header code. S06.82 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 S06.82.

Excludes1 — never code together — inherited from S06

The conditions below can never be reported together with S06.82 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 S06.82 to fully describe the condition. S06.82 is sequenced first.

code to identify any retained foreign body, if applicable (Z18.-)

Use additional code — inherited from S06

Report an additional code alongside S06.82 to fully describe the condition. S06.82 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 S06.82, but a patient may have both at the same time. When documentation supports it, S06.82 and the excluded code may both be reported.

birth trauma (P10-P15)
obstetric trauma (O70-O71)

Excludes2 — not included here — inherited from S00-S09

The conditions below are not part of S06.82, but a patient may have both at the same time. When documentation supports it, S06.82 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 S06.82 is sequenced first depends on the reason for the encounter.
