Is S06.8 a billable ICD-10-CM code?

No. S06.8 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does S06.8 sit in the tabular list?

Injury, poisoning and certain other consequences of external causes (S00-T88), in the block Injuries to the head (S00-S09).

What cannot be coded together with S06.8?

S06.8 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above S06.8 (S06) and apply to it just the same.

S06.8

S06.8 — Other specified intracranial injuries

Non-billable headerICD-10-CM

S06.8 is a non-billable header ICD-10-CM code for other specified intracranial injuries. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.

This code requires a 7th character

The appropriate 7th character is to be added to each code from category S06, except as noted below

A: initial encounter
D: subsequent encounter
S: sequela

Excludes1 inherited from the categories above S06.8

These are not written on S06.8, but they bind it: a note on a category applies to every code beneath it. Billing S06.8 with anything listed here is a denial.

Written on S06 — Intracranial injury

head injury NOS (S09.90)

Other codes that can never be billed with S06.8

These codes carry an Excludes1 note pointing at S06.8. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S06.8 alone.

G31.84Mild cognitive impairment of uncertain or unknown etiology
I69Sequelae of cerebrovascular disease
I69.8Sequelae of other cerebrovascular diseases
I69.9Sequelae of unspecified cerebrovascular diseases
S06.0Concussion
S06.9Unspecified intracranial injury
S09.0Injury of blood vessels of head, not elsewhere classified
S09.0XXAInjury of blood vessels of head, not elsewhere classified, initial encounter

Risk adjustment

S06.8 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code history

S06.8 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Code to one of these instead S06.8

4 child codes. Green means billable.
