Is S06 a billable ICD-10-CM code?

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

Where does S06 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?

S06 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter.

S06

S06 — Intracranial injury

Non-billable headerICD-10-CM

S06 is a non-billable header ICD-10-CM code for intracranial injury. 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 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

head injury NOS (S09.90)

Use additional code

Add a secondary code to capture the detail described below.

code, if applicable, to identify mild neurocognitive disorders due to known physiological condition (F06.7-)

Code also

Both codes may be needed to describe the encounter fully. Sequencing depends on the reason for the visit.

any associated:
open wound of head (S01.-)
skull fracture (S02.-)

Conditions this code covers.

traumatic brain injury

Notes

Additional guidance from the ICD-10-CM tabular list.

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.

Other codes that can never be billed with S06

These codes carry an Excludes1 note pointing at S06. 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 alone.

F07.81Postconcussional syndrome
G31.84Mild cognitive impairment of uncertain or unknown etiology
G93.5Compression of brain
G93.6Cerebral edema
I69Sequelae of cerebrovascular disease
I69.8Sequelae of other cerebrovascular diseases
I69.9Sequelae of unspecified cerebrovascular diseases
S00Superficial injury of head

Risk adjustment

S06 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 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

10 child codes. Green means billable.
