About coding brain traumatic injury

The ICD-10-CM code for brain traumatic injury is S06.9 (Unspecified intracranial injury). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on S06.9.

Within S06, choose S06.9 (Unspecified intracranial injury) only when documentation doesn't support a more specific option: concussion (S06.0), traumatic cerebral edema (S06.1), diffuse traumatic brain injury (S06.2), focal traumatic brain injury (S06.3), epidural hemorrhage (S06.4), traumatic subdural hemorrhage (S06.5), traumatic subarachnoid hemorrhage (S06.6), other specified intracranial injuries (S06.8) and 1 more.

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

Don't report S06.9 together with the conditions in its Excludes1 note: conditions classifiable to S06.0- to S06.8-code to specified intracranial injury and head injury NOS (S09.90).

More specific brain traumatic injury codes (official index)

  • diffuse (axonal) S06.2X — Diffuse traumatic brain injury
  • focal S06.30 — Unspecified focal traumatic brain injury

Don't confuse with (Excludes1 for S06.9)

  • conditions classifiable to S06.0- to S06.8-code to specified intracranial injury
  • head injury NOS (S09.90)
