About coding TBI

The ICD-10-CM code for TBI is S06.9 (Unspecified intracranial injury).

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).

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)
