About coding intracranial injury
The ICD-10-CM code for intracranial injury is S06.9 (Unspecified intracranial injury). The official index lists 12 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).
