About S06.0

S06.0 is the ICD-10-CM diagnosis code for concussion. It belongs to category S06 (intracranial injury), block S00-S09 (injuries to the head) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 1 subcodes must be used instead.

Within S06 (intracranial injury), S06.0 is specifically for concussion. Related codes cover 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), unspecified intracranial injury (S06.9) 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 S06.0 together with the conditions in its Excludes1 note: concussion with other intracranial injuries classified in subcategories S06.1- to S06.6-, and S06.81- to S06.89-, code to specified intracranial injury.

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