About S06.8A

S06.8A is the ICD-10-CM diagnosis code for primary blast injury of brain, not elsewhere classified. 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 11 subcodes must be used instead.

Within S06.8 (other specified intracranial injuries), S06.8A is specifically for primary blast injury of brain, not elsewhere classified. Related codes cover injury of right internal carotid artery, intracranial portion, not elsewhere classified (S06.81), injury of left internal carotid artery, intracranial portion, not elsewhere classified (S06.82) and other specified intracranial injury (S06.89).

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.

The conditions in its Excludes2 note aren't part of S06.8A, but may be coded alongside it if the patient has both: traumatic cerebral edema (S06.1).

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

It was added in FY2023, effective October 1, 2022.
