S06.334Contusion and laceration of cerebrum, unspecified, with loss of consciousness of 6 hours to 24 hours

S06.334 is the ICD-10-CM diagnosis code for contusion and laceration of cerebrum, unspecified, with loss of consciousness of 6 hours to 24 hours. 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 3 subcodes must be used instead.

Within S06.33 (contusion and laceration of cerebrum, unspecified), S06.334 is specifically for contusion and laceration of cerebrum, unspecified, with loss of consciousness of 6 hours to 24 hours. Related codes cover without loss of consciousness (S06.330), with loss of consciousness of 30 minutes or less (S06.331), with loss of consciousness of 31 minutes to 59 minutes (S06.332), with loss of consciousness of 1 hour to 5 hours 59 minutes (S06.333), with loss of consciousness greater than 24 hours with return to pre-existing conscious level (S06.335), with loss of consciousness greater than 24 hours without return to pre-existing conscious level with patient surviving (S06.336), with loss of consciousness of any duration with death due to brain injury prior to regaining consciousness (S06.337), with loss of consciousness of any duration with death due to other cause prior to regaining consciousness (S06.338) and 2 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.

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

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
