S06.2XADiffuse traumatic brain injury with loss of consciousness status unknown

S06.2XA is the ICD-10-CM diagnosis code for diffuse traumatic brain injury with loss of consciousness status unknown. 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 S06.2X (diffuse traumatic brain injury), S06.2XA is specifically for diffuse traumatic brain injury with loss of consciousness status unknown. Related codes cover without loss of consciousness (S06.2X0), with loss of consciousness of 30 minutes or less (S06.2X1), with loss of consciousness of 31 minutes to 59 minutes (S06.2X2), with loss of consciousness of 1 hour to 5 hours 59 minutes (S06.2X3), with loss of consciousness of 6 hours to 24 hours (S06.2X4), with loss of consciousness greater than 24 hours with return to pre-existing conscious levels (S06.2X5), with loss of consciousness greater than 24 hours without return to pre-existing conscious level with patient surviving (S06.2X6), with loss of consciousness of any duration with death due to brain injury prior to regaining consciousness (S06.2X7) 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-).
