Traum subrac hem w LOC of 30 minutes or less, sequela

This code signifies a long-term effect or complication arising from a traumatic subarachnoid hemorrhage where the patient experienced a brief loss of consciousness (30 minutes or less) at the time of the initial injury. It indicates that the patient is now presenting for care related to a residual condition or sequela directly attributable to that past traumatic event.

Apply this code when documentation clearly states the patient is being treated for a sequela (e.g., chronic headache, cognitive deficits, post-concussive syndrome) directly resulting from a previously sustained traumatic subarachnoid hemorrhage with an initial loss of consciousness of 30 minutes or less. The medical record must explicitly link the current condition to the past traumatic brain injury.

• Always sequence the sequela code (S06.6X1S) after the code for the specific residual condition being treated.
• Ensure documentation specifies "sequela" or "late effect" and clearly links the current symptoms to the past traumatic subarachnoid hemorrhage.
• Distinguish from acute traumatic subarachnoid hemorrhage codes (S06.6X1A, D) which are used for initial encounters or subsequent active treatment of the injury itself.
