Primary blast injury of brain, NEC LOC of 31-59 min, sequela

This code signifies a brain injury sustained from a primary blast event, not classified elsewhere, where the patient experienced a loss of consciousness lasting between 31 and 59 minutes. The "S" at the end indicates that this is a sequela code, meaning it describes a late effect or complication of the initial injury.

Use this code when documenting the long-term effects or complications arising from a primary blast-induced brain injury that initially presented with a moderate period of unconsciousness. This applies to follow-up encounters for conditions directly attributable to the original blast injury. Documentation should clearly state the primary blast mechanism, the initial duration of unconsciousness, and the current sequela being treated.

• Ensure documentation explicitly links the current condition to the original primary blast injury.
• This code is for sequela; an acute injury would require a different code from the S06.8A category.
• Always sequence this code after the code(s) for the specific sequela being treated (e.g., cognitive deficits, post-concussive syndrome).
