Primary blast injury of brain, NEC without LOC, sequela

This code describes the long-term effects or complications arising from a primary blast injury to the brain, where the patient did not experience a loss of consciousness at the time of the initial injury. It signifies a residual condition directly attributable to the blast force impacting the brain, distinct from other brain injuries.

Use this code when documenting a patient presenting with ongoing neurological or cognitive deficits, or other sequelae, that are directly linked to a primary blast injury of the brain where loss of consciousness was explicitly absent. Documentation should clearly state the blast as the cause and the absence of initial loss of consciousness.

• Ensure documentation specifies "primary blast injury" and explicitly states "without loss of consciousness" to support this specific code.
• This code is for sequela; an additional code for the specific neurological or cognitive deficit (e.g., cognitive impairment, headache) should be reported first.
• Do not use this code for acute blast injuries; it is strictly for the long-term effects.
