Unspecified focal TBI with LOC status unknown, sequela

This code signifies a long-term consequence or complication stemming from a focal traumatic brain injury where the specific type of focal injury is not documented. The patient's loss of consciousness status at the time of the initial injury is unknown. This code is used when the acute injury has resolved, but residual effects persist.

This code is appropriate for documenting chronic neurological deficits, cognitive impairments, or behavioral changes directly attributable to a past focal TBI. Documentation should clearly state that the condition is a sequela of a TBI, specify the focal nature of the original injury (even if unspecified further), and indicate that the loss of consciousness status is unknown.

• Always sequence this sequela code after the code for the specific residual condition being treated (e.g., hemiplegia, cognitive deficit).
• Do not use this code for acute TBI; it is exclusively for chronic, residual effects.
• Ensure documentation explicitly links the current condition to a past focal TBI and notes the unknown LOC status.
