Unsp focal TBI w loss of consciousness of 31-59 min, sequela

This code signifies a long-term consequence or late effect stemming from an unspecified focal traumatic brain injury where the patient experienced a loss of consciousness lasting between 31 and 59 minutes. "Focal" indicates the injury was localized to a specific area of the brain, rather than diffuse. "Sequela" denotes that this code is used to report conditions that are residual effects of the initial injury, occurring after the acute phase has passed.

Apply this code when documenting a patient presenting with a chronic condition or complication directly attributable to a focal TBI with a documented loss of consciousness of 31-59 minutes, after the initial injury has healed. Documentation must clearly link the current condition to the past TBI and specify the duration of unconsciousness. This code is appropriate for follow-up visits addressing the lasting impact of the injury.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic headache, cognitive deficit) being treated.
• Ensure the medical record explicitly states "sequela" or "late effect" and specifies the duration of loss of consciousness from the original injury.
• Distinguish from acute TBI codes (S06.30XA-D) which are used for the initial injury encounter.
