Unsp focal TBI w LOC of 1-5 hrs 59 min, sequela

This code signifies a long-term consequence or late effect stemming from an unspecified localized brain injury that initially caused a loss of consciousness lasting between one and just under six hours. It indicates that the acute phase of the injury has passed, and the patient is now experiencing residual symptoms or conditions directly attributable to that past trauma.

Apply this code when documentation clearly indicates a sequela (e.g., chronic headache, cognitive deficits, post-concussive syndrome) resulting from a focal traumatic brain injury where the initial loss of consciousness was recorded as 1 to 5 hours and 59 minutes. This code is appropriate for encounters addressing the chronic effects, not the initial injury.

• Always sequence this sequela code first when the sequela is the reason for the encounter.
• Requires documentation of the specific sequela (e.g., G44.3 for post-traumatic headache) to be coded secondarily.
• Ensure the duration of loss of consciousness is explicitly documented to fall within the 1-hour to 5-hour 59-minute range; otherwise, a different S06.30- code may be more appropriate.
