Unsp focal TBI w LOC of unsp duration, sequela

This code signifies a long-term effect or complication arising from a focal traumatic brain injury (TBI) where the initial injury involved an unspecified duration of loss of consciousness. It indicates that the specific type of focal TBI (e.g., contusion, laceration) is not documented, and the sequelae are the current focus of treatment.

Use this code when documenting the residual effects or chronic conditions resulting from a past focal TBI with unstated loss of consciousness. This is appropriate when the acute phase of the injury has passed, and the patient is being treated for persistent neurological deficits, cognitive impairments, or other lasting consequences directly attributable to the original trauma. Documentation should clearly link the current condition to a previous focal TBI.

• Requires a seventh character "S" to indicate sequela, meaning the patient is being treated for the residual effects of the injury.
• Do not use for acute TBI; instead, select an appropriate acute TBI code from the S06 category.
• Always sequence this code after the codes for the specific sequelae being treated (e.g., cognitive deficits, epilepsy, hemiplegia).
