Unsp focal TBI w LOC of 30 minutes or less, sequela

This code signifies the long-term effects or complications arising from a focal traumatic brain injury (TBI) where the patient experienced a loss of consciousness lasting 30 minutes or less. It indicates that the specific nature of the focal injury is not documented. This diagnosis is used when the acute injury has resolved, but residual symptoms or conditions persist.

Apply this code when a patient presents with sequelae (e.g., cognitive deficits, headaches, mood changes) directly attributable to a past, unspecified focal TBI with brief loss of consciousness. Documentation must clearly link the current symptoms to the previous TBI and specify that the loss of consciousness was 30 minutes or less. This code is appropriate for follow-up visits addressing chronic TBI-related issues.

• Always use an external cause code (e.g., W00-Y38) in conjunction with TBI codes to describe the cause of the injury, if known.
• Do not use this code for acute TBI; it is specifically for sequelae.
• Ensure documentation specifies "focal" injury and the duration of loss of consciousness to differentiate from diffuse TBI or TBI without loss of consciousness.
