Unsp intracranial injury w LOC of 31-59 min, sequela

This code signifies a past, unspecified head injury that involved a loss of consciousness lasting between 31 and 59 minutes, and is now presenting with a residual effect or complication. The original injury's specific nature (e.g., concussion, contusion) was not documented or is unknown. The "sequela" indicates that the patient is currently experiencing a long-term consequence of this prior head trauma.

Use this code when a patient presents with a current condition that is a direct result of a previous intracranial injury where the loss of consciousness was documented as 31 to 59 minutes, but the specific type of intracranial injury was not specified. Documentation must clearly link the current symptoms or condition to the historical head trauma and specify the duration of unconsciousness. This code is appropriate for follow-up visits addressing chronic issues stemming from the original injury.

• Always sequence the sequela code first, followed by codes for the specific residual conditions being treated.
• Ensure documentation explicitly states "sequela" or clearly indicates a chronic condition resulting from a past injury.
• Verify the duration of loss of consciousness; codes vary significantly based on this timeframe.
