Unsp intracranial injury w LOC of 1-5 hrs 59 min, init

This code signifies a head injury where the specific type of intracranial damage is not documented, but the patient experienced a loss of consciousness (LOC) lasting between 1 hour and 5 hours 59 minutes. It indicates the initial phase of treatment for this injury.

Apply this code for patients presenting with an intracranial injury of unknown specificity and a documented LOC within the specified time frame. Documentation should clearly state the duration of unconsciousness and that this is the first time the patient is being treated for this particular injury.

• Ensure the medical record explicitly states "unspecified intracranial injury" or lacks detail to code a more specific injury.
• Verify the duration of loss of consciousness falls precisely within the 1 hour to 5 hours 59 minutes range; different durations require different codes.
• The "A" seventh character indicates an initial encounter, meaning the patient is receiving active treatment for the injury.
