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

This code signifies a head injury where the specific type of intracranial damage is not documented, and the patient experienced a loss of consciousness lasting between 31 and 59 minutes. This diagnosis is used for encounters following the initial treatment of the injury.

Apply this code for follow-up visits, rehabilitation, or ongoing management of a patient who sustained an unspecified intracranial injury with a documented loss of consciousness within the specified timeframe. Documentation must clearly indicate the duration of unconsciousness and that this is not the initial encounter for the injury.

• Ensure the medical record explicitly states "subsequent encounter" or indicates ongoing care for the injury.
• Verify the duration of loss of consciousness is precisely between 31 and 59 minutes; other durations require different codes.
• Avoid using this code if a more specific intracranial injury (e.g., concussion, contusion) is documented.
