Intcran inj w LOC of 30 minutes or less, subs

This code signifies a type of head injury involving damage to the brain or its surrounding structures, not otherwise specified, that resulted in a brief period of unconsciousness lasting 30 minutes or less. This diagnosis is applied when the patient is receiving follow-up care for this specific intracranial injury.

Use this code for patients presenting for ongoing treatment, rehabilitation, or follow-up appointments related to a previously diagnosed other specified intracranial injury that initially caused a short loss of consciousness. Documentation should clearly indicate the nature of the intracranial injury, the duration of the initial loss of consciousness (30 minutes or less), and that this is a subsequent encounter for the condition.

• Ensure documentation specifies "subsequent encounter" to justify the 7th character 'D'.
• Differentiate from initial encounters (7th character 'A') or sequela (7th character 'S').
• Verify the duration of loss of consciousness; codes exist for longer periods or no loss of consciousness.
