Concussion w LOC of 30 minutes or less, init

This code signifies a mild traumatic brain injury (MTBI) characterized by a temporary neurological dysfunction resulting from a direct or indirect force to the head. The key feature is a brief period of unconsciousness, lasting no more than 30 minutes, immediately following the injury.

Apply this code for patients presenting with a concussion where the medical record clearly documents a loss of consciousness (LOC) that resolved within 30 minutes. This is appropriate for the initial assessment and treatment of the injury. Documentation should specify the duration of LOC.

• Ensure the documentation explicitly states "loss of consciousness" and its duration to differentiate from concussions without LOC or with prolonged LOC.
• Do not use this code for subsequent encounters; a different seventh character (D, S) would be appended.
• Carefully review the medical record to confirm the LOC duration is indeed 30 minutes or less, as this is a critical distinguishing factor for this specific code.
