ICD-10: S06.824

The ICD-10 code S06.824 refers to an injury of the left internal carotid artery, specifically in the intracranial portion, that is not classified elsewhere and is associated with a loss of consciousness lasting between 6 to 24 hours. This code is part of the broader category of codes that deal with traumatic brain injuries and vascular injuries.

Clinical Description

Definition

The internal carotid artery is a major blood vessel that supplies blood to the brain. An injury to this artery, particularly in its intracranial segment, can lead to significant neurological consequences due to compromised blood flow. The designation "not elsewhere classified" indicates that this specific injury does not fit into other predefined categories of injuries or conditions.

Loss of Consciousness

The inclusion of loss of consciousness (LOC) lasting from 6 to 24 hours is critical in the clinical assessment of the patient. LOC can be indicative of a more severe injury, such as a concussion or other traumatic brain injury (TBI), and may require immediate medical evaluation and intervention. The duration of LOC is a key factor in determining the severity of the injury and guiding treatment protocols.

Symptoms and Signs

Patients with an injury to the left internal carotid artery may present with various symptoms, including:
