Anterior cord syndrome at C5, init

This code signifies a specific neurological deficit resulting from damage to the anterior spinal artery or the anterior portion of the spinal cord at the C5 vertebral level. Patients typically present with immediate paralysis and loss of pain and temperature sensation below the lesion, while proprioception and vibratory sensation are preserved. This syndrome is often caused by trauma, disc herniation, or vascular compromise.

Use this code for the initial encounter of a patient diagnosed with anterior cord syndrome specifically affecting the C5 level of the cervical spinal cord. Documentation should clearly state the diagnosis of anterior cord syndrome, specify the C5 level, and indicate that this is the first time the patient is being treated for this condition. This code is appropriate for acute presentations following injury or sudden onset of symptoms.

• Ensure documentation explicitly states "anterior cord syndrome" and the C5 level; avoid using for incomplete or unspecified cord syndromes.
• Verify the "initial encounter" designation; subsequent encounters for the same condition will require a different seventh character.
• Code any associated trauma (e.g., fracture, dislocation) or underlying cause separately and sequence appropriately.
