Anterior cord syndrome at C8, subs

This code describes a specific neurological deficit, anterior cord syndrome, affecting the C8 level of the cervical spinal cord. This syndrome typically results in motor paralysis, loss of pain and temperature sensation below the lesion, while preserving proprioception, vibration, and touch. The "D" suffix indicates this is a subsequent encounter for care after the initial treatment phase.

Use this code for follow-up visits, rehabilitation sessions, or ongoing management of a patient previously diagnosed and treated for anterior cord syndrome at the C8 level. Documentation should clearly state the C8 level involvement and confirm the patient is in the healing or recovery phase, not the initial acute injury phase.

• Ensure documentation specifies "anterior cord syndrome" and the C8 level; general spinal cord injury codes are insufficient.
• Verify the encounter type is subsequent (D) and not initial (A) or sequela (S).
• Always code the underlying cause of the anterior cord syndrome (e.g., fracture, disc herniation) first, if applicable and still being treated.
