Brown-Sequard syndrome at C2, subs

This code signifies a partial spinal cord lesion at the C2 cervical level, characterized by ipsilateral motor paralysis and loss of proprioception, combined with contralateral loss of pain and temperature sensation. This specific diagnosis indicates the patient is receiving follow-up care for this condition after the initial active treatment phase.

Apply this code for patients presenting for ongoing treatment, rehabilitation, or monitoring of Brown-Sequard syndrome affecting the C2 spinal cord segment. Documentation should clearly indicate the C2 level involvement and specify that the encounter is not for the initial acute injury or active treatment.

• Ensure documentation explicitly states "subsequent encounter" or similar language indicating follow-up care.
• Verify the specific cervical level (C2) is documented; other levels have different codes.
• Distinguish from initial encounters (initial encounter codes) or sequelae (sequela codes) if the condition is long-standing and stable.
