Oth incomplete lesion at C4, init

This code signifies an incomplete spinal cord injury at the C4 vertebral level, where some motor or sensory function is preserved below the neurological level of injury. It indicates that the injury is not a complete transection of the cord, and some neural pathways remain intact.

Apply this code for a patient presenting with a newly diagnosed or acutely managed incomplete C4 spinal cord lesion. Documentation should clearly specify the C4 level, the incomplete nature of the injury (e.g., ASIA Impairment Scale B, C, or D), and that this is the initial encounter for treatment.

• Ensure documentation specifies "incomplete" and the C4 level; do not use for complete lesions or unspecified levels.
• The "A" seventh character indicates an active treatment phase; subsequent encounters will use "D" or "S."
• Distinguish from S14.14XA (other specified incomplete lesion) if the specific type of incomplete lesion is not documented.
