Anterior cord syndrome at C1, sequela

This code signifies the long-term effects or complications arising from anterior cord syndrome affecting the C1 level of the cervical spinal cord. Anterior cord syndrome is characterized by motor paralysis, loss of pain and temperature sensation below the lesion, while proprioception, vibration, and touch sensation are preserved. "Sequela" indicates that this code is used for conditions that are residual or chronic consequences of the initial injury, not the acute injury itself.

Use this code when documenting the chronic neurological deficits or persistent symptoms directly attributable to a past anterior cord syndrome injury at the C1 level. Documentation should clearly state the C1 level involvement and indicate that the condition is a sequela, such as "chronic motor weakness due to remote C1 anterior cord syndrome" or "persistent sensory loss secondary to old C1 anterior cord injury."

• Always ensure documentation specifies the C1 level and explicitly states "sequela" or a similar term indicating a chronic condition.
• Do not use this code for the initial or acute phase of anterior cord syndrome; separate codes exist for acute injuries.
• Consider sequencing this code after any primary diagnosis that further elaborates on the specific chronic neurological deficit (e.g., spasticity, paralysis).
