Anterior cord syndrome at C3, sequela

This code signifies the long-term effects or residual conditions resulting from anterior cord syndrome affecting the C3 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. The "sequela" designation indicates that this code is used for chronic or late effects of the initial injury.

Use this code when documenting the permanent neurological deficits or chronic symptoms directly attributable to a past anterior cord syndrome at the C3 level. This applies to patients presenting for follow-up care, rehabilitation, or management of ongoing impairments such as spasticity, weakness, or sensory deficits. Documentation should clearly state the history of anterior cord syndrome at C3 and the current residual condition.

• Ensure documentation specifies "sequela" or "late effects" to justify the 7th character 'S'.
• Do not use this code for the initial acute injury; use an acute injury code for the initial encounter.
• Code any associated neurological deficits (e.g., spasticity, paralysis) separately as secondary diagnoses.
