Incomplete lesion of L4 level of lumbar spinal cord, sequela

This code signifies a partial injury to the spinal cord at the L4 vertebral level within the lumbar region, resulting in some preservation of motor or sensory function below the injury site. The "sequela" indicator specifies that this code is used for complications or conditions arising directly from a previous, acute L4 spinal cord injury, not the initial injury itself.

This code is appropriate for documenting long-term neurological deficits, chronic pain, motor weakness, or sensory disturbances that are directly attributable to an incompletely resolved L4 spinal cord lesion. It should be used when the patient is presenting for follow-up care or management of these persistent effects, rather than the initial acute trauma.

• Always ensure documentation clearly specifies the L4 level and the incomplete nature of the lesion.
• The "S" seventh character indicates sequela; ensure this is appropriate for the patient's current encounter and not an acute injury.
• Code any associated neurological deficits (e.g., paralysis, sensory loss) separately to provide a complete clinical picture.
