Unsp injury at C1 level of cervical spinal cord, sequela

This code signifies a long-term complication or residual effect stemming from an unspecified injury to the C1 level of the cervical spinal cord. It indicates that the initial acute injury has resolved, but the patient continues to experience lasting neurological deficits or other sequelae directly attributable to that past trauma.

Apply this code when documentation clearly indicates a current condition or symptom is a direct consequence of a previous, unspecified C1 spinal cord injury. This is appropriate for follow-up encounters where the focus is on managing chronic issues, such as persistent weakness, spasticity, or sensory loss, resulting from the old injury.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., spasticity, paralysis).
• Ensure the "S" seventh character is used only for sequela, indicating a late effect.
• Verify documentation explicitly links the current condition to a past C1 spinal cord injury, and that the nature of the initial injury was not specified.
