Unsp injury at T1 level of thoracic spinal cord, sequela

This code signifies a long-term or late-effect complication resulting from an unspecified injury to the thoracic spinal cord at the T1 vertebral level. These sequelae can manifest as chronic pain, motor weakness, sensory deficits, or autonomic dysfunction that persist after the initial injury has healed.

Apply this code when documenting conditions that are residual effects of a past, unspecified T1 spinal cord injury. This is appropriate for follow-up encounters where the patient is being treated for ongoing problems directly attributable to the original trauma, rather than the acute injury itself.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, paralysis).
• Ensure documentation clearly links the current condition to a previous T1 spinal cord injury.
• This code is for sequela; do not use it for acute or initial injury encounters.
