Injury of other specified nerves of thorax, sequela

This code signifies a long-term or residual effect resulting from a past injury to a specific nerve within the thoracic region, excluding the spinal cord and nerve roots. It indicates that the initial injury has resolved, but the patient continues to experience persistent symptoms or deficits directly attributable to that prior nerve damage.

Apply this code when documenting a patient presenting with chronic pain, sensory disturbances, motor weakness, or other neurological sequelae directly linked to a previously sustained injury of a named thoracic nerve (e.g., intercostal nerve, phrenic nerve) that is no longer acute. This is appropriate for follow-up encounters addressing these lasting effects.

• Always use in conjunction with a code identifying the specific nature of the sequela (e.g., chronic pain, muscle atrophy).
• Ensure documentation clearly links the current condition to a past thoracic nerve injury.
• Do not use for acute or subacute injuries; reserve for conditions where the initial injury has healed but residual effects persist.
