Late effect of injury to other and unspecified nerve

This code signifies a residual condition or complication arising from a past injury to any nerve not specifically classified elsewhere. It indicates that the initial nerve injury has resolved, but its lasting effects, such as chronic pain, weakness, or sensory deficits, persist. This code is used when the sequela, not the acute injury, is the focus of treatment.

Use this code when documenting a patient presenting with long-term neurological impairments directly attributable to a previous nerve trauma. This applies to conditions like post-traumatic neuropathy, chronic radiculopathy from an old fracture, or persistent paresthesia following a laceration, after the acute phase of the original injury has passed. Documentation should clearly link the current neurological deficit to a specific past injury.

• Always sequence this code after the code identifying the specific late effect (e.g., chronic pain, muscle weakness).
• Ensure documentation specifies the nature of the original injury and the resulting neurological sequela.
• Do not use for acute nerve injuries or ongoing treatment of the initial injury itself.
