Injury of trigeminal nerve, right side, sequela

This code signifies a long-term or late effect resulting from a previous injury to the right trigeminal nerve. Such sequelae can manifest as persistent pain, numbness, or altered sensation in the areas supplied by the right trigeminal nerve, including the face, jaw, and teeth.

Apply this code when documentation clearly indicates a residual condition directly attributable to an old injury of the right trigeminal nerve. This is appropriate for chronic symptoms like post-traumatic trigeminal neuralgia or persistent paresthesia following a past facial trauma or surgical complication affecting the nerve. The medical record must specify the right side and the sequela nature of the condition.

• Always ensure the documentation explicitly states "sequela" or "late effect" and links the current condition to a past injury of the trigeminal nerve.
• Do not use this code for acute trigeminal nerve injuries; those require codes from the acute injury section.
• Verify laterality (right side) is clearly documented; separate codes exist for the left side and unspecified side.
