Total (external) ophthalmoplegia, right eye

This code describes a complete paralysis of the extraocular muscles affecting the right eye, resulting in an inability to move the eye in any direction. This condition is typically caused by damage to the oculomotor, trochlear, and abducens nerves, or the muscles themselves. Patients present with a fixed, immobile right eye and often experience diplopia.

Use this code when documentation clearly indicates total external ophthalmoplegia specifically affecting the right eye. This diagnosis is often supported by neurological examination findings demonstrating complete absence of extraocular movements in the right eye. It is commonly seen in cases of severe orbital trauma, cavernous sinus thrombosis, or extensive intracranial lesions impacting multiple cranial nerves.

• Ensure documentation specifies "total" or "complete" ophthalmoplegia and laterality (right eye).
• Distinguish from partial ophthalmoplegia or isolated cranial nerve palsies.
• Code any underlying cause or associated conditions, such as a tumor or trauma, as a primary diagnosis if applicable.
