Sixth [abducent] nerve palsy, right eye

This code signifies a paralysis or weakness of the sixth cranial nerve affecting the right eye. This nerve is responsible for the lateral movement of the eye, so its dysfunction results in the inability to abduct the right eye, often leading to horizontal double vision (diplopia).

Apply this code when documentation clearly indicates a diagnosis of abducens nerve palsy specifically impacting the right eye. This is typically supported by neurological examination findings such as impaired abduction of the right eye, esotropia (inward turning) of the right eye, and patient complaints of horizontal diplopia that worsens with gaze to the right.

• Ensure laterality is explicitly documented as "right eye" to support this specific code.
• Distinguish from other cranial nerve palsies affecting eye movement (e.g., oculomotor or trochlear nerve palsies).
• Look for an underlying cause (e.g., H53.2 for diplopia, or codes for trauma, tumor, or vascular events) to code as a secondary diagnosis if applicable.
