Paralytic ectropion of left lower eyelid

This code signifies an outward turning of the lower eyelid margin on the left side, specifically caused by paralysis of the orbicularis oculi muscle. This condition prevents proper eyelid closure, leading to exposure of the conjunctiva and cornea. It results in symptoms such as tearing, irritation, and potential corneal damage.

Use this code when documentation clearly indicates paralytic ectropion affecting the patient's left lower eyelid. This typically arises from facial nerve palsy or other neurological conditions impacting the orbicularis oculi muscle. Supporting documentation should include a physical examination noting the outward turning of the left lower eyelid and evidence of underlying paralysis.

• Differentiate from cicatricial or senile ectropion, which have different etiologies and corresponding codes.
• Ensure laterality is accurately documented and coded (left lower eyelid).
• Code any underlying cause of the paralysis, such as facial nerve palsy, in addition to the ectropion.
