Paralytic ectropion of right lower eyelid

This code describes an outward turning of the lower eyelid margin on the right side, specifically caused by paralysis of the orbicularis oculi muscle. This paralysis prevents the eyelid from maintaining proper contact with the eyeball, leading to exposure of the conjunctiva.

Use this code when documentation clearly indicates paralytic ectropion affecting the right lower eyelid. This condition is often observed in cases of facial nerve palsy (Bell's palsy) or other neuropathies affecting the seventh cranial nerve. Documentation should specify the laterality and the paralytic etiology.

• Differentiate from cicatricial (H02.13-) or spastic (H02.14-) ectropion, which have different underlying causes.
• Ensure the documentation specifies "paralytic" and the correct laterality (right lower eyelid).
• Consider coding any underlying neurological condition causing the paralysis, such as facial nerve palsy, as a primary diagnosis if applicable.
