Paralytic lagophthalmos unspecified eye, unspecified eyelid

This code signifies an inability to fully close the eyelid due to paralysis of the orbicularis oculi muscle, without specifying which eye or eyelid is affected. This condition can lead to corneal exposure and subsequent complications if left unaddressed.

Apply this code when documentation indicates paralytic lagophthalmos but does not specify laterality (right or left eye) or the specific eyelid involved (upper or lower). This is typically used when the physician notes "paralytic lagophthalmos" without further detail on the affected side.

• Avoid using this code if the laterality (right or left eye) is documented; instead, choose a more specific code from the H02.23 series.
• Ensure the documentation clearly states "paralytic lagophthalmos" and not just general lagophthalmos, which has different underlying causes.
• Consider sequencing this code after any underlying neurological condition causing the paralysis, if known and documented.
