Paralytic lagophthalmos right lower eyelid

This code indicates an inability to completely close the right lower eyelid due to paralysis of the orbicularis oculi muscle. This paralytic condition results in exposure of the ocular surface, potentially leading to dryness and irritation.

Apply this code when documentation specifies paralytic lagophthalmos affecting the lower eyelid of the right eye. This condition is often associated with facial nerve palsy or other neurological deficits impacting eyelid function. Supporting documentation should clearly state the laterality and the specific eyelid affected.

• Ensure documentation specifies "paralytic" lagophthalmos; other forms of lagophthalmos (e.g., cicatricial) are coded differently.
• Verify laterality (right eye) and the specific eyelid (lower) are clearly documented.
• Consider co-reporting with codes for the underlying cause of the facial nerve paralysis, if known and documented.
