Mechanical lagophthalmos right eye, upper and lower eyelids

This code signifies an inability to fully close the right eye due to a physical obstruction or restriction affecting both the upper and lower eyelids. This mechanical interference prevents proper eyelid apposition, potentially leading to corneal exposure and related complications.

Apply this code when documentation specifies mechanical lagophthalmos of the right eye, explicitly involving both the upper and lower eyelids. This condition is often seen following trauma, surgery, or in cases of tumor growth affecting eyelid movement.

• Ensure documentation clearly specifies "mechanical" lagophthalmos, not paralytic or cicatricial.
• Verify the laterality (right eye) and involvement of both upper and lower eyelids.
• Consider additional codes for underlying causes (e.g., tumor, trauma) or associated complications (e.g., corneal ulcer).
