Cicatricial lagophthalmos right upper eyelid

This code describes the inability to fully close the right upper eyelid due to scarring or fibrous tissue contraction. This condition, known as cicatricial lagophthalmos, can lead to corneal exposure, dryness, and potential damage if left untreated.

Use this code when documentation explicitly states cicatricial lagophthalmos affecting the right upper eyelid. This typically arises from trauma, burns, infection, or prior surgery that has resulted in scar tissue formation preventing complete eyelid closure.

• Specify laterality (right, left, bilateral) and eyelid (upper, lower) when documenting lagophthalmos.
• Distinguish from paralytic lagophthalmos (e.g., due to facial nerve palsy) which has different coding.
• Look for underlying causes of the scarring, such as burns (T20-T32) or trauma (S00-S09), which may require additional coding.
