Unspecified lagophthalmos right upper eyelid

This code describes an inability to fully close the right upper eyelid, where the specific cause or type of lagophthalmos has not been documented. This condition can lead to corneal exposure, dryness, and potential damage due to inadequate protection and lubrication of the eye.

Use this code when the physician's documentation clearly indicates lagophthalmos affecting the right upper eyelid, but the underlying etiology (e.g., paralytic, cicatricial, nocturnal) is not specified. This code is appropriate when the laterality and eyelid are known, but further diagnostic specificity is lacking.

• Ensure documentation specifies "right upper eyelid" to support this code; otherwise, an unspecified laterality or eyelid code may be more appropriate.
• If the cause of the lagophthalmos is known (e.g., facial nerve palsy), code the underlying condition first, followed by the lagophthalmos.
• Avoid using this code if a more specific type of lagophthalmos (e.g., paralytic, cicatricial) is documented; look for codes in the H02.2- subcategory.
