Unspecified lagophthalmos left lower eyelid

This code describes an inability to completely close the left lower eyelid, where the specific cause or type of lagophthalmos is not documented. This can lead to corneal exposure, dryness, and potential damage due to inadequate protection and lubrication of the ocular surface.

Use this code when the physician's documentation explicitly states "lagophthalmos of the left lower eyelid" but does not specify the underlying etiology (e.g., paralytic, cicatricial, nocturnal). This code is appropriate when the documentation indicates the lower eyelid is affected, and the laterality is clearly left, without further detail on the type.

• Ensure the documentation specifies "lower eyelid" and "left" for accurate coding.
• Avoid using this code if a more specific type of lagophthalmos (e.g., paralytic, cicatricial) is documented; instead, use the appropriate subcategory.
• Always review the entire medical record for any additional information that might allow for a more specific code.
