Eyelid retraction left lower eyelid

This code describes an abnormal elevation or pulling back of the left lower eyelid, exposing more of the globe than is typical. This condition can lead to ocular surface dryness, irritation, and potential vision impairment due to inadequate eyelid closure and tear film distribution.

Use this code when documentation specifies retraction of the lower eyelid on the left side. This typically occurs due to scarring, thyroid eye disease, or post-surgical complications. Documentation should clearly indicate the affected eyelid (lower) and laterality (left).

• Ensure documentation specifies "retraction" and not just "ectropion" or "lagophthalmos," as these are distinct conditions.
• Verify laterality; codes exist for the right, bilateral, and unspecified lower eyelids.
• Look for underlying causes, such as thyroid eye disease (e.g., H06.2x), which may be coded as a primary diagnosis with eyelid retraction as a secondary condition.
