Mechanical ectropion of left lower eyelid

This code describes an outward turning of the lower eyelid margin on the left eye, specifically caused by a mechanical factor. This mechanical force prevents the eyelid from resting against the globe, leading to exposure of the conjunctiva and potential irritation.

Use this code when documentation specifies ectropion of the left lower eyelid due to a mechanical cause, such as a tumor, scar tissue, or edema. The physician's notes should clearly indicate the mechanical etiology and the affected eyelid.

• Differentiate from paralytic (H02.11-) or spastic (H02.13-) ectropion, which have different underlying causes.
• Ensure the laterality (left) and eyelid (lower) are explicitly documented to support this specific code.
• Code any underlying mechanical cause (e.g., tumor, scar) in addition to the ectropion.
