Mechanical entropion of right upper eyelid

This code signifies an inward turning of the margin of the right upper eyelid, specifically due to a mechanical cause. This mechanical force could be from scarring, inflammation, or other structural changes that physically pull the eyelid margin inward, causing the lashes to rub against the cornea.

Apply this code when documentation clearly indicates entropion of the right upper eyelid is due to a mechanical factor, such as cicatrix from trauma, surgery, or chronic inflammation. The physician's notes should specify the mechanical etiology and the affected eyelid.

• Differentiate from spastic entropion (H02.01-) and other forms of entropion.
• Ensure laterality (right upper eyelid) is explicitly documented.
• Look for documentation of the underlying mechanical cause if available, and code it additionally if appropriate.
