Mechanical ptosis of right eyelid

This code signifies a drooping of the upper eyelid on the right side that is caused by a physical obstruction or structural abnormality, rather than a neurological or muscular dysfunction. This mechanical interference prevents the eyelid from opening fully, potentially impairing vision.

Use this code when documentation clearly indicates a physical cause for right eyelid ptosis, such as an eyelid tumor, chalazion, scar tissue, or significant edema. The physician's notes should specify "mechanical ptosis" or describe a physical impediment to eyelid elevation.

• Differentiate from H02.414 (paralytic ptosis) or H02.417 (myogenic ptosis) by identifying the underlying cause.
• Always code the underlying cause of the mechanical ptosis (e.g., tumor, chalazion) in addition to this code.
• Ensure laterality is correctly identified; this code is specific to the right eyelid.
