Mechanical ptosis of bilateral eyelids

This code signifies a drooping of both upper eyelids caused by a physical obstruction or structural defect, rather than a neurological or muscular issue. This mechanical interference prevents the eyelids from opening fully, potentially impairing vision.

Apply this code when documentation clearly indicates bilateral eyelid ptosis due to a mechanical cause, such as a tumor, scar tissue, or significant edema. The physician's notes should specify the mechanical etiology affecting both eyes.

• Differentiate from other forms of ptosis (e.g., congenital, myopathic, neurogenic) which have distinct codes.
• Ensure documentation specifies "bilateral" involvement; unilateral mechanical ptosis uses different codes.
• Code the underlying mechanical cause (e.g., tumor, scar) in addition to the ptosis, if applicable.
