Contact lens associated with adverse incidents

This code signifies an adverse event or complication directly linked to the use of a contact lens. It indicates that the contact lens itself, rather than a pre-existing condition, is the causative factor in the patient's presenting symptoms or injury. This includes issues arising from the lens material, design, or manufacturing.

Apply this code when a patient presents with an ocular condition, such as an infection, irritation, or injury, and the medical documentation clearly attributes the problem to the contact lens. This is appropriate for situations where the contact lens is identified as defective, improperly fitted, or otherwise directly responsible for the adverse incident.

• Always sequence this code as a secondary diagnosis, following the code for the specific adverse condition (e.g., keratitis, corneal abrasion).
• Ensure documentation explicitly states the contact lens as the cause of the adverse event.
• Do not use this code for complications arising from improper contact lens hygiene or patient non-compliance, which would typically fall under other external cause codes.
