Breakdown (mechanical) of umbrella device, initial encounter

This code signifies a mechanical failure or malfunction of an umbrella device, which is a type of occluder used to close patent foramen ovale (PFO) or atrial septal defects (ASD). This breakdown could involve a fracture, detachment, or other structural compromise of the device itself.

Use this code when a patient presents with symptoms or findings directly attributable to the mechanical failure of an implanted umbrella device. This applies to the initial assessment and treatment of the device malfunction, such as during a re-intervention or diagnostic workup.

• Always assign an additional code to specify the nature of the mechanical breakdown, if known (e.g., fracture, displacement).
• Ensure documentation clearly states the device involved is an "umbrella device" and not another type of cardiac occluder.
• The "A" seventh character indicates an initial encounter for this specific complication.
