Breakdown of balloon (counterpulsation) device, subs

This code signifies a mechanical failure of an intra-aortic balloon pump (IABP) that has been previously implanted. This breakdown refers to issues such as a ruptured balloon, catheter fracture, or other structural defects preventing the device from functioning correctly. The "subsequent encounter" indicates that the patient is receiving care for this complication after the initial treatment phase.

Use this code when a patient presents for follow-up care, evaluation, or management of a mechanical malfunction of their previously placed IABP. This includes situations where the patient is admitted for repair or replacement of the faulty device, or for complications directly arising from the device's mechanical failure.

• Ensure documentation clearly specifies a mechanical breakdown of the IABP, not an infection or other non-mechanical complication.
• Verify the encounter is for subsequent care related to the breakdown, not the initial diagnosis or insertion.
• Always code with an external cause code (e.g., Y70.0) to identify the type of medical device associated with the adverse event.
