Breakdown of balloon (counterpulsation) device, sequela

This code signifies a mechanical failure or malfunction of an intra-aortic balloon pump (IABP) that occurred in the past and is now presenting with residual effects or complications. It indicates that the device itself, designed to assist cardiac function, experienced a breakdown rather than a biological complication in the patient.

This code is appropriate for documenting long-term complications or sequelae directly attributable to a prior mechanical breakdown of an IABP. Examples include chronic issues arising from a previous balloon rupture, catheter damage, or pump malfunction that necessitated further intervention or ongoing management. It should be used when the acute event has passed, and the patient is experiencing a lasting impact.

• Ensure documentation clearly links the current condition to a past mechanical breakdown of the IABP.
• Do not use for acute, active mechanical breakdowns; those would typically be coded with the initial encounter (A) or subsequent encounter (D) seventh characters.
• Always review the patient's history to confirm the IABP breakdown was mechanical and not a biological complication.
