Brkdwn unsp cardiac and vascular devices and implants, subs

This code signifies a mechanical failure or malfunction of an unspecified cardiac or vascular device or implant that has been previously placed. It indicates that the patient is presenting for follow-up care related to this breakdown, rather than the initial treatment. The nature of the device or implant is not specified.

Apply this code when a patient returns for evaluation or management of a known mechanical issue with a cardiac or vascular device, such as a pacemaker, defibrillator, stent, or vascular graft, where the specific type of device is not documented. This is appropriate for subsequent visits after the initial diagnosis and treatment of the device malfunction.

• Ensure documentation clearly states a "mechanical breakdown" and not an infection or other complication.
• Confirm this is a "subsequent encounter" for the device issue, not the initial presentation.
• Only use when the specific cardiac or vascular device or implant is not identified in the medical record.
