Breakdown of cardiac and vascular devices and implants, subs

This code signifies a mechanical failure or malfunction of a non-specified cardiac or vascular device or implant, such as a stent, graft, or pacemaker lead, that is not explicitly categorized elsewhere. It indicates that the device itself has physically broken down, fractured, or otherwise ceased to function correctly due to a mechanical issue.

This code is appropriate for subsequent encounters where a patient presents with symptoms or findings related to a mechanical breakdown of an implanted cardiac or vascular device, excluding pacemakers, defibrillators, or heart valves. Examples include a fractured vascular stent, a dislodged arterial graft, or a broken lead for a cardiac monitor. The "D" seventh character indicates that this is an encounter for routine care during the healing or recovery phase.

• Ensure the documentation clearly specifies a mechanical breakdown of the device, not an infection or other complication.
• Verify that the device is not a pacemaker, defibrillator, or heart valve, as those have more specific codes.
• Confirm that the encounter is for follow-up care or management of the breakdown after the initial treatment, as indicated by the "D" seventh character.
