Brkdwn unsp cardiac and vascular devices and implnt, sequela

This code signifies a long-term complication resulting from the mechanical failure of an unspecified cardiac or vascular device or implant. This breakdown is not due to infection, displacement, or other specified complications, but rather a structural or functional failure of the device itself. The "sequela" designation indicates that this is a late effect of the initial device failure.

Apply this code when documenting a patient presenting with ongoing issues directly attributable to a past mechanical breakdown of a cardiac or vascular implant, where the specific type of device or implant is not documented. This is appropriate for follow-up encounters addressing chronic problems stemming from such a failure, even if the device has since been removed or replaced.

• Ensure documentation clearly states the mechanical nature of the breakdown and that it's an unspecified cardiac or vascular device.
• This code is for sequelae; use an acute complication code if the breakdown is occurring during the current encounter.
• Always look for more specific codes if the type of cardiac or vascular device is known (e.g., pacemaker, stent).
