Breakdown of cardiac pulse generator (battery), subs

This code indicates a mechanical failure of the battery component of an implanted cardiac pulse generator, such as a pacemaker or implantable cardioverter-defibrillator (ICD). This breakdown is not due to an infection or electrical malfunction, but rather a physical or structural issue with the battery itself.

Use this code when a patient presents for follow-up care, evaluation, or management of a previously identified mechanical breakdown of their cardiac pulse generator's battery. This applies to situations where the initial treatment or diagnosis has already occurred, and the patient is returning for further assessment or intervention related to the battery failure.

• Requires a seventh character of "D" for subsequent encounter.
• Distinguish from electrical or infectious complications of the device.
• Ensure documentation clearly specifies a mechanical issue with the battery, not the lead or other components.
