Breakdown of cardiac pulse generator (battery), init

This code signifies a mechanical failure of the battery component within an implanted cardiac pulse generator, such as a pacemaker or implantable cardioverter-defibrillator (ICD). This breakdown can lead to device malfunction and impact its ability to regulate heart rhythm.

Use this code when a patient presents with symptoms or diagnostic findings indicating a mechanical issue with the pulse generator's battery. This applies to the initial evaluation and treatment of such a breakdown, often requiring device interrogation or replacement.

• Ensure documentation clearly specifies a mechanical breakdown of the battery, not an electrical or software issue.
• Confirm this is the initial encounter for this specific breakdown; subsequent encounters would use a different seventh character.
• Always code the underlying reason for the pulse generator implantation, if known and relevant to the current encounter.
