Mech compl of cardiac pulse generator (battery), init encntr

This code signifies a mechanical issue with the battery component of an implanted cardiac pulse generator, such as a pacemaker or defibrillator. These complications are not related to lead malfunction and can include problems like battery displacement, erosion through the skin, or internal damage to the battery itself.

Use this code when a patient presents with a newly identified or treated mechanical complication specifically affecting the battery of their cardiac pulse generator. This applies to initial evaluations, diagnostic workups, and interventions for the complication.

• Ensure documentation clearly specifies the complication is related to the battery and not other components like leads or the generator body.
• Confirm the encounter is the initial treatment for this specific complication. Subsequent encounters would use a different seventh character.
• Distinguish from electrical or software malfunctions, which are coded differently.
