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

This code signifies a malfunction or adverse event related to the non-battery components of an implanted cardiac pulse generator, such as the device housing or connections, occurring during a follow-up encounter. It indicates that the device itself, rather than the leads or the battery, is experiencing a mechanical issue requiring further medical attention.

Apply this code when a patient presents for evaluation of symptoms or findings directly attributable to a mechanical problem with their cardiac pulse generator (excluding the battery) after the initial treatment phase. This includes issues like device migration, erosion through the skin, or a structural defect in the generator casing identified during a subsequent visit.

• Ensure documentation clearly specifies the mechanical complication is of the pulse generator and not the leads or battery.
• Verify that the encounter is for follow-up care related to the complication, indicated by the "D" seventh character.
• Consider additional codes for specific symptoms or further complications arising from the mechanical issue.
