Breakdown (mechanical) of implnt elec nstim, generator, subs

This code signifies a mechanical failure of the generator component of an implanted electronic neurostimulator. It indicates that the device itself, rather than the lead or an infection, has malfunctioned, requiring attention during a subsequent patient encounter.

Apply this code when a patient presents with symptoms or diagnostic findings consistent with a mechanical breakdown of their neurostimulator's generator, such as loss of stimulation, erratic function, or device migration. This is appropriate for follow-up visits after the initial treatment or diagnosis of the breakdown.

• Ensure documentation specifies "mechanical breakdown" of the "generator" and not another component or type of complication.
• Verify this is a "subsequent encounter" for the management of the breakdown, not the initial diagnosis or an unrelated issue.
• Distinguish from other T85.1 codes that specify different types of complications or components of the neurostimulator.
