Breakdown of implnt elec nstim of prph nrv lead, init

This code signifies a mechanical failure of an implanted electronic neurostimulator's peripheral nerve electrode (lead). This breakdown prevents the device from functioning as intended, leading to a loss of therapeutic stimulation for the patient. It specifically refers to the initial presentation or diagnosis of this mechanical issue.

Use this code when a patient presents with symptoms indicating a mechanical malfunction of their peripheral nerve stimulator lead, such as sudden loss of stimulation, intermittent stimulation, or pain at the lead site, and diagnostic testing confirms a mechanical breakdown. This applies to the first time this specific mechanical failure is documented and addressed.

• Ensure documentation clearly states "mechanical breakdown" of the lead, not just a general device malfunction.
• Confirm this is the initial encounter for this specific mechanical issue; subsequent encounters would use different seventh characters.
• Distinguish this from electrical or software malfunctions, which would be coded differently.
