I/I react d/t implnt elec nstim of prph nrv, lead, init

This code signifies an infection or inflammatory response specifically caused by the electrode (lead) component of an implanted electronic neurostimulator targeting a peripheral nerve. The patient is presenting for the initial treatment of this complication.

Apply this code when a patient with a peripheral nerve stimulator presents with signs and symptoms of infection (e.g., redness, swelling, purulent discharge) or inflammation (e.g., pain, tenderness) localized around the implanted lead. This is appropriate for the first encounter where this specific complication is diagnosed and managed.

• Ensure the documentation clearly specifies the complication is related to the electrode/lead of the neurostimulator, not the pulse generator.
• Confirm the neurostimulator is implanted in a peripheral nerve to differentiate from spinal or central nervous system devices.
• The "A" at the end indicates an initial encounter for this condition; select a subsequent or sequela encounter code for follow-up care.
