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

This code signifies a chronic or residual infectious or inflammatory complication arising from an implanted electronic neurostimulator lead specifically placed in a peripheral nerve. This includes conditions like persistent pain, nerve damage, or chronic infection that are direct long-term consequences of the lead's presence or a prior acute event. It represents the lasting effects rather than an active, acute infection or inflammation.

Use this code when documenting a patient presenting with ongoing symptoms or conditions that are a direct sequela of an infection or inflammatory reaction related to a peripheral nerve neurostimulator electrode. This applies to situations where the initial acute event has resolved, but its long-term effects persist. Examples include chronic neuropathy or scar tissue formation at the lead site due to a past infection.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, neuropathy).
• Ensure documentation clearly links the current condition to a past infection or inflammatory reaction of the peripheral nerve neurostimulator lead.
• Do not use this code for active, acute infections or inflammatory reactions; instead, refer to the acute infection codes within the T85.73- category.
