Breakdown of implnt elec nstim, generator, sequela

This code signifies a mechanical failure of the generator component of an implanted electronic neurostimulator, occurring as a long-term complication or sequela. This breakdown could involve issues such as lead fracture, device migration, or battery depletion that has led to a mechanical malfunction, rather than an electrical or infectious problem. The patient is experiencing ongoing effects from this past mechanical failure.

Use this code when documenting a patient presenting for evaluation or management of a persistent problem directly attributable to a mechanical breakdown of their neurostimulator generator that occurred in the past. This applies to situations where the initial acute event has resolved, but the patient continues to experience sequelae. Examples include chronic pain due to a dislodged generator, or ongoing neurological symptoms from a previously fractured lead.

• Requires a seventh character of 'S' to indicate sequela, meaning the patient is seen for the residual effects of a past mechanical breakdown.
• Distinguish from acute mechanical complications (A or D) or other types of neurostimulator complications (e.g., infection, electrical malfunction).
• Ensure documentation clearly links the current patient presentation to a previously occurring mechanical breakdown of the generator.
