Mech compl of nervous sys device, implant or graft, sequela

This code signifies a lasting or residual problem resulting from a mechanical issue with a nervous system device, implant, or graft that is not otherwise specified. It indicates that the initial mechanical complication has resolved, but its effects persist as a sequela. This could involve chronic pain, neurological deficits, or other long-term consequences directly attributable to the past device malfunction.

Use this code when documenting a patient's current condition as a direct, long-term consequence of a previously treated or resolved mechanical complication of a nervous system device. This applies to situations where the device itself is no longer actively malfunctioning, but the patient continues to experience symptoms or impairments due to the prior event. Examples include chronic neuropathic pain following a dislodged spinal cord stimulator lead, or persistent weakness after a previously fractured shunt catheter.

• Always sequence this code after the code(s) for the specific sequela being treated or managed.
• Ensure documentation clearly links the current condition to a past mechanical complication of a nervous system device.
• Do not use this code for active, ongoing mechanical complications; use the acute complication codes (T85.6- without the 'S' seventh character) in those instances.
