G63: Polyneuropathy in diseases classified elsewhere

Polyneuropathy in diseases classified elsewhere (G63) refers to a group of conditions where damage or disease affects peripheral nerves in more than one part of the body, and it is secondary to other systemic diseases. It's not a specific condition itself, but a symptom or complication that arises from various underlying conditions, such as diabetes, renal failure, or certain types of infections. Common symptoms often commence with weakness or unusual sensations, such as tingling or burning, typically in the hands and feet, and progression may lead to balance issues and difficulty in moving. As different kinds of nerves may be affected, symptoms can vary, but they mainly affect the sensory, motor, and autonomic systems. The disease progression depends on the root cause or disease linked with the onset of polyneuropathy.
