2022 ICD-10-CM Code G61.0

Guillain-Barre syndrome

Version 2021

Valid for Submission

ICD-10:G61.0
Short Description:Guillain-Barre syndrome
Long Description:Guillain-Barre syndrome

Code Classification

  • Diseases of the nervous system (G00–G99)
    • Polyneuropathies and other disorders of the peripheral nervous system (G60-G65)
      • Inflammatory polyneuropathy (G61)

G61.0 is a billable diagnosis code used to specify a medical diagnosis of guillain-barre syndrome. The code G61.0 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.

The ICD-10-CM code G61.0 might also be used to specify conditions or terms like acute infective polyneuritis, acute inflammatory demyelinating polyradiculoneuropathy, acute pure sensory neuropathy, acute sensory ataxic neuropathy, fisher's syndrome , guillain-barré syndrome, etc.

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code G61.0:

These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

Information for Patients


Guillain-Barre Syndrome

Guillain-Barre syndrome is a rare disorder that causes your immune system to attack your peripheral nervous system (PNS). The PNS nerves connect your brain and spinal cord with the rest of your body. Damage to these nerves makes it hard for them to transmit signals. As a result, your muscles have trouble responding to your brain. No one knows what causes the syndrome. Sometimes it is triggered by an infection, surgery, or a vaccination.

The first symptom is usually weakness or a tingling feeling in your legs. The feeling can spread to your upper body. In severe cases, you become almost paralyzed. This is life-threatening. You might need a respirator to breathe. Symptoms usually worsen over a period of weeks and then stabilize.

Guillain-Barre can be hard to diagnose. Possible tests include nerve tests and a spinal tap. Most people recover. Recovery can take a few weeks to a few years. Treatment can help symptoms, and may include medicines or a procedure called plasma exchange.

Guillain-Barré syndrome

Guillain-Barré syndrome is an autoimmune disorder that affects the nerves. Autoimmune disorders occur when the immune system malfunctions and attacks the body's own tissues and organs. In Guillain-Barré syndrome, the immune response damages peripheral nerves, which are the nerves that connect the central nervous system (the brain and spinal cord) to the limbs and organs. Specifically, the immune response affects a particular part of peripheral nerves called axons, which are the extensions of nerve cells (neurons) that transmit nerve impulses. Guillain-Barré syndrome can affect the neurons that control muscle movement (motor neurons); the neurons that transmit sensory signals such as pain, temperature, and touch (sensory neurons); or both. As a result, affected individuals can experience muscle weakness or lose the ability to feel certain sensations.

Muscle weakness or paralysis are the characteristic features of Guillain-Barré syndrome. The weakness often begins in the legs and spreads to the arms, torso, and face and is commonly accompanied by numbness, tingling, or pain. Additional signs and symptoms of the condition include difficulty swallowing and difficulty breathing. Occasionally, the nerves that control involuntary functions of the body such as blood pressure and heart rate are affected, which can lead to fluctuating blood pressure or an abnormal heartbeat (cardiac arrhythmia).

There are several types of Guillain-Barré syndrome, classified by the part of the peripheral nerve involved in the condition. The most common type of Guillain-Barré syndrome is acute inflammatory demyelinating polyradiculoneuropathy (AIDP). In AIDP, the immune response damages myelin, which is the covering that protects axons and promotes the efficient transmission of nerve impulses. In two other types of Guillain-Barré syndrome, acute motor axonal neuropathy (AMAN) and acute motor-sensory axonal neuropathy (AMSAN), the axons themselves are damaged by the immune response. In AMAN, only the axons of motor neurons are damaged. In AMSAN, the axons of sensory neurons are also damaged. Because of sensory nerve damage, affected individuals can lose the ability to sense the position of their limbs and can have abnormal or absent reflexes (areflexia).

Miller Fisher syndrome, another type of Guillain-Barré syndrome, involves cranial nerves, which extend from the brain to various areas of the head and neck. Miller Fisher syndrome is characterized by three features: weakness or paralysis of the muscles that move the eyes (ophthalmoplegia), problems with balance and coordination (ataxia), and areflexia. People with this condition can have other signs and symptoms common in Guillain-Barré syndrome, such as muscle weakness.

Guillain-Barré syndrome occurs in people of all ages. The development of the condition usually follows a pattern. Prior to developing the condition, most people with Guillain-Barré syndrome have a bacterial or viral infection. The first phase of Guillain-Barré syndrome, during which signs and symptoms of the condition worsen, can last up to four weeks, although the peak of the illness is usually reached in one to two weeks. During the second phase, called the plateau, signs and symptoms of Guillain-Barré syndrome stabilize. This phase can last weeks or months. During the recovery phase, symptoms improve. However, some people with Guillain-Barré syndrome never fully recover and can still experience excessive tiredness (fatigue), muscle weakness, or muscle pain.
