The ICD-10 code G90.3 refers to "Multi-system degeneration of the autonomic nervous system," a condition characterized by the progressive degeneration of autonomic nerves that can affect multiple systems within the body. This condition is part of a broader category of disorders affecting the autonomic nervous system (ANS), which regulates involuntary bodily functions such as heart rate, blood pressure, digestion, and temperature control.

Clinical Description

Overview of Multi-system Degeneration

Multi-system degeneration of the autonomic nervous system involves the deterioration of nerve cells that control autonomic functions. This degeneration can lead to a variety of symptoms that impact multiple organ systems, making diagnosis and management complex. The condition is often associated with neurodegenerative diseases, such as multiple system atrophy (MSA), which is characterized by a combination of autonomic dysfunction, parkinsonism, and ataxia.

Symptoms

Patients with G90.3 may experience a range of symptoms, including but not limited to:

• Cardiovascular Issues: Orthostatic hypotension (a drop in blood pressure upon standing), heart rate variability, and other cardiovascular dysregulations.
• Gastrointestinal Problems: Symptoms may include constipation, gastroparesis (delayed gastric emptying), and dysphagia (difficulty swallowing).
• Urinary Dysfunction: This can manifest as urinary incontinence, retention, or other bladder control issues.
• Temperature Regulation Issues: Patients may have difficulty regulating body temperature, leading to excessive sweating or heat intolerance.
• Sexual Dysfunction: This may include erectile dysfunction in men and decreased libido in both genders.

Diagnosis

Diagnosing multi-system degeneration of the autonomic nervous system typically involves a comprehensive clinical evaluation, including:

• Patient History: A detailed medical history to identify symptoms and their progression.
