2025 ICD-10-CM code G99.0
(Valid) Effective Date: N/A Diseases of the nervous system - Other disorders of the nervous system 6 Feed
Autonomic neuropathy in diseases classified elsewhere. Code first underlying disease.
Medical necessity for the evaluation and management of autonomic neuropathy is established by the presence of signs and symptoms such as orthostatic hypotension, gastrointestinal issues, urinary problems, and sweating abnormalities. The medical record should document the patient's symptoms, the impact on their daily life, and the need for interventions to manage the condition.
The autonomic nervous system (ANS) controls involuntary body functions such as heart rate, breathing, sweating, and digestion. Autonomic neuropathy occurs when these nerves are damaged due to underlying conditions like diabetes, Parkinson's disease, or autoimmune diseases. Symptoms can vary but often include dizziness, digestive problems, urinary incontinence, and sexual dysfunction. Diagnosis is based on medical history, symptoms, and physical examination, and treatment focuses on managing the underlying condition and providing symptomatic relief.
In simple words: Autonomic neuropathy means damage to the nerves that control automatic body functions like heart rate, digestion, and sweating. This code is used when the neuropathy is caused by another health problem, which should be coded first.
Autonomic neuropathy in diseases classified elsewhere refers to damage to the nerves of the autonomic nervous system (ANS) occurring as a result of an underlying disease classified elsewhere. The primary disease should be coded first.
Example 1: A patient with diabetes experiences dizziness upon standing and has digestive issues. After examination and testing, the physician diagnoses autonomic neuropathy due to diabetes. G99.0 is coded after the code for diabetes., A patient with Parkinson's disease presents with urinary incontinence and erectile dysfunction. The physician determines that these symptoms are due to autonomic neuropathy secondary to Parkinson's disease. G99.0 is coded after the code for Parkinson's disease., A patient with diagnosed amyloidosis experiences abnormal sweating and fluctuating heart rate during exercise. The physician attributes these findings to autonomic neuropathy related to the amyloidosis. G99.0 is used following the code for amyloidosis.
Documentation should clearly establish the presence of autonomic neuropathy and link it to the underlying disease. Symptoms, physical exam findings, and results of any diagnostic tests should be documented. The underlying disease should be clearly documented as the cause of the autonomic neuropathy.
