2025 ICD-10-CM code G31.9
(Active) Effective Date: N/A Diseases of the nervous system - Other degenerative diseases of the nervous system 6 Feed
Unspecified degenerative disease of the nervous system.
Medical necessity is established by the documented signs, symptoms, and clinical findings suggestive of a degenerative nervous system disorder. The documentation should clearly support the need for diagnostic testing and ongoing management of the condition.
Symptoms may include memory loss, cognitive decline, behavioral and personality changes, language disturbances, and movement disorders such as tremors, muscle stiffness, and slow movements. Diagnosis is based on medical history, physical and neurological examinations, and often involves ruling out other conditions through blood tests, urine tests, MRI, or CT scans. Treatment focuses on managing symptoms and may involve medication, physical therapy, occupational therapy, and speech therapy.
In simple words: This code represents a general category for degenerative diseases of the nervous system that haven't been specified.It's used when a doctor hasn't determined the exact type of degenerative disease a patient has.
Degenerative diseases of the nervous system are characterized by the progressive loss of function of neurons in the brain. This specific code is used when the provider does not document the patient's specific degenerative nervous system disease, making it an unspecified diagnosis within this category.
Example 1: A patient presents with gradual memory loss and difficulty with daily tasks. After extensive testing to rule out other conditions, the physician diagnoses a degenerative disease of the nervous system, but the specific type remains undetermined, thus G31.9 is used., An elderly patient exhibits progressive decline in cognitive function and changes in behavior. The physician suspects a degenerative neurological condition, but further specialized testing is required to pinpoint the exact diagnosis. In the meantime, G31.9 serves as a placeholder., A patient experiences tremors and muscle stiffness, along with some cognitive impairment. While Parkinson's disease is suspected, diagnostic confirmation is pending. G31.9 can be used until a definitive diagnosis is established.
Documentation should include a detailed medical history, physical and neurological exam findings, results of any diagnostic tests performed (e.g., blood tests, MRI, CT scan), and the physician's clinical rationale for suspecting a degenerative disease of the nervous system.
