2025 ICD-10-CM code G30.9
(Active) Effective Date: N/A Diseases of the nervous system - Other degenerative diseases of the nervous system 6 Feed
Alzheimer's disease, unspecified. This code is used when the type of Alzheimer's disease (early-onset, late-onset, or other) is not specified by the provider.
Modifiers are generally not applicable to ICD-10-CM diagnosis codes like G30.9.
Medical necessity for services related to Alzheimer's disease is established by the documented presence of cognitive decline impacting the patient's daily life and requiring medical intervention. The specific services deemed medically necessary will depend on the individual patient's needs and the stage of their disease.
Diagnosis is typically made based on the patient's medical history, signs, symptoms, physical and psychological evaluation, and standardized tests of memory. Further investigations, such as laboratory studies and imaging (CT, MRI, SPECT, or PET), might be necessary to rule out other causes of dementia.Treatment focuses on managing symptoms and may include medications (like donepezil, rivastigmine, galantamine, and memantine) and behavioral management strategies.
In simple words: This code indicates that a person has Alzheimer's disease, but the doctor hasn't specified what kind it is (like if it started early or late in life).
Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by a decline in memory and other cognitive functions.This code, G30.9, is used when the physician does not specify whether the AD is early-onset (occurring before age 65), late-onset (occurring after age 65), or another specific type of AD.It encompasses presenile and senile forms of Alzheimer's disease.
Example 1: A 75-year-old patient presents with gradual memory loss and difficulty performing familiar tasks. The physician diagnoses Alzheimer's disease but does not specify the onset as early or late. G30.9 is used., A 55-year-old individual exhibits progressive cognitive decline. After a thorough evaluation, Alzheimer's disease is diagnosed, but further details on the specific type of AD are not documented.G30.9 is applicable., A patient with existing dementia undergoes additional testing and is found to have Alzheimer's disease as an underlying cause. The physician does not specify the type of AD. G30.9 should be used in conjunction with the appropriate code from category F02 (Dementia in other diseases classified elsewhere).
Documentation should include details of the patient's cognitive decline, including specific examples of memory loss, behavioral changes, and functional impairments. Results of cognitive assessments, laboratory tests, and imaging studies should also be documented.If a specific type of Alzheimer's disease is identified, it should be clearly stated.
** It's important to emphasize that a diagnosis of Alzheimer's disease should be made by a qualified medical professional after a thorough evaluation.The information provided here is for coding purposes and should not be interpreted as medical advice.
