2025 ICD-10-CM code G31.84
(Valid) Effective Date: N/A Revision Date: N/A Diseases of the nervous system - Other degenerative diseases of the nervous system 6 Feed
Mild cognitive impairment of uncertain or unknown etiology.
Medical necessity is established by documenting the presence of cognitive decline beyond normal aging that impacts daily function.This typically involves cognitive testing and assessment of functional abilities.
Diagnosis involves assessing medical history, symptoms, mental status, and performing physical and neurological exams.Additional tests may be done to rule out other conditions. Treatment may involve medication or therapies to address specific symptoms like memory loss.
In simple words: This diagnosis means someone has slightly more trouble with memory and thinking than other people their age, but they can still do everyday tasks.
This code signifies a mild decline in cognitive abilities, such as memory and thinking, that is more significant than typical age-related changes but does not interfere with daily functioning.The underlying cause of the impairment is not known.
Example 1: A 68-year-old patient presents with increasing forgetfulness, particularly with recent events and appointments. After ruling out other causes, the physician diagnoses mild cognitive impairment., A 75-year-old individual reports difficulty finding words and recalling names. Cognitive testing reveals mild impairment, but daily functioning remains intact. G31.84 is used to document the diagnosis., A patient with a history of mild cognitive decline undergoes further evaluation.No specific underlying cause is identified, so the diagnosis of mild cognitive impairment is maintained, using code G31.84.
Documentation should include details of the cognitive assessment, including specific areas of impairment, impact on daily life, and results of any diagnostic tests performed to rule out other conditions. Medical history, including any relevant medical or psychiatric conditions, should also be documented.
** It's important to distinguish G31.84 from other, more specific codes related to cognitive impairment due to known conditions. As of today's date, November 30, 2024, this information is current, but coding guidelines and descriptions can be subject to change.
