2025 ICD-10-CM code F03.90
(Active) Effective Date: N/A Revision Date: N/A Mental disorders due to known physiological conditions - Unspecified dementia, unspecified severity Chapter 5: Mental, Behavioral and Neurodevelopmental disorders (F01-F99) Feed
Unspecified dementia without behavioral disturbance.This diagnosis is used when the provider documents dementia but doesn't specify the type, and there are no behavioral changes like delusions or agitation.
Medical necessity for services related to dementia is based on the documented impact of cognitive decline on the patient's ability to function safely and independently. Ongoing monitoring and management are often required.
Diagnosis of dementia involves assessment of cognitive decline, functional impairment, and ruling out other causes. This includes taking a patient history, physical and neurological exams, cognitive testing, and often brain imaging.

- Mental disorders due to known physiological conditions (F01-F09)
In simple words: This refers to a general form of dementia where the specific type isn't known. The person experiences memory loss along with other thinking problems, but doesn't have behavioral issues like agitation or hallucinations.
Unspecified dementia, unspecified severity, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety. Forgetfulness combined with at least one other cognitive impairment (e.g., language, movement, sensory recognition, planning, abstract thought) without behavioral changes (e.g., delusions, hallucinations, agitation, aggression).
Example 1: A 75-year-old patient presents with gradual memory loss and difficulty with daily tasks. The physician diagnoses dementia but further testing is needed to determine the specific type., An elderly patient exhibits cognitive decline but lacks the behavioral disturbances often associated with specific dementias like Alzheimer's., A patient's family reports memory problems and confusion. Initial evaluation suggests dementia, but the physician uses this code while awaiting results of further diagnostic tests.
Documentation should include evidence of cognitive decline, impact on daily functioning, and exclusion of other medical or psychiatric conditions that could explain the symptoms. Details of cognitive assessments, neurological exam, and any imaging studies should be included.Consider documenting any type of associated cognitive disorder.
** Excludes1: senility NOS (R41.81). Excludes2: mild memory disturbance due to known physiological condition (F06.8); senile dementia with delirium or acute confusional state (F05).For accurate documentation and coding use iFrameAI.
