Code Navigator:

F03.90 is a billable diagnosis code used to specify a medical diagnosis of unspecified dementia, unspecified severity, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2025 through September 30, 2026.

The code F03.90 is applicable to adult patients aged 15 through 124 years inclusive. It is clinically and virtually impossible to use this code on a patient outside the stated age range.

Unspecified diagnosis codes like F03.90 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

The following list of clinical terms are approximate synonyms, alternative descriptions, or common phrases that might be used by patients, healthcare providers, or medical coders to describe the same condition. These synonyms and related diagnosis terms are often used when searching for an ICD-10 code, especially when the exact medical terminology is unclear. Whether you're looking for lay terms, similar diagnosis names, or common language alternatives, this list can help guide you to the correct ICD-10 classification.

Clinical Classifications group individual ICD-10-CM diagnosis codes into broader, clinically meaningful categories. These categories help simplify complex data by organizing related conditions under common clinical themes.

They are especially useful for data analysis, reporting, and clinical decision-making. Even when diagnosis codes differ, similar conditions can be grouped together based on their clinical relevance. Each category is assigned a unique CCSR code that represents a specific clinical concept, often tied to a body system or medical specialty.

CCSR Code: NVS011

Inpatient Default: Y - Yes, default inpatient assignment for principal diagnosis or first-listed diagnosis.

Outpatient Default: Y - Yes, default outpatient assignment for principal diagnosis or first-listed diagnosis.

aberrant motor behaviors leading to inappropriate or purposeless activities in people with dementia. aberrant motor behaviors in people with dementia include aggression, agitation, refusal to care and wandering.

a neurologic condition associated with the acquired immunodeficiency syndrome and characterized by impaired concentration and memory, slowness of hand movements, ataxia, incontinence, apathy, and gait difficulties associated with hiv-1 viral infection of the central nervous system. pathologic examination of the brain reveals white matter rarefaction, perivascular infiltrates of lymphocytes, foamy macrophages, and multinucleated giant cells. (from adams et al., principles of neurology, 6th ed, pp760-1; n engl j med, 1995 apr 6;332(14):934-40)

a degenerative disease of the brain characterized by the insidious onset of dementia. impairment of memory, judgment, attention span, and problem solving skills are followed by severe apraxias and a global loss of cognitive abilities. the condition primarily occurs after age 60, and is marked pathologically by severe cortical atrophy and the triad of senile plaques; neurofibrillary tangles; and neuropil threads. (from adams et al., principles of neurology, 6th ed, pp1049-57)

a degenerative disorder affecting upper motor neurons in the brain and lower motor neurons in the brain stem and spinal cord. disease onset is usually after the age of 50 and the process is usually fatal within 3 to 6 years. clinical manifestations include progressive weakness, atrophy, fasciculation, hyperreflexia, dysarthria, dysphagia, and eventual paralysis of respiratory function. pathologic features include the replacement of motor neurons with fibrous astrocytes and atrophy of anterior spinal nerve roots and corticospinal tracts. (from adams et al., principles of neurology, 6th ed, pp1089-94)

a familial, cerebral arteriopathy mapped to chromosome 19q12, and characterized by the presence of granular deposits in small cerebral arteries producing ischemic stroke; pseudobulbar palsy; and multiple subcortical infarcts (cerebral infarction). cadasil is an acronym for cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy. cadasil differs from binswanger disease by the presence of migraine with aura and usually by the lack of history of arterial hypertension. (from bradley et al, neurology in clinical practice, 2000, p1146)

an acquired organic mental disorder with loss of intellectual abilities of sufficient severity to interfere with social or occupational functioning. the dysfunction is multifaceted and involves memory, behavior, personality, judgment, attention, spatial relations, language, abstract thought, and other executive functions. the intellectual decline is usually progressive, and initially spares the level of consciousness.

loss of higher cortical functions with retained awareness due to multiple cortical or subcortical cerebral infarction. memory, judgment, attention span, and impulse control are often impaired, and may be accompanied by pseudobulbar palsy; hemiparesis; reflex abnormalities, and other signs of localized neurologic dysfunction. (from adams et al., principles of neurology, 6th ed, p1060)

an imprecise term referring to dementia associated with cerebrovascular disorders, including cerebral infarction (single or multiple), and conditions associated with chronic brain ischemia. diffuse, cortical, and subcortical subtypes have been described. (from gerontol geriatr 1998 feb;31(1):36-44)

the most common clinical form of frontotemporal lobar degeneration, this dementia presents with personality and behavioral changes often associated with disinhibition, apathy, and lack of insight.

a neurodegenerative disease characterized by dementia, mild parkinsonism, and fluctuations in attention and alertness. the neuropsychiatric manifestations tend to precede the onset of bradykinesia, muscle rigidity, and other extrapyramidal signs. delusions and visual hallucinations are relatively frequent in this condition. histologic examination reveals lewy bodies in the cerebral cortex and brain stem. senile plaques and other pathologic features characteristic of alzheimer disease may also be present. (from neurology 1997;48:376-380; neurology 1996;47:1113-1124)

tests designed to assess various aspects of neurocognitive function or dementia.

dementias caused by multiple etiologies, e.g., alzheimer disease, and vascular dementia and/or lewy body disease.

a rare form of dementia that is sometimes familial. clinical features include aphasia; apraxia; confusion; anomia; memory loss; and personality deterioration. this pattern is consistent with the pathologic findings of circumscribed atrophy of the poles of the frontal lobe and temporal lobe. neuronal loss is maximal in the hippocampus, entorhinal cortex, and amygdala. some ballooned cortical neurons contain argentophylic (pick) bodies. (from brain pathol 1998 apr;8(2):339-54; adams et al., principles of neurology, 6th ed, pp1057-9)

cognitive impairment or functional decline after a surgical procedure.

a group of genetic, infectious, or sporadic degenerative human and animal nervous system disorders associated with abnormal prions. these diseases are characterized by conversion of the normal prion protein to an abnormal configuration via a post-translational process. in humans, these conditions generally feature dementia; ataxia; and a fatal outcome. pathologic features include a spongiform encephalopathy without evidence of inflammation. the older literature occasionally refers to these as unconventional slow virus diseases. (from proc natl acad sci usa 1998 nov 10;95(23):13363-83)

a severe emotional disorder of psychotic depth characteristically marked by a retreat from reality with delusion formation, hallucinations, emotional disharmony, and regressive behavior.

heterogeneous group of neurodegenerative disorders characterized by frontal and temporal lobe atrophy associated with neuronal loss, gliosis, and dementia. patients exhibit progressive changes in social, behavioral, and/or language function. multiple subtypes or forms are recognized based on presence or absence of tau protein inclusions. ftld includes three clinical syndromes: frontotemporal dementia, semantic dementia, and primary progressive nonfluent aphasia.

diminished or impaired mental and/or intellectual function.

subjectively experienced sensations in the absence of an appropriate stimulus, but which are regarded by the individual as real. they may be of organic origin or associated with mental disorders.

the presence of dementia in an individual younger than age sixty five.

loss of intellectual abilities in an elderly person, interfering with this person's activities.

This is a direct match with no additional mapping qualifiers. The absence of a flag generally means the mapping is considered exact or precise. In other words, the ICD-10 code maps cleanly to the ICD-9 code without qualification, approximation, or needing multiple codes.

Dementia

What is dementia?

Dementia is a loss of mental functions that is severe enough to affect your daily life and activities. These functions include:

It is normal to become a bit more forgetful as you age. But dementia is not a normal part of aging. It is a serious disorder that interferes with your daily life.

What are the types of dementia?

The most common types of dementia are known as neurodegenerative disorders. These are diseases in which the cells of the brain stop working or die. They include:

Other conditions can cause dementia or dementia-like symptoms, including:

Who is at risk for dementia?

Certain factors can raise your risk for developing dementia, including:

What are the symptoms of dementia?

The symptoms of dementia can vary, depending on which parts of the brain are affected. Often, forgetfulness is the first symptom. Dementia also causes problems with the ability to think, problem solve, and reason. For example, people with dementia may:

Some people with dementia cannot control their emotions and their personalities may change. They may become apathetic, meaning that they are no longer interested in normal daily activities or events. They may lose their inhibitions and stop caring about other peoples' feelings.

Certain types of dementia can also cause problems with balance and movement.

The stages of dementia range from mild to severe. In the mildest stage, it is just beginning to affect a person's functioning. In the most severe stage, the person is completely dependent on others for care.

How is dementia diagnosed?

Your health care provider may use many tools to make a diagnosis:

What are the treatments for dementia?

There is no cure for most types of dementia, including Alzheimer's disease and Lewy body dementia. Treatments may help to maintain mental function longer, manage behavioral symptoms, and slow down the symptoms of disease. They may include:

Can dementia be prevented?

Researchers have not found a proven way to prevent dementia. Living a healthy lifestyle might influence some of your risk factors for dementia.
