Version 2020 Non-Billable Code

Not Valid for Submission

F03 is a "header" nonspecific and non-billable code code, consider using a code with a higher level of specificity for a diagnosis of unspecified dementia. The code is NOT valid for the year 2020 for the submission of HIPAA-covered transactions.

ICD-10:F03
Short Description:Unspecified dementia
Long Description:Unspecified dementia

Consider the following ICD-10 codes with a higher level of specificity:

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code F03:

Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Presenile dementia NOS
  • Presenile psychosis NOS
  • Primary degenerative dementia NOS
  • Senile dementia NOS
  • Senile dementia depressed or paranoid type
  • Senile psychosis NOS

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Type 2 Excludes

Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
  • mild memory disturbance due to known physiological condition F06.8
  • senile dementia with delirium or acute confusional state F05

Index to Diseases and Injuries

The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code F03 are found in the index:


Clinical Information

  • MENTAL STATUS AND DEMENTIA TESTS-. tests designed to assess various aspects of neurocognitive function or dementia.
  • ALZHEIMER DISEASE-. 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
  • AMYOTROPHIC LATERAL SCLEROSIS-. 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
  • DEMENTIA-. 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.
  • SCHIZOPHRENIA-. a severe emotional disorder of psychotic depth characteristically marked by a retreat from reality with delusion formation hallucinations emotional disharmony and regressive behavior.
  • DEMENTIA VASCULAR-. 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;311:36 44
  • DEMENTIA MULTI INFARCT-. 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
  • AIDS DEMENTIA COMPLEX-. 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;33214:934 40
  • PRION DISEASES-. 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;9523:13363 83

  • CADASIL-. 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
  • FRONTOTEMPORAL DEMENTIA-. 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.

Information for Patients


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

  • Memory
  • Language skills
  • Visual perception (your ability to make sense of what you see)
  • Problem solving
  • Trouble with everyday tasks
  • The ability to focus and pay attention

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 which 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

  • Alzheimer's disease, which is the most common form of dementia among older people. People with Alzheimer's have plaques and tangles in their brain. These are abnormal buildups of different proteins. Beta-amyloid protein clumps up and forms plaques in between your brain cells. Tau protein builds up and forms tangles inside the nerve cells of your brain. There is also a loss of connection between nerve cells in the brain.
  • Lewy body dementia, which causes movement symptoms along with dementia. Lewy bodies are abnormal deposits of a protein in the brain.
  • Frontotemporal disorders, which cause changes to certain parts of the brain:
    • Changes in the frontal lobe lead to behavioral symptoms
    • Changes in the temporal lobe lead to language and emotional disorders
  • Vascular dementia, which involves changes to the brain's blood supply. It is often caused by a stroke or atherosclerosis (hardening of the arteries) in the brain.
  • Mixed dementia, which is a combination of two or more types of dementia. For example, some people have both Alzheimer's disease and vascular dementia.

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

  • Creutzfeldt-Jakob disease, a rare brain disorder
  • Huntington's disease, an inherited, progressive brain disease
  • Chronic traumatic encephalopathy (CTE), caused by repeated traumatic brain injury
  • HIV-associated dementia (HAD)

Who is at risk for dementia?

Certain factors can raise your risk for developing dementia, including

  • Aging. This is the biggest risk factor for dementia.
  • Smoking
  • Uncontrolled diabetes
  • High blood pressure
  • Drinking too much alcohol
  • Having close family members who have dementia

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

  • Get lost in a familiar neighborhood
  • Use unusual words to refer to familiar objects
  • Forget the name of a close family member or friend
  • Forget old memories
  • Need help doing tasks that they used to do by themselves

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?

To make a diagnosis, your health care provider

  • Will ask about your medical history
  • Will do a physical exam
  • Will check your thinking, memory, and language abilities
  • May do tests, such as blood tests, genetic tests, and brain scans
  • May do a mental health evaluation to see whether a mental disorder is contributing to your symptoms

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

  • Medicines may temporarily improve memory and thinking or slow down their decline. They only work in some people. Other medicines can treat symptoms such as anxiety, depression, sleep problems, and muscle stiffness. Some of these medicines can cause strong side effects in people with dementia. It is important to talk to your health care provider about which medicines will be safe for you.
  • Occupational therapy to help find ways to more easily do everyday activities
  • Speech therapy to help with swallowing difficulties and trouble speaking loudly and clearly
  • Mental health counseling to help people with dementia and their families learn how to manage difficult emotions and behaviors. It can also help them plan for the future.
  • Music or art therapy to reduce anxiety and improve well-being

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.
