Code Classification

  • Mental and behavioural disorders
    (F01–F99)
    • Mental disorders due to known physiological conditions
      (F01-F09)
      • Dementia in other diseases classified elsewhere
        (F02)

F02 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of dementia in other diseases classified elsewhere. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Dementia in other diseases classified elsewhere

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.

  • Major neurocognitive disorder in other diseases classified elsewhere

Code First

Code First
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
  • the underlying physiological condition, such as:
  • Alzheimer's G30
  • cerebral lipidosis E75.4
  • Creutzfeldt-Jakob disease A81.0
  • dementia with Lewy bodies G31.83
  • dementia with Parkinsonism G31.83
  • epilepsy and recurrent seizures G40
  • frontotemporal dementia G31.09
  • hepatolenticular degeneration E83.01
  • human immunodeficiency virus HIV disease B20
  • Huntington's disease G10
  • hypercalcemia E83.52
  • hypothyroidism, acquired E00 E03
  • intoxications T36 T65
  • Jakob-Creutzfeldt disease A81.0
  • multiple sclerosis G35
  • neurosyphilis A52.17
  • niacin deficiency pellagra E52
  • Parkinson's disease G20
  • Pick's disease G31.01
  • polyarteritis nodosa M30.0
  • prion disease A81.9
  • systemic lupus erythematosus M32
  • traumatic brain injury S06
  • trypanosomiasis B56 B57
  • vitamin B deficiency E53.8

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.
  • mild neurocognitive disorder due to known physiological condition with or without behavioral disturbance F06.7

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.

Patient Education


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?

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

  • A medical history, which includes asking about your symptoms
  • A physical exam
  • Tests of your thinking, memory, and language abilities
  • Other tests, such as blood tests, genetic tests, and brain scans
  • 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.
