ICD 10 Code For Dementia – F03

Dementia is one of the most progressive and debilitating diseases that a person can suffer from. It is characterized by a decline in cognitive function and abilities, which can interfere with a person’s daily life and activities. There is no known cure for dementia, and it is currently ranked as the sixth leading cause of death in the world. In this blog post, we will explore the ICD 10 code for dementia, as well as its symptoms, causes, and treatments.

What is Dementia?

Dementia is a broad category of brain diseases that cause a long-term and often gradual decrease in the ability to think and remember. Dementia affects people of all ages, but is most common in older adults.

There are many different types of dementia, each with its own set of symptoms. The most common type of dementia is Alzheimer’s disease, which accounts for 60-80% of all cases. Other types include Lewy body dementia, frontotemporal dementia, and vascular dementia.

Dementia is characterized by impaired thinking, memory, and communication abilities. These abilities may decline slowly or quickly, and they can vary from mild to severe. People with mild dementia may experience occasional memory lapses, while people with severe dementia may lose the ability to speak or recognize loved ones.

There is no one test that can diagnose all types of dementia. Instead, doctors will use a combination of medical history, physical exam, neurological tests, and brain imaging to make a diagnosis. There is no cure for dementia, but there are treatments available to help manage symptoms and slow the progression of the disease.

The Different Types of Dementia

There are many types of dementia, each with its own set of symptoms and prognosis. The most common form of dementia is Alzheimer’s disease, which accounts for 60-80% of all cases. Other types of dementia include Lewy body dementia, frontotemporal dementia, and vascular dementia.

Alzheimer’s disease is characterized by the gradual loss of cognitive function, including memory, language, and executive function. Lewy body dementia is similar to Alzheimer’s disease in that it also causes cognitive decline, but patients with Lewy body dementia also experience visual hallucinations and fluctuations in alertness and attention. Frontotemporal dementia affects the frontal and temporal lobes of the brain, resulting in changes in personality and behavior as well as language difficulties. Vascular dementia occurs when there is damage to the blood vessels supplying the brain, leading to problems with cognition, executive function, and motor skills.

While there is no cure for any type of dementia, early diagnosis and treatment can help slow the progression of the disease and improve quality of life for patients and their caregivers.

Causes of Dementia

There are many possible causes of dementia, with the most common being Alzheimer’s disease. Other causes include Lewy body dementia, frontotemporal dementia, and vascular dementia. Dementia can also be caused by a combination of factors, such as Alzheimer’s and Lewy body dementia.

Alzheimer’s disease is the most common cause of dementia, accounting for 60-80% of cases. Alzheimer’s is a degenerative brain disease that leads to memory loss, changes in thinking and behaviour, and eventually death. The cause of Alzheimer’s is not fully understood, but it is believed to be a combination of genetic and lifestyle factors.

Lewy body dementia is the second most common form of dementia, accounting for 10-20% of cases. Lewy bodies are abnormal structures that build up in the brain cells of people with this condition. They cause problems with thinking, movement, behaviour, and sleep. People with Lewy body dementia often have hallucinations and delusions.

Frontotemporal dementia accounts for 5-10% of all cases of dementias. This type of dementia affects the frontal and temporal lobes of the brain – areas that control language, behaviour, and decision making. People with frontotemporal dementia may change dramatically in their personality and behaviour. They may become impulsive or act inappropriately in social situations.

Vascular dementia is caused by damage to the blood vessels in the brain.

Symptoms of Dementia

There are a variety of symptoms that may indicate someone is experiencing dementia. These can vary depending on the individual, and the stage of dementia. However, some common symptoms include:

-Memory loss: This is usually one of the first things to be noticed. Those with dementia may forget recent events, or have trouble remember people’s names or faces.

-Difficulty communicating: This can manifest as struggling to find the right words, or repeating oneself.

-Confusion: One may become easily confused, particularly about time and place. They may also have trouble following conversations or directions.

-Changes in mood and behavior: It’s not uncommon for those with dementia to experience depression, anxiety, irritability, or apathy. They may also act out in ways that are unusual for them.

What is the ICD 10 Code For Dementia?

ICD 10 Code For Dementia

The ICD code for dementia is F03. This code is used to indicate a diagnosis of dementia, which is a general term for memory loss and other cognitive impairments. Dementia can be caused by a variety of conditions, including Alzheimer’s disease, stroke, and head injury.

Includes (Presenile)Code
Dementia NOS
Psychosis NOS
Primary degenerative dementia NOS


Includes Code
NOS depressed or paranoid type
psychosis NOS

Use additional code, if desired, to indicate delirium or acute confusional state superimposed on dementia.

Senility NOS(R54)

How to Diagnose Dementia

To make a diagnosis of dementia, a doctor will carry out a clinical assessment, which usually involves:

talking to the person with dementia and their family or carers about their symptoms and how these have changed over time

asking about their medical history and any other health conditions they may have

carrying out a physical examination

arranging for some tests to be carried out, such as blood tests and scans.

The doctor may also refer the person with dementia to a specialist for further assessment.

Treatment for Dementia

There is no one-size-fits-all approach to treating dementia, as the condition can vary greatly from person to person. However, there are some general treatment strategies that may be effective in managing the symptoms of dementia.

The most important thing to remember when treating dementia is that the goal is to improve quality of life for the individual, not to cure the condition. In many cases, treatments will focus on managing symptoms and supporting caregivers.

There are a number of medications that can be used to treat the symptoms of dementia, including cholinesterase inhibitors and memantine. These drugs can help improve memory and cognition, as well as slow the progression of the condition.

In addition to medication, there are a number of non-pharmacological approaches that can be helpful in treating dementia. These include cognitive stimulation therapies, which aim to improve thinking and memory skills, and reminiscence therapy, which uses memories to promote well-being.

Prevention of Dementia

There are many things that individuals can do to prevent the onset of dementia. One of the most important things is to maintain good physical health. This means exercising regularly, eating a healthy diet, and getting adequate sleep.

It is also important to keep mentally active. This can be done by engaging in activities that challenge the brain, such as puzzles, Sudoku, and crosswords. Social interaction is also important for cognitive health, so it is vital to stay connected with friends and family.

If you have any concerns about your memory or thinking abilities, it is important to see a doctor for an assessment. Early diagnosis and treatment of conditions that can lead to dementia, such as Alzheimer’s disease and Lewy body dementia, can improve quality of life and potentially slow the progression of the disease.


The ICD 10 code for dementia is a useful tool for healthcare professionals to use when diagnosing and treating patients with this condition. However, it is important to remember that the code is only a guide and should not be used as a substitute for professional medical advice. If you are concerned about your own or someone else’s mental health, please contact a qualified healthcare professional for further assistance.
