The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) is a crucial tool in healthcare for coding and classifying diagnoses. For dementia, a complex and multifaceted condition, accurate ICD-10 coding is essential for proper documentation, billing, and statistical tracking. Code F03.90, specifically, addresses a critical category within dementia diagnoses. This article delves into the specifics of ICD-10-CM code F03.90, providing a comprehensive understanding for healthcare professionals and anyone seeking clarity on dementia diagnosis coding.
What is ICD-10-CM Code F03.90?
ICD-10-CM code F03.90 is defined as “Unspecified dementia, unspecified severity, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety.” This code is designated as billable and specific, meaning it is a valid code for claiming reimbursement and provides a detailed level of diagnostic information. The code’s 2025 edition became effective on October 1, 2024, highlighting its current relevance in medical coding. It’s important to note that F03.90 is the American ICD-10-CM version, and international versions might have variations.

Decoding the Description of F03.90
Let’s break down each component of the F03.90 code description:
- Unspecified Dementia: This indicates that the specific type of dementia is not identified in the diagnosis. Dementia itself is not a single disease but a syndrome characterized by a decline in cognitive function. When “unspecified,” it means the medical documentation lacks the detail to classify the dementia further, such as Alzheimer’s disease, vascular dementia, or Lewy body dementia.
- Unspecified Severity: The severity of the dementia is also not specified. Dementia severity can range from mild to severe, impacting the individual’s functional abilities differently. “Unspecified severity” suggests that the degree of cognitive impairment is not documented to be categorized as mild, moderate, or severe within the coding.
- Without Behavioral Disturbance, Psychotic Disturbance, Mood Disturbance, and Anxiety: This is a critical part of the code. It explicitly states the absence of these common neuropsychiatric symptoms often associated with dementia. This means the patient does not exhibit significant behavioral issues like agitation or aggression, psychotic symptoms such as hallucinations or delusions, mood disturbances like depression, or anxiety disorders that are directly linked to the dementia.
Who Does ICD-10-CM Code F03.90 Apply To?
ICD-10-CM coding rules specify that F03.90 is applicable to adult patients aged 15 to 124 years inclusive. This age range underscores that dementia, while more prevalent in older adults, is not exclusively a condition of old age and can affect younger individuals as well.
Synonyms and Clinical Context of F03.90
Understanding the synonyms associated with F03.90 helps to further clarify its clinical application. Terms that are considered approximate synonyms for F03.90 include:
- Dementia NOS (Not Otherwise Specified): This is a direct equivalent, emphasizing the “unspecified” nature of the dementia.
- Organic Dementia: This older term refers to dementia caused by a physical or physiological disorder, as opposed to a psychiatric illness.
- Senile Dementia/Presenile Dementia: These terms relate to the onset of dementia, with “senile” traditionally referring to onset in older age and “presenile” to earlier onset. However, in modern usage and ICD-10-CM, these are often encompassed under broader dementia categories unless further specified.
- Mild, Moderate, Severe Dementia (when severity is unspecified): Although F03.90 specifies “unspecified severity,” these terms are related as they describe different stages of dementia that might fall under the unspecified category if not clearly documented.
- Dementia without behavioral disturbance: This directly aligns with part of the F03.90 description, highlighting cases where behavioral symptoms are absent.
Clinically, dementia, as described in the provided information, is:
- An acquired organic mental disorder characterized by a loss of intellectual abilities that is severe enough to interfere with social or occupational functioning.
- A condition impacting various cognitive domains including memory, behavior, personality, judgment, attention, spatial relations, language, abstract thought, and executive functions.
- Typically progressive in nature, with an initial preservation of consciousness level.
Dementia is not a normal part of aging but a result of brain disorders or diseases. It’s crucial to differentiate between age-related memory changes and the significant cognitive decline seen in dementia.
Code History and Reimbursement
ICD-10-CM code F03.90 has been in use since 2016, with revisions to its description in 2023 to further clarify the absence of behavioral, psychotic, mood, and anxiety disturbances. The existence of a specific and billable code like F03.90 is vital for:
- Accurate claims processing and healthcare reimbursement. Using the correct ICD-10 code ensures that healthcare providers are appropriately reimbursed for the diagnosis and management of patients with unspecified dementia.
- Public health statistics and epidemiology. Tracking the use of F03.90 and related dementia codes allows for monitoring the prevalence and patterns of dementia on a population level.
- Clinical documentation and communication. Standardized coding facilitates clear communication among healthcare professionals regarding patient diagnoses.
Conclusion
ICD-10-CM code F03.90, Unspecified dementia, unspecified severity, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety, is a critical code in the landscape of dementia diagnosis. It serves to classify cases where dementia is diagnosed but the specific type and severity are not determined, and importantly, where significant behavioral and psychological symptoms are absent. Understanding the nuances of F03.90 is essential for accurate medical coding, billing, and for contributing to a clearer picture of dementia within healthcare systems. For comprehensive dementia diagnosis and management, further investigation to specify the type and severity of dementia, as well as the presence or absence of neuropsychiatric symptoms, is always recommended when possible to move beyond an “unspecified” classification.
