ICD-10 codes for Dementia
Dementia is coded primarily under F03, F03.90, F01 in the ICD-10-CM (Clinical Modification) classification. Top-level categories include F01 (Vascular dementia); F02 (Dementia in other diseases classified elsewhere); F03 (Unspecified dementia); G30 (Alzheimer's disease). The 2025 ICD-10-CM code set includes 120 codes related to dementia, of which 89 are billable (specific enough to appear on a medical claim).
Dementia codes in ICD-10-CM live under F01 (vascular dementia), F02 (dementia in other diseases classified elsewhere, used with the underlying disease code), and F03 (unspecified dementia). G31.83 covers dementia with Lewy bodies, and G30 is reserved for Alzheimer disease (also coded with F02).

What is the ICD-10 code for dementia?
The primary ICD-10-CM codes for dementia are F03, F03.90, F01. Across all sub-categories, 120 codes are grouped under dementia, with 89 marked as billable (specific enough for a medical claim).
How many ICD-10 codes are there for dementia?
There are 120 ICD-10-CM codes related to dementia. Of these, 89 are billable specific codes and 31 are non-billable header categories that organize the specific codes underneath them. Header codes cannot be reported on a claim by themselves.
Is there a billable ICD-10 code for dementia?
Yes. 89 of the 120 ICD-10-CM codes for dementia are billable. Common examples include F01.50 (Vascular dementia, unsp severity, without beh/psych/mood/anx); F01.511 (Vascular dementia, unspecified severity, with agitation); F01.518 (Vascular dementia, unsp severity, with other beh disturb). Code to the highest level of specificity supported by the documentation.
Which dementia ICD-10 code should I use for billing?
The most commonly used billable codes for dementia include: F01.50 (Vascular dementia, unsp severity, without beh/psych/mood/anx); F01.511 (Vascular dementia, unspecified severity, with agitation); F01.518 (Vascular dementia, unsp severity, with other beh disturb). The correct code depends on the documented clinical presentation, including any complications, episode (acute / chronic), and laterality where applicable. Always code to the highest level of specificity supported by the clinical documentation.
Is F03 a billable ICD-10 code?
No, F03 (Unspecified dementia) is a non-billable header code. You need to use a more specific child code for billing purposes.
What are the SNOMED CT concepts for dementia?
The ICD-10 codes for dementia map to at least 25 SNOMED CT concepts. Examples of SNOMED CT concept IDs in this group include 106021000119105, 1259485008, 1259488005, 14070001, 16276361000119109. SNOMED CT is a clinical terminology used in electronic health records; AutoICD's coding API returns SNOMED CT IDs alongside each ICD-10 code via the include_snomed=true flag.
What UMLS Concept Unique Identifiers (CUIs) cover dementia?
The ICD-10 codes for dementia are linked to at least 25 UMLS CUIs in the National Library of Medicine's Metathesaurus. Sample CUIs include C0011263, C0011269, C0600359, C5676338, C5674898. UMLS CUIs unify the same concept across SNOMED CT, ICD-10, ICD-11, RxNorm, MeSH, and dozens of other source vocabularies.
What are other names for dementia in ICD-10?
Dementia may also be referred to as: dementia, vascular dementia, Lewy body dementia, frontotemporal dementia, senile dementia. The same ICD-10-CM codes apply regardless of which term appears in the clinical documentation. Synonyms are surfaced by AutoICD's NER pass and mapped to the canonical ICD-10 family above.
