What does ICD-10-CM code F03.90 mean?
F03.90 represents Unspecified dementia, unspecified severity, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety. This code is classified under Chapter 5 (Mental, Behavioral and Neurodevelopmental Disorders) and is used to document this behavioral health condition for clinical reporting and billing purposes. Coders frequently reference this code as dementia icd 10, dementia icd 10 code, dementia unspecified icd 10, or dementia without behavioral disturbance icd 10.

Guideline notes and coding considerations
Specificity Warning
F03.90 is an unspecified code. Query the provider for greater specificity when documentation suggests a more precise code is available. Using unspecified codes when specific codes exist may trigger audits.
- Specificity: Assign F03.90 only when documentation supports this specific diagnosis.
Learn the underlying rules in the ICD-10 Coding Guidelines, Specificity Requirements, Risk Adjustment & MEAT Documentation.
Documentation tips (what coders should confirm)
- Verify the clinical documentation supports the use of F03.90
- Query the provider for greater specificity if clinical details suggest a more precise code
- This is a risk-adjusted diagnosis — ensure annual documentation with MEAT criteria (Monitor, Evaluate, Assess/Address, Treat)
When NOT to use F03.90
Do not assign F03.90 when the clinical scenario involves: when documentation provides enough detail for a more specific code. Review excludes notes and assign the most specific code supported by documentation.
Audit risk
F03.90 is an unspecified code. Payers and auditors may flag claims with unspecified codes when the medical record contains sufficient detail for a more precise diagnosis. Query the provider for specificity before submitting.

Risk adjustment and HCC mapping
HCC Impact
F03.90 (Unspecified dementia, unspecified severity, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety) maps to the following HCC categories: CMS-HCC V24: HCC 52, CMS-HCC V28: HCC 127, RxHCC V08: HCC 112, ESRD V24: HCC 52. Proper documentation using MEAT criteria (Monitor, Evaluate, Assess/Address, Treat) is required for each encounter to support risk-adjusted diagnoses.

Frequently Asked Questions
The ICD-10-CM code for dementia is F03.90, which represents unspecified dementia, unspecified severity, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety. This code is also commonly referenced as dementia icd 10 code, dementia unspecified icd 10, dementia without behavioral disturbance icd 10. Verify this code using the ICD Code Auditor to ensure guideline compliance.
Yes. F03.90 is an active ICD-10-CM diagnosis code used to classify unspecified dementia, unspecified severity, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety for clinical documentation, reporting, and medical billing purposes.
Use the ICD Code Auditor to check F03.90 against official ICD-10-CM coding guidelines. The tool validates by fiscal year and patient gender to identify potential conflicts.
F03.90 should be used only when clinical documentation does not provide enough detail for a more specific code. Always query the provider when documentation suggests greater specificity is available, as unspecified codes may trigger audits and impact risk adjustment.
Yes. F03.90 maps to HCC 52 in the CMS-HCC V24 model, and HCC 127 in V28. Accurate coding of this condition directly impacts RAF scores for Medicare Advantage plans. Ensure documentation demonstrates the condition was evaluated and managed during the encounter.
Documentation should clearly describe the clinical condition represented by F03.90 (Unspecified dementia, unspecified severity, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety). Include relevant clinical findings, diagnostic test results, provider assessment, and the treatment plan. The diagnosis must be supported by the medical record and not based solely on lab results without clinical interpretation.
