ICD-10 Code F03.93 – Unspecified dementia, unspecified severity, with mood disturbance (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F03.93 – Unspecified dementia, unspecified severity, with mood disturbance
What it is
This code identifies dementia when the type and severity are not specified, but mood disturbance is documented. Use it when the record confirms dementia and a mood-related behavioral change, without naming a more specific dementia diagnosis.
Clinical signs
Common findings include cognitive decline with impaired memory, thinking, or daily function, plus mood symptoms such as depression, anxiety, or emotional lability. Clinical features vary; refer to documentation.
When to use this code
Use F03.93 when the provider documents unspecified dementia and separately notes mood disturbance. This may apply in outpatient, inpatient, or long-term care records when the dementia subtype is not clarified. If the note identifies a specific dementia, code that condition instead.
Do not use for
Do not use this code for delirium, mild cognitive impairment, or mood disorders without dementia. Do not assign it when the documentation specifies another dementia type or severity. Check documentation.
Coding tip
Query for the dementia type and severity if the record only says “dementia with mood changes.”
