ICD-10 Code for Dementia
Also indexed as (degenerative (primary)) (persisting) (unspecified severity) (without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety)
The ICD-10-CM code for dementia is F03.90 — Unspecified dementia, unspecified severity, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety. This is the code the Alphabetic Index gives for dementia with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
BillableUnspecified
F03.90 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
Which dementia code should you use?
The Alphabetic Index lists 104 codes under Dementia. Which one applies depends on the qualifier documented in the record — the type, site, cause, or associated condition. Find the qualifier below, then verify the code in the Tabular List before using it.
