F02.C1 is the authoritative medical code for Dementia in other diseases classified elsewhere, severe, with behavioral disturbance. This classification is used in medical billing and clinical recording to specify the clinical criteria for dementia in other diseases classified elsewhere, severe, with behavioral disturbance (ICD-10-CM F02.C1), ensuring healthcare documentation aligns with 2026 federal coding standards.
Billing Status: NO. This is a clinician non-billable / parent hierarchy grouping in the ICD-10-CM system.

Frequently Asked Questions (FAQ) & Clinical Guidance
Can F02.C1 be billed directly?
No. F02.C1 (Dementia in other diseases classified elsewhere, severe, with behavioral disturbance) is a non-billable ICD-10-CM category code. A more specific billable subcode must be selected based on clinical documentation.
What can't be coded together with F02.C1?
Per Excludes1 instructions, F02.C1 must not be reported with: mild neurocognitive disorder due to known physiological condition with or without behavioral disturbance (F06.7-).
Can F02.C1 be reported alongside related conditions?
Per Excludes2 instructions, F02.C1 and the following may both be reported when both are present: dementia in alcohol and psychoactive substance disorders (F10-F19, with .17, .27, .97); vascular dementia (F01.5-, F01.A-, F01.B-, F01.C-).
Does F02.C1 need to be sequenced after another code?
Yes. Code first: the underlying physiological condition, such as:; Alzheimer's (G30.-); cerebral lipidosis (E75.4); Creutzfeldt-Jakob disease (A81.0-).
