Is F06 a billable ICD-10-CM code?

No. F06 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does F06 sit in the tabular list?

Mental, Behavioral and Neurodevelopmental disorders (F01-F99), in the block Mental disorders due to known physiological conditions (F01-F09).

What cannot be coded together with F06?

F06 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

F06 — Other mental disorders due to known physiological condition

Non-billable headerICD-10-CM

F06 is a non-billable header ICD-10-CM code for other mental disorders due to known physiological condition. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

unspecified dementia (F03.-)

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

delirium due to known physiological condition (F05)
dementia as classified in F01-F02
other mental disorders associated with alcohol and other psychoactive substances (F10-F19)

Code first

The underlying condition must be sequenced before this code.

the underlying physiological condition

Includes

Conditions this code covers.

mental disorders due to endocrine disorder
mental disorders due to exogenous hormone
mental disorders due to exogenous toxic substance
mental disorders due to primary cerebral disease
mental disorders due to somatic illness
mental disorders due to systemic disease affecting the brain

Other codes that can never be billed with F06

These codes carry an Excludes1 note pointing at F06. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading F06 alone.

R41.3Other amnesia
F01.AVascular dementia, mild
F02Dementia in other diseases classified elsewhere
F02.ADementia in other diseases classified elsewhere, mild
F03.AUnspecified dementia, mild
F09Unspecified mental disorder due to known physiological condition
G31.84Mild cognitive impairment of uncertain or unknown etiology

Risk adjustment

F06 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead F06

7 child codes. Green means billable.
