Is F02 a billable ICD-10-CM code?

No. F02 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does F02 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 F02?

F02 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

F02

F02 — Dementia in other diseases classified elsewhere

Non-billable headerICD-10-CM

F02 is a non-billable header ICD-10-CM code for dementia in other diseases classified elsewhere. 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.

mild neurocognitive disorder due to known physiological condition with or without behavioral disturbance (F06.7-)

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.

dementia in alcohol and psychoactive substance disorders (F10-F19, with .17, .27, .97)
vascular dementia (F01.5-, F01.A-, F01.B-, F01.C-)

Code first

The underlying condition must be sequenced before this code.

the underlying physiological condition, such as:
Alzheimer's (G30.-)
cerebral lipidosis (E75.4)
Creutzfeldt-Jakob disease (A81.0-)
epilepsy and recurrent seizures (G40.-)
frontotemporal dementia (G31.09)
hepatolenticular degeneration (E83.01)
human immunodeficiency virus [HIV] disease (B20)
Huntington's disease (G10)
hypercalcemia (E83.52)
hypothyroidism, acquired (E00-E03.-)
intoxications (T36-T65)
Jakob-Creutzfeldt disease (A81.0-)
multiple sclerosis (G35-)
neurocognitive disorder with Lewy bodies (G31.83)
neurosyphilis (A52.17)
niacin deficiency [pellagra] (E52)
other frontotemporal neurocognitive disorder (G31.90)
Parkinson's disease (G20.-)
Pick's disease (G31.01)
polyarteritis nodosa (M30.0)
prion disease (A81.9)
systemic lupus erythematosus (M32.-)
traumatic brain injury (S06.-)
trypanosomiasis (B56.-, B57.-)
vitamin B deficiency (E53.8)

Includes

Conditions this code covers.

Major neurocognitive disorder in other diseases classified elsewhere

Other codes that can never be billed with F02

These codes carry an Excludes1 note pointing at F02. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading F02 alone.

F06.7Mild neurocognitive disorder due to known physiological condition
G31.84Mild cognitive impairment of uncertain or unknown etiology

Risk adjustment

F02 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 F02

4 child codes. Green means billable.
