F02 — Dementia in other diseases classified elsewhere
Is F02 billable?
No — F02 is a non-billable header code. F02 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 24 billable codes beneath F02.

Excludes1 — never code together
The conditions below can never be reported together with F02 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- mild neurocognitive disorder due to known physiological condition with or without behavioral disturbance (F06.7-)
Code first
The underlying condition below must be sequenced before F02. F02 describes a manifestation and cannot be the principal or first-listed diagnosis.
- the underlying physiological condition, such as:
- Alzheimer's (G30.-)
- cerebral lipidosis (E75.4)
- Creutzfeldt-Jakob disease (A81.0-)
- epilepsy and recurrent seizures (G40.-)
- 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 (G31.09)
- 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)
Excludes2 — not included here
The conditions below are not part of F02, but a patient may have both at the same time. When documentation supports it, F02 and the excluded code may both be reported.
Includes
Conditions classified to F02.
- Major neurocognitive disorder in other diseases classified elsewhere
Excludes2 — not included here — inherited from Chapter 5
The conditions below are not part of F02, but a patient may have both at the same time. When documentation supports it, F02 and the excluded code may both be reported.
- symptoms, signs and abnormal clinical laboratory findings, not elsewhere classified (R00-R99)

How long has F02 existed?
F02 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
