F02.8 — Dementia in other diseases classified elsewhere, unspecified severity
Is F02.8 billable?
No — F02.8 is a non-billable header code. F02.8 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 6 billable codes beneath F02.8.

Excludes1 — never code together — inherited from F02
The conditions below can never be reported together with F02.8 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 — inherited from F02
The underlying condition below must be sequenced before F02.8. F02.8 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)

- systemic lupus erythematosus (M32.-)
- traumatic brain injury (S06.-)
- trypanosomiasis (B56.-, B57.-)
- vitamin B deficiency (E53.8)
Excludes2 — not included here — inherited from Chapter 5
The conditions below are not part of F02.8, but a patient may have both at the same time. When documentation supports it, F02.8 and the excluded code may both be reported.
- symptoms, signs and abnormal clinical laboratory findings, not elsewhere classified (R00-R99)
