F02.81 — Dementia in other diseases classified elsewhere, unspecified severity, with behavioral disturbance
Is F02.81 billable?
No — F02.81 is a non-billable header code. F02.81 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 2 billable codes beneath F02.81.

How is F02.81 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to F02.81. They show the wording a clinician may have documented, which often differs from the Tabular description.
- Aphasia › primary progressive › with behavioral disturbance (amnestic) (global) (nominal) (semantic) (syntactic)
- Aphasia › progressive isolated › with behavioral disturbance (amnestic) (global) (nominal) (semantic) (syntactic)
- Atrophy, atrophic › sclerosis, lobar › with behavioral disturbance (of)
- Dementia › frontal › with behavioral disturbance (degenerative (primary)) (persisting) (unspecified severity) (without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety)
- Dementia › frontotemporal › with behavioral disturbance (degenerative (primary)) (persisting) (unspecified severity) (without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety)
- Dementia › Lewy body › with behavioral disturbance (degenerative (primary)) (persisting) (unspecified severity) (without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety)
- Dementia › paralytica, paralytic › with behavioral disturbance (degenerative (primary)) (persisting) (unspecified severity) (without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety)
- Disease, diseased › Alzheimer's › with behavioral disturbance
- Disease, diseased › Lewy body › with behavioral disturbance
- Disease, diseased › Pick's › with behavioral disturbance
- Huntington's disease or chorea › with dementia › with behavioral disturbance
- Parkinsonism › dementia › with behavioral disturbance (idiopathic) (primary)
Excludes1 — never code together — inherited from F02
The conditions below can never be reported together with F02.81 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 F02.81. F02.81 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 — inherited from Chapter 5
The conditions below are not part of F02.81, but a patient may have both at the same time. When documentation supports it, F02.81 and the excluded code may both be reported.
- symptoms, signs and abnormal clinical laboratory findings, not elsewhere classified (R00-R99)
Excludes2 — not included here — inherited from F02
The conditions below are not part of F02.81, but a patient may have both at the same time. When documentation supports it, F02.81 and the excluded code may both be reported.
What codes fall under F02.81? (2)
How long has F02.81 existed?
F02.81 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
- FY2023: F02.81 stopped being billable
- FY2023Dementia in other diseases classified elsewhere with behavioral disturbanceDementia in other diseases classified elsewhere, unspecified severity, with behavioral disturbance
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
