Mental disorders due to known physiological conditions (F01-F09)

ICD-10 codes F01-F09 cover mental disorders caused by identifiable physical conditions affecting the brain. These codes are primarily used to classify various forms of dementia, delirium, amnestic disorders, mood and psychotic disorders, and personality changes linked directly to physiological causes.

This range includes detailed codes for vascular dementia (F01), differentiating severity levels and associated behavioral or psychotic symptoms. The extensive list of synonyms, such as "multi-infarct dementia" and "arteriosclerotic dementia," helps clinicians and coders assign precise diagnoses. Codes F02 specify dementia occurring with other medical diseases, including conditions like Parkinson’s disease, Alzheimer’s disease, and metabolic deficiencies, capturing various severities and behavioral disturbances. F03 is reserved for unspecified dementia types with varying symptom severity.

Delirium due to known physiological conditions is categorized under F05, covering acute confusional states with a range of causes like infections or surgery. The F06 codes address psychotic and mood disorders stemming from physical health issues, including hallucinations, delusions, and organic mood disorders such as bipolar or depressive states. Personality and behavioral disorders resulting from brain damage fall under F07, with postconcussional syndrome included. Lastly, F09 is used for mental disorders due to known physiological conditions that are unspecified, capturing cases where clear classification is difficult. Together, these codes guide accurate diagnosis and treatment documentation for cognitive and psychiatric conditions linked to physical brain pathology.

Instructional Notations

  • This block comprises a range of mental disorders grouped together on the basis of their having in common a demonstrable etiology in cerebral disease, brain injury, or other insult leading to cerebral dysfunction. The dysfunction may be primary, as in diseases, injuries, and insults that affect the brain directly and selectively; or secondary, as in systemic diseases and disorders that attack the brain only as one of the multiple organs or systems of the body that are involved.
