Additional Info

• This refers to states of cerebral dysfunction associated with a disturbance in any of consciousness, cognition, mood, affect, and behavior in the absence of drugs, infection, or a metabolic cause. These usually are due to fixed, anatomic abnormalities, though these do not always show up on brain imaging.
  • Thus, the "nonorganic" types are those due to drugs/substances, infection or metabolic causes, i.e. that they are (at least in principle) reversible.

Altered mental status coding guideline

Coding altered mental status in ICD10 can be complex, see ICD10 Guideline for coding altered mental status for more info.

Alternate ICD10s to consider coding instead or in addition

• Organic amnestic syndrome, not due to drugs or alcohol
• Encephalitis, meningoencephalitis, myelitis, encephalomyelitis, noninfectious
• Encephalitis, meningoencephalitis, myelitis, encephalomyelitis, infectious NOS
• Psychoactive substance NOS, acute intoxication
• Alcohol, chronic abuse/dependence/addiction
• Delirium, not due to drugs or alcohol
• Dementia, NOS
