F20.89 is a billable ICD-10 code used to specify a medical diagnosis of other schizophrenia. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Acute exacerbation of chronic schizophrenia
- Cenesthopathic schizophrenia
- Chronic schizophrenia
- Schizophrenia in remission
- Simple schizophrenia
- Subchronic schizophrenia with acute exacerbations
- Schizophrenia-. a severe emotional disorder of psychotic depth characteristically marked by a retreat from reality with delusion formation, hallucinations, emotional disharmony, and regressive behavior.
- Schizophrenia Spectrum and Other Psychotic Disorders-. marked disorders of thought (delusions, hallucinations, or other thought disorder accompanied by disordered affect or behavior), and deterioration from a previous level of functioning. individuals have one o more of the following symptoms: delusions, hallucinations, and disorganized speech. (from dsm-5)
- Schizophrenia, Catatonic-. a type of schizophrenia characterized by abnormality of motor behavior which may involve particular forms of stupor, rigidity, excitement or inappropriate posture.
- Schizophrenia, Childhood-. an obsolete concept, historically used for childhood mental disorders thought to be a form of schizophrenia. it was in earlier versions of dsm but is now included within the broad concept of pervasive development disorders.
- Schizophrenia, Disorganized-. a type of schizophrenia characterized by frequent incoherence; marked loosening of associations, or grossly disorganized behavior and flat or grossly inappropriate affect that does not meet the criteria for the catatonic type; associated features include extreme social withdrawal, grimacing, mannerisms, mirror gazing, inappropriate giggling, and other odd behavior. (dorland, 27th ed)
- Schizophrenia, Paranoid-. a chronic form of schizophrenia characterized primarily by the presence of persecutory or grandiose delusions, often associated with hallucination.
- Schizophrenia, Treatment-Resistant-. a subset of schizophrenia with an inadequate response in target symptoms following treatment with two or more antipsychotics.
- Schizotypal Personality Disorder-. a personality disorder in which there are oddities of thought (magical thinking, paranoid ideation, suspiciousness), perception (illusions, depersonalization), speech (digressive, vague, overelaborate), and behavior (inappropriate affect in social interactions, frequently social isolation) that are not severe enough to characterize schizophrenia.
- Hallucinations-. subjectively experienced sensations in the absence of an appropriate stimulus, but which are regarded by the individual as real. they may be of organic origin or associated with mental disorders.

Schizophrenia is a serious brain illness. People who have it may hear voices that aren't there. They may think other people are trying to hurt them. Sometimes they don't make sense when they talk. The disorder makes it hard for them to keep a job or take care of themselves.
Symptoms of schizophrenia usually start between ages 16 and 30. Men often develop symptoms at a younger age than women. People usually do not get schizophrenia after age 45. There are three types of symptoms:
- Psychotic symptoms distort a person's thinking. These include hallucinations (hearing or seeing things that are not there), delusions (beliefs that are not true), trouble organizing thoughts, and strange movements.
- "Negative" symptoms make it difficult to show emotions and to function normally. A person may seem depressed and withdrawn.
- Cognitive symptoms affect the thought process. These include trouble using information, making decisions, and paying attention.
No one is sure what causes schizophrenia. Your genes, environment, and brain chemistry may play a role.
There is no cure. Medicine can help control many of the symptoms. You may need to try different medicines to see which works best. You should stay on your medicine for as long as your doctor recommends. Additional treatments can help you deal with your illness from day to day. These include therapy, family education, rehabilitation, and skills training.
