F20.0 is a billable ICD-10 code used to specify a medical diagnosis of paranoid 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 paranoid schizophrenia
- Acute exacerbation of chronic schizophrenia
- Acute exacerbation of subchronic paranoid schizophrenia
- Chronic paranoid schizophrenia
- Paranoid schizophrenia
- Paranoid schizophrenia in remission
- Schizophrenia in remission
- Subchronic paranoid 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.
Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to this diagnosis code:
Inclusion TermsInclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- Paraphrenic schizophrenia
Type 1 ExcludesType 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
Index to Diseases and Injuries References
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for this diagnosis code are found in the injuries and diseases index:

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.
