Basic Criteria for Schizophrenia

After at least 1 year as passed since onset, classify the course of psychosis. Until a year has passed, you cannot assign any of these course specifiers.***

Continuous. There has been no remission of "A" symptoms (first bullet). If negative symptoms stand out, you can also add "With Prominent Negative Symptoms."

Episodic With Interepisode Residual Symptoms. During episodes, "A" criteria are met. Between episodes the patient has clinically important residual symptoms. If negative symptoms stand out, you can also add "With Prominent Negative Symptoms."

Episodic With No Interepisode Residual Symptoms. During episodes, "A" criteria are met. Between episodes the patient has remissions with no clinically important symptoms.

Single Episode in Partial Remission. There has been one episode during which "A" criteria are met. Now there are some clinically important residual symptoms. If negative symptoms stand out, you can also add "With Prominent Negative Symptoms."

Single Episode in Full Remission. No clinically important symptoms remain.

Other or Unspecified Pattern.

 

Coding Notes

*DSM-IV refers collectively to these five symptoms as the "A" criteria.

**If the illness begins in childhood or adolescence, the criteria for dysfunction require only that the patient fail to achieve the expected occupational, scholastic or social level.

***These longitudinal specifiers are listed last, following the term Schizophrenia and the subtype diagnosis (paranoid, disorganized, catatonic, undifferentiated, residual).

 


Paranoid type

 


Disorganized type

 


Catatonic Type

 

Coding Notes

Negativism is demonstrated when the patient (1) refuses to follow all instructions without apparent motive or (2) maintains a rigid posture despite the examiner's physical attempts.

Mannerisms are unnecessary movements that are part of goal-directed behavior, such as a flourish of the pen when signing a document).

Stereotypies are behaviors that do not appear to be goal-directed, such as flashing a "Victory" sign with two upraised fingers every few seconds.

Posturing means that the patient spontaneously poses or assumes a posture that is bizarre or inappropriate.

 


Undifferentiated Type

 


Residual Type

 


Schizophreniform Disorder

A statement of prognosis should be added to the diagnosis:

Without Good Prognostic Features (zero or 1 of the foregoing)

 

Coding Notes

If the diagnosis is made without waiting for recovery, which will often be the case, the term "(Provisional)" should be appended.

 


Schizoaffective Disorder

Specify whether:

Bipolar Type. The episode is either Manic, Mixed or Major Depressive with either Manic or Mixed.

Depressive Type. The episode is only Major Depressive.

 

Coding Notes

*These are the "A" criteria for schizophrenia.

 


Delusional Disorder

Specify type, as listed in first bullet above.

 


Brief Psychotic Disorder

Specify whether:

With Postpartum Onset. In a woman, the disorder begins within 4 weeks of having a baby.

With Marked Stressor(s). The stressors must appear to cause the symptoms, occur shortly before their onset and be severe enough that nearly anyone of that culture would feel markedly stressed.

Without marked stressor(s).

 

Coding Notes

If the diagnosis is made without waiting for recovery, the term "Provisional" should be appended.

 


Shared Psychotic Disorder

 


Psychotic Disorder Due to a General Medical Condition

Code, based on the predominant symptoms:

.x1 With Delusions

.x2 With Hallucinations

 

Coding notes

Use the name of the medical disorder in the Axis I code, not "General Medical Condition."

On Axis III, also code the specific general medical condition that has caused the psychosis.

If the patient has a preexisting Dementia (Alzheimer's or Vascular) and then becomes psychotic, do not use code 293.8x. Instead, the Cognitive Disorder takes precedence, and you would code, for example, 290.42 Vascular Dementia, with delusions.

 


Substance-Induced Psychotic Disorder

The codes used for Substance-Induced Psychotic Disorder are somewhat arcane. Different numbers are used to describe a psychosis with delusions and with hallucinations, and the coding for alcohol-induced psychoses is different from all other substances. If delusions and hallucinations are both present, code the one that dominates the clinical picture. The numbers to use are:

With Delusions:

291.5 Alcohol

292.11 Amphetamine [or Amphetamine-Like Substance]; Cannabis; Cocaine; Hallucinogen; Inhalant; Opioid; Phencyclidine [or Phencyclidine-Like Substance]; Sedative, Hypnotic or Anxiolytic; Other [or Unknown] Substance

With Hallucinations:

291.3 Alcohol

292.12 Amphetamine [or Amphetamine-Like Substance]; Cannabis; Cocaine; Hallucinogen; Inhalant; Opioid; Phencyclidine [or Phencyclidine-Like Substance]; Sedative, Hypnotic or Anxiolytic; Other [or Unknown] Substance

When criteria are met for substance-specific intoxication or withdrawal (page 57), specify whether:

With Onset During Intoxication.

With Onset During Withdrawal

 

Coding Notes

* DSM-IV suggests several instances in which a disorder other than substance use could better explain the symptoms of psychosis. These include:

-Psychotic symptoms begin before the onset of the substance abuse.

-Psychotic symptoms persist long after (a month or more) the substance abuse stops.

-Psychotic symptoms are more severe than you would expect from the amount and extent of substance abuse.

-The patient has had previous psychotic episodes independent of substance use.

Use this diagnosis instead of Substance Intoxication or Substance Withdrawal only (1) when the symptoms exceed those you would expect from a syndrome of intoxication or withdrawal and (2) when they are serious enough by themselves to require clinical care.

Psychoses caused by most medications taken in therapeutic doses would be coded as, for example:

Axis I 292.11 Estrogen-Induced Psychotic Disorder, With Hallucinations, With Onset During Intoxication

Axis III E932.2 Ovarian hormones

 


298.9 Psychotic Disorder Not Otherwise Specified
