Range Overview
The F20-F29 range in ICD-10 is dedicated to schizophrenia, schizotypal, delusional, and other non-mood psychotic disorders. These codes are used to identify and classify various types of psychotic disorders that are not primarily related to mood, but to altered reality perception. This range includes specific codes for different types of schizophrenia, persistent delusional disorders, acute and transient psychotic disorders, schizoaffective disorders, and other nonorganic psychotic disorders.
Key Usage Points:
- •F20 codes are used for different subtypes of schizophrenia, including paranoid, hebephrenic, and catatonic.
- •F22 codes are used for persistent delusional disorders.
- •F23 codes are for acute and transient psychotic disorders.
- •F25 is used for schizoaffective disorders.
- •F28 and F29 codes are used for other and unspecified nonorganic psychotic disorders.
Coding Guidelines
When to Use:
- ✓When a patient is diagnosed with a specific subtype of schizophrenia.
- ✓When a patient presents with persistent delusions.
- ✓When a patient experiences an acute and transient psychotic episode.
- ✓When a patient is diagnosed with a schizoaffective disorder.
- ✓When a patient presents with a nonorganic psychotic disorder not specified elsewhere.
When NOT to Use:
- ✗When the psychotic symptoms are secondary to a mood disorder.
- ✗When the psychosis is due to substance abuse or withdrawal.
- ✗When the psychosis is a result of a known physical condition.
- ✗When the psychosis is part of a pervasive developmental disorder.
Code Exclusions
Always verify exclusions with the latest ICD-10-CM official guidelines.
Documentation Requirements
Documentation for F20-F29 codes should clearly indicate the specific type of psychotic disorder. It should include details about the nature and duration of symptoms, the impact on the patient's functioning, and any associated conditions.
Clinical Information:
- •Specific type of psychotic disorder
- •Duration and frequency of symptoms
- •Severity of symptoms
- •Impact on patient's functioning
- •Associated conditions or substance use
Supporting Evidence:
- •Clinical examination findings
- •Psychiatric evaluation
- •History from patient and informants
- •Results of any relevant tests or imaging
Good Documentation Example:
Patient diagnosed with paranoid schizophrenia. He experiences frequent auditory hallucinations and has severe social impairment. No substance use reported.
Poor Documentation Example:
Patient has schizophrenia.
Common Documentation Errors:
- ⚠Not specifying the type of psychotic disorder
- ⚠Not documenting the duration and frequency of symptoms
- ⚠Not indicating the impact on the patient's functioning
- ⚠Not documenting any associated conditions or substance use

Coding Complexity
Coding for F20-F29 requires a good understanding of different types of psychotic disorders and their clinical features. It also requires careful review of the documentation to identify all relevant details.
Key Factors:
- ▸Determining the specific type of psychotic disorder
- ▸Distinguishing between acute and persistent disorders
- ▸Identifying any associated conditions or substance use
- ▸Understanding the impact of the disorder on the patient's functioning
Specialty Focus
The F20-F29 codes are primarily used by psychiatrists and other mental health professionals. They may also be used by primary care providers when managing patients with psychotic disorders.
Primary Specialties:
Clinical Scenarios:
- • A patient presenting with auditory hallucinations and delusions of persecution.
- • A patient with a long-standing belief that they are being followed, without any evidence.
- • A patient experiencing an acute psychotic episode following a stressful event.
