ICD-10 code for schizoid personality disorder

Living with schizoid personality disorder (ScPD) means experiencing the world through a uniquely detached lens. Those with this condition often find themselves preferring solitude, showing limited emotional expression, and feeling little desire for close relationships. While this pattern of social detachment can create significant challenges in work and personal life, many individuals with ScPD can build meaningful lives while honoring their need for independence.

The ICD-10 code for schizoid personality disorder is F60.1. This code appears under the broader category of specific personality disorders (F60) alongside other Cluster A personality disorders like paranoid personality disorder (F60.0) and schizotypal disorder (F21).

Schizoid personality disorder is estimated to occur in less than 1% of the general population, with longitudinal studies finding its characteristics to remain quite stable into adulthood. According to the DSM-5, diagnostic criteria, schizoid personality disorder manifests as a pervasive pattern of detachment from social relationships and limited expression of emotions in interpersonal settings. The core features include neither desiring nor enjoying close relationships, almost always choosing solitary activities, having little interest in sexual experiences with others, taking pleasure in few activities, lacking close confidants other than immediate family, appearing indifferent to praise or criticism, and showing emotional coldness or flattened affect.

When to use F60.1 for schizoid personality disorder

Clinicians should use code F60.1 when a patient demonstrates a persistent pattern of social detachment and restricted emotional expression that begins by early adulthood and presents across multiple contexts. However, careful differential diagnosis is essential, as similar symptoms may appear in autism spectrum disorders, major depressive disorder, and other personality disorders. For accurate diagnosis and coding, the symptoms should not occur exclusively during episodes of schizophrenia or other psychotic disorders.

Schizoid personality disorder vs. schizotypal personality disorder 

ScPD and schizotypal personality disorder share some genetic and environmental risk factors, but maintain distinct clinical presentations. While both conditions involve social difficulties, schizoid personality disorder (F60.1) is characterized primarily by detachment and limited emotional expression, whereas schizotypal personality disorder (F21) includes additional features like magical thinking, unusual perceptual experiences, and paranoid ideation. Individuals with ScPD typically maintain reality testing and do not experience the cognitive-perceptual distortions seen in schizotypal disorder.

Schizoid personality disorder vs. avoidant personality disorder

Although both disorders may lead to social isolation, individuals with avoidant personality disorder (F60.6) actively desire relationships but avoid them due to fears of rejection and criticism. In contrast, those with ScPD have limited interest in social relationships and feel no distress about their solitary lifestyle.
