F42 – Obsessive-compulsive disorder

F42 diagnosis code: Obsessive-compulsive disorder

F42 diagnosis corresponds to obsessive-compulsive disorder (OCD), a chronic mental health condition characterized by intrusive, distressing thoughts (obsessions) and repetitive behaviors (compulsions) aimed at alleviating anxiety. Individuals with OCD often experience significant impairment in daily functioning and struggle to control intrusive thoughts and ritualistic behaviors.

When coding, it is worth noting that type 2 excludes related conditions: obsessive-compulsive personality disorder (F60.5), obsessive-compulsive symptoms occurring in depression (F32–F33), and obsessive-compulsive symptoms occurring in schizophrenia (F20.-).

Is F42 billable?

The ICD-10 CM states that F42 is not recommended for reimbursement purposes because multiple codes under it offer more specific details.

Clinical information

• Obsessive-compulsive disorder (OCD) is a psychiatric condition characterized by recurring, intrusive thoughts (obsessions) and repetitive behaviors (compulsions).
• OCD affects people of all ages and backgrounds, and its exact causes are not fully understood. However, it is believed to result from genetic, neurological, and environmental factors. OCD can significantly impact relationships, work, and overall quality of life if left untreated.
• Common obsessions include fear of contamination, doubts about safety, aggressive or taboo thoughts, and the need for symmetry or exactness.
• Compulsions are repetitive actions or mental rituals to reduce anxiety or prevent a feared event. Examples include excessive cleaning, checking, counting, and arranging objects. When a person fails to perform these, they tend to become more stressed or anxious.
• Diagnosis of OCD is based on a comprehensive evaluation of symptoms, their duration, and impairment in functioning.
• Early diagnosis and intervention are crucial for managing OCD symptoms effectively. If an individual experiences persistent obsessions or compulsions, seeking professional help from a mental health specialist is essential. With the proper support and treatment, individuals with OCD can lead fulfilling lives and regain control over their thoughts and behaviors.
• Treatment options for OCD include cognitive-behavioral therapy (CBT), exposure and response prevention (ERP), and medication (such as selective serotonin reuptake inhibitors - SSRIs). CBT helps individuals challenge and change irrational thoughts and develop healthier coping strategies, while ERP involves gradually exposing patients to anxiety-provoking situations while refraining from performing compulsive behaviors.
