Code Description

ICD-10 F45.2 is a billable code used to indicate a diagnosis of hypochondriacal disorders.

Key Diagnostic Point:

Hypochondriacal disorders, classified under ICD-10 code F45.2, are characterized by an excessive preoccupation with having a serious illness. Patients often misinterpret bodily sensations and minor symptoms as indicative of severe medical conditions, leading to significant distress and impairment in daily functioning. This disorder is often associated with anxiety disorders, where individuals may experience heightened anxiety about their health, leading to compulsive behaviors such as frequent doctor visits, excessive health-related research, or avoidance of situations perceived as risky. The condition can co-occur with other mental health disorders, including obsessive-compulsive disorder (OCD), post-traumatic stress disorder (PTSD), and various phobias, complicating the clinical picture. Effective management often requires a multidisciplinary approach, including cognitive-behavioral therapy (CBT) and anxiety management techniques, to help patients reframe their thoughts and reduce health-related anxiety. Understanding the psychological underpinnings of hypochondriacal disorders is crucial for accurate diagnosis and treatment planning.
