Code Description

ICD-10 F45.29 is a billable code used to indicate a diagnosis of other hypochondriacal disorders.

Key Diagnostic Point:

F45.29 refers to other hypochondriacal disorders characterized by excessive preoccupation with having a serious illness despite medical evaluation and reassurance. Patients may exhibit anxiety symptoms, obsessive thoughts about health, and compulsive behaviors related to health concerns. This condition can overlap with anxiety disorders, PTSD, OCD, and specific phobias, complicating diagnosis and treatment. Individuals may frequently seek medical attention, undergo unnecessary tests, or avoid situations they believe could harm their health. Effective management often requires a multidisciplinary approach, including psychotherapy, cognitive-behavioral therapy (CBT), and sometimes pharmacotherapy. Understanding the interplay between hypochondriacal disorders and other anxiety-related conditions is crucial for accurate diagnosis and treatment planning.
