Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the F40 range.
Agoraphobia
Obsessive, persistent, intense fear of places or situations from which escape might be difficult or embarrassing.
Claustrophobia
Persistent and irrational fear of enclosed places (e.g., elevators, closets, tunnels) or of being confined (e.g., in an airplane or the backseat of a car). Situations where enclosure or confinement may be encountered are often avoided or else endured with intense anxiety or distress. The focus of fear is typically on panic symptoms triggered in these situations, such as feelings of being unable to breathe, choking, sweating, and fears of losing control. (From APA Dictionary of Psychology, accessed 11/8/2023)
Phobia, Social
Anxiety disorder characterized by the persistent and irrational fear, anxiety, or avoidance of social or performance situations.
Phobic Disorders
Anxiety disorders in which the essential feature is persistent and irrational fear of a specific object, activity, or situation that the individual feels compelled to avoid.
About the F40 Code Range
Phobic anxiety disorders include agoraphobia, social phobias, and specific fears involving animals, natural environments, medical care, or situations.
F40.0 separates agoraphobia by whether panic disorder is present. F40.1 distinguishes generalized social phobia from unspecified social phobia. F40.2 groups specific phobias by type, then names fears such as thunderstorms, blood, and flying. F40.8 and F40.9 identify other and unspecified phobic anxiety disorders.
