E-collection 'Anxiety and Stress Disorders'

The following are some common forms of anxiety with their associated ICD-9-CM code: • Generalized anxiety disorder (300.02) — involves six months of persistent, excessive, and unrealistic worry. • Panic disorder (300.01) — may have a sudden onset causing apprehension, fear, or terror. Physical symptoms may include shortness of breath, heart palpitations, or chest pain, causing a person to think he or she is having a heart attack. If the panic attack is associated with agoraphobia (fear of places or situations where someone feels trapped or helpless), assign code 300.21. • Obsessive-compulsive disorder (300.3) — involves persistent, recurring thoughts/impulses (obsessions) and ritualistic actions (compulsions). This is different than obsessive-compulsive personality disorder (301.4). • Posttraumatic stress disorder (309.81) — occurs after a severe emotional or physical trauma and involves the feeling that the person is reexperiencing this traumatic event. • Acute stress disorder (308.3) — includes similar symptoms to posttraumatic stress disorder but occurs immediately after a traumatic event. • Social phobia (300.23) — a person may experience anxiety when exposed to certain social events and desires to avoid the situation. • Other phobia (300.2x) — anxiety when exposed to a specific object or situation and the desire to avoid it. • Alcohol-induced anxiety (291.89) • Drug-induced anxiety (292.89) • Separation anxiety (309.21) — occurs when a child is separated from his or her parents.
