Name of the Condition

• Anxiety Disorder Due to Known Physiological Condition (ICD-10 Code: F06.4)
• Also known as secondary anxiety disorder or organic anxiety syndrome.

Summary

• Anxiety disorder due to a known physiological condition involves anxiety that is directly linked to a specific physical health issue. This form of anxiety arises as a result of another medical condition affecting the brain or body.

Causes

• This condition occurs due to the presence of a known physiological issue such as endocrine disorders (e.g., hyperthyroidism), cardiovascular conditions, neurological disorders (e.g., Parkinson's disease, epilepsy), or the effects of substances or medications.

Risk Factors

• Possible risk factors include having a chronic illness, age-related health changes, genetic predispositions, and the presence of a neurological or systemic medical condition.

Symptoms

• Symptoms can include excessive fear or worry, physical symptoms like palpitations or tremors, difficulty concentrating, restlessness, irritability, muscle tension, and sleep disturbances.

Diagnosis

• Diagnosis typically involves a comprehensive medical evaluation to identify any underlying physiological conditions. This may include blood tests, medical imaging, a thorough physical examination, and a detailed medical history review.

Treatment Options

• Treatment involves managing the underlying physiological condition, alongside targeted anxiety treatments such as cognitive-behavioral therapy (CBT) or medication like selective serotonin reuptake inhibitors (SSRIs), if needed. Addressing the root physiological cause often alleviates the associated anxiety.

Prognosis and Follow-Up

• Prognosis depends on the underlying condition's nature and treatment effectiveness. Regular follow-up is crucial for monitoring the anxiety and the primary physiological condition to adapt the treatment plan as necessary.

Complications

• Without proper management, this condition can lead to severe anxiety, impacting daily functioning and quality of life. It may also complicate the management of the underlying medical condition.

Lifestyle & Prevention

• Lifestyle interventions include stress management techniques such as mindfulness or yoga, adequate sleep, regular physical activity, and maintaining a balanced diet. Monitoring and managing the primary physiological condition can prevent anxiety disorders from developing.

When to Seek Professional Help

• Immediate professional help should be sought if there is severe anxiety impacting daily activities, any new or worsening physiological symptoms, or if there are thoughts of self-harm.

Tips for Medical Coders

• Ensure precise documentation of the underlying physiological condition and its direct connection to anxiety.
• Cross-reference with other ICD codes linked to the primary physiological condition.
• Avoid coding errors by distinguishing between primary anxiety disorders and those secondary to physiological conditions.
