Diagnosis Overview

What is Anxiety With Panic Attacks?
Essential facts and insights about Anxiety with Panic Attacks

Key Clinical Considerations:

  • Recurrent unexpected panic attacks characterized by a sudden surge of intense fear or discomfort that reaches a peak within minutes.
  • At least one of the panic attacks has been followed by a month (or more) of persistent concern about having additional attacks or their consequences.
  • Physical symptoms during panic attacks may include palpitations, sweating, trembling, shortness of breath, feelings of choking, chest pain, nausea, dizziness, chills, or hot flashes.
  • The panic attacks are not attributable to the physiological effects of a substance or another medical condition.
  • The disturbance is not better explained by another mental disorder.

Clinical Information

Clinical Criteria & Documentation Requirements

  • Document the frequency, duration, and intensity of panic attacks.
  • Use specific terminology such as 'panic attack' and 'anxiety disorder' in the medical record.
  • Examples include: 'Patient reports experiencing panic attacks 3 times per week' or 'Symptoms consistent with panic disorder observed during evaluation.'
  • Medical necessity must be established through documentation of the impact on daily functioning.
  • Quality measures may include documentation of treatment response and follow-up care.

Coding Guidelines

Usage Guidelines & Examples

  • Use F41.0 for generalized anxiety disorder without panic attacks; use F41.1 for panic disorder with or without agoraphobia.
  • Do not use this code for anxiety disorders due to a medical condition or substance use.
  • F41.9 (Anxiety disorder, unspecified) may be used when the specific type of anxiety disorder is not determined.
  • Common errors include misclassifying panic attacks as anxiety attacks; ensure accurate terminology is used.
  • In complex cases, consider comorbid conditions and document all relevant diagnoses.

Code Exclusions

Important Exclusions

  • Exclude panic attacks due to substance intoxication or withdrawal.
  • Alternative codes for excluded conditions include F10-F19 for substance-related disorders.
  • Conditions are excluded to ensure accurate diagnosis and treatment planning.
  • Common mistakes include failing to document the context of panic attacks, leading to misdiagnosis.
  • Related but distinct conditions include agoraphobia and specific phobias.
