Code Description

ICD-10 R06.4 is a billable code used to indicate a diagnosis of hyperventilation.

Key Diagnostic Point:

Hyperventilation is characterized by an increased rate and/or depth of breathing, leading to a decrease in carbon dioxide levels in the blood (hypocapnia). This condition can manifest as a result of various physiological and psychological factors, including anxiety, panic attacks, respiratory disorders, or metabolic conditions. Clinically, patients may present with symptoms such as lightheadedness, palpitations, chest pain, tingling in the extremities, and shortness of breath. Abnormal clinical findings may include respiratory alkalosis on arterial blood gas analysis, where pH levels are elevated, and carbon dioxide levels are decreased. It is essential to differentiate hyperventilation from other respiratory conditions, as its management may vary significantly based on the underlying cause. Understanding the context of hyperventilation is crucial for accurate diagnosis and treatment, as it can be a primary condition or a symptom of an underlying disorder.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of underlying causes (e.g., anxiety, metabolic disorders)
  • Potential overlap with other respiratory conditions
  • Need for thorough documentation of symptoms and triggers
  • Variability in clinical presentation among patients

Audit Risk Factors

  • Inadequate documentation of the underlying cause
  • Failure to specify if hyperventilation is acute or chronic
  • Misdiagnosis due to overlapping symptoms with other conditions
  • Lack of supporting clinical findings in the medical record
