Code Description

ICD-10 R09.01 is a billable code used to indicate a diagnosis of asphyxia.

Key Diagnostic Point:

Asphyxia is a condition characterized by a deficiency of oxygen in the body, leading to a state of hypoxia and potentially resulting in unconsciousness or death if not promptly addressed. It can manifest through various symptoms including cyanosis (bluish discoloration of the skin), altered mental status, tachycardia, and respiratory distress. Clinical findings may include abnormal arterial blood gas levels, such as decreased oxygen saturation and elevated carbon dioxide levels. Asphyxia can arise from multiple causes, including airway obstruction (due to choking or foreign body aspiration), drowning, suffocation, or exposure to toxic gases. The clinical context often involves acute presentations requiring immediate intervention, and the diagnosis is typically supported by clinical evaluation and laboratory tests that assess oxygenation and ventilation status. Understanding the underlying cause is crucial for effective management and prevention of recurrence.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of potential underlying causes
  • Need for precise documentation of clinical findings
  • Differentiation from similar respiratory conditions
  • Potential for misdiagnosis in acute settings

Audit Risk Factors

  • Inadequate documentation of clinical findings
  • Failure to specify the cause of asphyxia
  • Misuse of related codes leading to upcoding or downcoding
  • Lack of clarity in the patient's clinical status
