Whooping cough due to Bordetella pertussis

Code Description

ICD-10 A37.0 is a billable code used to indicate a diagnosis of whooping cough due to bordetella pertussis.

Key Diagnostic Point:

Whooping cough, also known as pertussis, is a highly contagious respiratory disease caused by the bacterium Bordetella pertussis. It is characterized by severe coughing fits that can lead to a 'whooping' sound during inhalation. The disease primarily affects infants and young children but can also occur in adolescents and adults. The clinical presentation typically begins with mild respiratory symptoms, including a runny nose, sneezing, and low-grade fever, which can progress to paroxysmal coughing episodes. These coughing fits can be so severe that they lead to vomiting or difficulty breathing. Complications may include pneumonia, seizures, and in rare cases, death, particularly in infants. Vaccination with the DTaP (diphtheria, tetanus, and pertussis) vaccine is the primary preventive measure against whooping cough. Treatment usually involves antibiotics, such as azithromycin or erythromycin, which are most effective when administered early in the course of the disease. However, antibiotic resistance patterns have been observed, necessitating careful selection of treatment regimens. Public health measures, including vaccination campaigns and monitoring of outbreaks, are crucial in controlling the spread of this disease.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between whooping cough and other respiratory infections
  • Understanding the timing of symptoms for accurate coding
  • Recognizing the importance of vaccination history in coding
  • Identifying complications that may require additional codes

Audit Risk Factors

  • Inadequate documentation of symptoms and their duration
  • Failure to document vaccination status
  • Misidentification of the causative organism
  • Omission of complications that may require additional coding
