Code Description

ICD-10 B05.0 is a billable code used to indicate a diagnosis of measles with pneumonia.

Key Diagnostic Point:

Measles, also known as rubeola, is a highly contagious viral infection characterized by a prodromal phase of fever, cough, coryza, and conjunctivitis, followed by a characteristic rash. When measles is complicated by pneumonia, it can lead to significant morbidity and mortality, especially in young children and immunocompromised individuals. Pneumonia associated with measles can be viral or secondary bacterial infections, often manifesting as a severe respiratory illness. The pathophysiology involves the measles virus impairing the immune response, leading to increased susceptibility to secondary infections. Diagnosis is typically confirmed through clinical presentation and serological testing for measles-specific IgM antibodies. Vaccination with the measles, mumps, and rubella (MMR) vaccine is crucial for prevention, and it is recommended that children receive their first dose at 12-15 months of age, with a second dose at 4-6 years. Complications from measles, including pneumonia, can be severe, necessitating prompt medical attention and appropriate coding to reflect the complexity of the patient's condition.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between viral and bacterial pneumonia
  • Need for accurate documentation of complications
  • Potential for co-infections requiring additional codes
  • Variability in clinical presentation among different age groups

Audit Risk Factors

  • Inadequate documentation of pneumonia severity
  • Failure to specify the type of pneumonia (viral vs. bacterial)
  • Lack of supporting lab results for measles diagnosis
  • Misclassification of measles complications

Frequently Asked Questions

What are the common complications associated with measles?

Common complications include pneumonia, encephalitis, and otitis media. Pneumonia is the most serious complication and can be caused by the measles virus itself or secondary bacterial infections.
