ICD-10 coding challenge: Legionnaire’s disease
An outbreak of Legionnaire’s disease has plagued residents of the South Bronx area of New York City this summer. At least 12 people have died from the disease and greater than 100 have been sickened by it. The source of the infection has been linked to water cooling towers in the area.
Assign the ICD-10-CM code for Legionella pneumonia. Diagnosis Code
A48.1 Legionnaire’s disease
At the time of this posting, it appears that the outbreak of Legionnaire’s disease in New York City has been contained. And, if any good came from the outbreak, it is that building owners now need to perform quarterly inspections to insure cooling towers are free of the Legionella bacteria.
The code for Legionalla pneumonia is A48.1, Legionnaire’s disease. You will note that the code for this condition is located in Chapter 1, Certain Infectious and Parasitic Diseases. In ICD-9 the code for Legionnaire’s disease, 48.8, Pneumonia due to other specified bacteria, was located in the chapter for Diseases of the Respiratory system.
You will want to take note of the fact that ICD-10 also provides code A48.2 for nonpneumonic Legionnaire’s disease. A code for this condition was not available in ICD-9.
