(Active) Effective Date: N/A Infectious and parasitic diseases - Other bacterial diseases Certain infectious and parasitic diseases Feed
Whooping cough due to Bordetella parapertussis with pneumonia.
Medical necessity is established by the presence of whooping cough due to B. parapertussis and pneumonia, confirmed through clinical findings, laboratory testing, and imaging studies.Treatment is medically necessary to address the bacterial infection and respiratory complications.
Physicians should diagnose based on symptoms (cough, difficulty breathing, whooping sound, vomiting, fever), history, physical exam, and lab tests (blood and mucus cultures). Imaging (chest x-ray, CT scan) may be necessary for pneumonia. Treatment includes antibiotics and supportive care (oxygen, monitoring). Hospitalization is often required for patients with pneumonia.
In simple words: This code indicates whooping cough (pertussis) caused by a specific bacteria called Bordetella parapertussis, along with lung infection (pneumonia).
Whooping cough, also known as pertussis, is a highly contagious bacterial respiratory disease less commonly caused by Bordetella parapertussis.It's characterized by severe coughing fits followed by a "whooping" sound during inhalation. This code specifies that the whooping cough is caused by B. parapertussis and is complicated by pneumonia.
Example 1: A 2-month-old infant presents with a cough, runny nose, and low-grade fever for the past week. The cough has worsened, with episodes of rapid coughs followed by a whooping sound and vomiting. A chest x-ray reveals pneumonia. Lab tests confirm B. parapertussis. Code A37.11 is assigned., A 5-year-old child with a history of mild respiratory symptoms develops severe coughing fits with a whooping sound, especially at night. The child also exhibits high fever, difficulty breathing, and decreased appetite.A chest x-ray confirms pneumonia, and B. parapertussis is identified.Code A37.11 is assigned., An adult patient presents with persistent cough, shortness of breath, and fever. A chest x-ray shows signs of pneumonia. After further investigation, including laboratory tests, the diagnosis is whooping cough due to B. parapertussis with pneumonia. Code A37.11 is assigned.
Documentation should include signs and symptoms (cough, whooping sound, fever, difficulty breathing, vomiting), lab results confirming B. parapertussis, and imaging results (chest x-ray, CT scan) confirming pneumonia. Details of treatment provided (antibiotics, oxygen therapy, hospitalization) should also be documented.
