Unspecified bacterial pneumonia
ICD-10 J15.9 is a billable code used to indicate a diagnosis of unspecified bacterial pneumonia.
Unspecified bacterial pneumonia (J15.9) refers to a lung infection caused by bacteria that cannot be precisely identified. Clinically, patients may present with symptoms such as cough, fever, chills, chest pain, and difficulty breathing. The anatomy involved primarily includes the lungs, specifically the alveoli, where the infection leads to inflammation and consolidation. Disease progression can vary; in some cases, it may resolve with appropriate antibiotic treatment, while in others, it can lead to severe respiratory distress or complications such as pleural effusion or sepsis. Diagnostic considerations include a thorough clinical evaluation, chest X-ray or CT imaging to assess lung involvement, and microbiological testing (sputum culture, blood cultures) to identify the causative organism, although in J15.9, the specific pathogen remains unspecified. This code is used when the clinician determines the pneumonia is bacterial but does not specify the organism responsible, often due to the limitations of testing or the clinical context.

J15.9 covers cases of bacterial pneumonia where the specific bacterial pathogen is not identified. This includes pneumonia caused by common bacteria such as Streptococcus pneumoniae, Haemophilus influenzae, and others, but without specification.
J15.9 should be used when a patient is diagnosed with bacterial pneumonia, but the specific organism is unknown or not documented. If the pathogen is identified, more specific codes (e.g., J15.0 for pneumonia due to Streptococcus pneumoniae) should be used.
Documentation should include clinical findings that support a diagnosis of bacterial pneumonia, such as symptoms, imaging results, and any microbiological testing performed. It is essential that the clinical notes indicate the bacterial nature of the pneumonia, even if the specific organism is not identified.
