Pneumonia due to staphylococcus aureus
ICD-10 J15.21 is a used to indicate a diagnosis of pneumonia due to staphylococcus aureus.
Pneumonia due to Staphylococcus aureus is a type of lung infection characterized by inflammation of the lung parenchyma caused by the Staphylococcus aureus bacterium. Clinically, patients may present with symptoms such as fever, cough, chest pain, and difficulty breathing. The infection can be particularly severe in individuals with weakened immune systems, chronic lung diseases, or those who have recently undergone surgery. The anatomy involved primarily includes the alveoli and bronchi, where the infection leads to consolidation and impaired gas exchange. Disease progression can vary; it may start with mild symptoms but can rapidly escalate to severe respiratory distress, necessitating hospitalization. Diagnostic considerations include chest X-rays or CT scans to identify infiltrates, along with sputum cultures to confirm the presence of Staphylococcus aureus. Blood cultures may also be performed to detect bacteremia, which can occur in severe cases.

J15.21 specifically covers pneumonia caused by Staphylococcus aureus, which can manifest as community-acquired or hospital-acquired pneumonia, including cases associated with methicillin-resistant Staphylococcus aureus (MRSA).
J15.21 should be used when the pneumonia is confirmed to be due to Staphylococcus aureus, as indicated by culture results. It should not be used for pneumonia caused by other organisms or when the causative agent is unknown.
Documentation should include clinical findings, laboratory results confirming Staphylococcus aureus, imaging studies showing pneumonia, and treatment plans. Clear notes on the patient's history and any comorbidities are also essential.
