Pneumonia due to coronavirus disease 2019

This code signifies pneumonia directly caused by the SARS-CoV-2 virus, the pathogen responsible for COVID-19. It represents a specific respiratory complication where the viral infection has progressed to inflammation and fluid accumulation in the lungs.

Apply this code when documentation explicitly states "COVID-19 pneumonia" or "pneumonia due to SARS-CoV-2." This diagnosis is typically supported by positive COVID-19 test results alongside clinical and radiological evidence of pneumonia (e.g., chest X-ray findings, symptoms like cough, dyspnea, fever).

• Always sequence this code after the primary diagnosis code for COVID-19 (U07.1).
• Do not use this code for pneumonia from other causes in a patient with COVID-19; ensure a direct causal link is documented.
• Distinguish from other viral pneumonias (J12.x) or bacterial pneumonias (J18.x) where COVID-19 is not the etiology.
