J15.7

What This Code Means

This is a lung infection caused by a specific bacterium called Mycoplasma pneumoniae, which typically causes a mild to moderate pneumonia often called 'walking pneumonia' because patients can sometimes continue their daily activities despite being sick.

Coding Tips

• •Ensure the documentation specifically identifies Mycoplasma pneumoniae as the causative organism; do not use this code for pneumonia of unspecified organism
• •This code is more specific than general pneumonia codes, so use it when the organism is confirmed through culture, PCR, or serological testing rather than presumptive diagnosis
