Pneumonia due to mycoplasma pneumoniae

This code identifies pneumonia specifically caused by the bacterium Mycoplasma pneumoniae. This type of pneumonia is often referred to as "walking pneumonia" due to its typically milder symptoms compared to other bacterial pneumonias. It involves inflammation of the lung tissue, leading to respiratory symptoms.

Use this code when documentation clearly states a diagnosis of pneumonia and specifies Mycoplasma pneumoniae as the causative organism. This diagnosis is typically supported by laboratory test results (e.g., PCR, serology) confirming the presence of Mycoplasma pneumoniae or a strong clinical suspicion in the absence of other identified pathogens.

• Ensure the physician's documentation explicitly links Mycoplasma pneumoniae as the etiology of the pneumonia.
• Do not use this code for pneumonia of unspecified etiology or pneumonia due to other bacterial organisms.
• Consider sequencing this code as the primary diagnosis if it is the reason for the encounter, followed by any associated complications.
