Subacute and chronic melioidosis

This code represents a persistent or recurring infection caused by the bacterium Burkholderia pseudomallei, characterized by symptoms lasting longer than two months or by a relapsing course. It can manifest with various organ system involvement, such as abscesses in the liver, spleen, or prostate, osteomyelitis, or chronic pneumonia.

Assign this code when documentation specifies melioidosis that is subacute (symptoms present for weeks to months) or chronic (symptoms persisting for months to years, or recurrent episodes). Supporting documentation will typically include microbiology reports confirming B. pseudomallei and physician notes detailing the prolonged or relapsing nature of the infection.

• Differentiate from acute melioidosis, which has a more rapid onset and progression.
• Code any associated manifestations or complications of the melioidosis, such as pneumonia or abscesses, as additional diagnoses.
• Ensure the medical record clearly distinguishes between initial acute infection and subsequent subacute or chronic phases.
