Other forms of nocardiosis

This code signifies a diagnosis of nocardiosis that does not fit into the more specific categories of pulmonary, cutaneous, or disseminated forms. It encompasses less common or atypical presentations of infection caused by Nocardia species, which are aerobic actinomycetes. These infections can affect various organ systems, often in immunocompromised individuals.

Assign this code when the medical record clearly documents nocardiosis, but the specific site of infection is not pulmonary, cutaneous, or disseminated, or when the infection presents in an unusual or unclassifiable manner. Documentation should specify "other nocardiosis" or describe a site not covered by more specific codes (e.g., cerebral nocardiosis without systemic dissemination, renal nocardiosis).

• Ensure the documentation explicitly rules out pulmonary, cutaneous, or disseminated nocardiosis before assigning this code.
• Always look for specific site documentation; if available, a more precise code within A43.0-A43.2 may be appropriate.
• Consider sequencing this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis if it's a co-morbidity.
