Pneumococcal arthritis, right ankle and foot

This code signifies an inflammatory joint condition of the right ankle and foot caused by Streptococcus pneumoniae infection. It represents a bacterial arthritis specifically affecting these lower extremity joints due to pneumococcal etiology.

Apply this code when documentation explicitly states pneumococcal arthritis affecting the right ankle and/or foot. Supporting documentation should include a confirmed diagnosis of Streptococcus pneumoniae as the causative agent and clear identification of the right ankle and foot as the affected sites.

• Ensure the laterality (right) and specific joint involvement (ankle and foot) are clearly documented.
• Do not use this code for unspecified bacterial arthritis or arthritis due to other bacterial organisms.
• Code an additional diagnosis for the underlying pneumococcal infection (e.g., pneumonia, sepsis) if present and documented.
