Pneumococcal arthritis, vertebrae

This code signifies an inflammatory joint condition affecting the vertebrae, specifically caused by Streptococcus pneumoniae bacteria. It represents a bacterial infection leading to arthritis in the spinal column.

Apply this code when documentation confirms a diagnosis of pneumococcal arthritis localized to the vertebral column. Supporting documentation should include microbiological identification of S. pneumoniae from joint fluid or tissue, or strong clinical evidence of a bacterial infection with a confirmed pneumococcal source.

• Always confirm the infectious agent is Streptococcus pneumoniae and not another bacterial species.
• Ensure the affected joint is explicitly documented as a vertebra; other joint involvement would require a different code.
• Code an additional code for the underlying pneumococcal infection (e.g., pneumonia) if present and documented.
