Pneumococcal arthritis, left hand

This code signifies an inflammatory joint condition affecting the left hand, specifically caused by Streptococcus pneumoniae bacteria. It represents a bacterial infection leading to arthritis in the joints of the left hand.

Apply this code when documentation confirms a diagnosis of arthritis in the left hand, and laboratory or clinical findings identify Streptococcus pneumoniae as the causative agent. This code is appropriate for cases of septic arthritis where the specific bacterial etiology and affected joint are known.

• Ensure documentation explicitly states "pneumococcal" or identifies Streptococcus pneumoniae as the pathogen.
• Verify the affected joint is specifically the "left hand" to avoid laterality errors.
• Consider additional codes for any associated systemic infection or complications.
