Pneumococcal arthritis, unspecified hand

This code signifies an inflammatory joint condition affecting an unspecified hand, specifically caused by Streptococcus pneumoniae bacteria. It represents an infection of the synovial fluid and joint tissues, leading to pain, swelling, and restricted movement in the hand.

Apply this code when documentation confirms a diagnosis of pneumococcal arthritis localized to the hand, but the specific hand (right or left) is not specified. This diagnosis is typically supported by positive joint fluid cultures for S. pneumoniae and clinical signs of septic arthritis.

• Ensure documentation explicitly links Streptococcus pneumoniae as the causative agent for the arthritis.
• If the specific hand (right or left) is documented, use the more specific code (M00.141 for right, M00.142 for left).
• Do not confuse with other forms of infectious arthritis or non-infectious inflammatory arthropathies.
