Pneumococcal arthritis, right wrist

This code signifies an inflammatory joint condition of the right wrist caused by a Streptococcus pneumoniae bacterial infection. It represents a specific type of septic arthritis where the pneumococcus bacterium is identified as the causative agent affecting this particular joint.

Apply this code when documentation explicitly states pneumococcal arthritis affecting the right wrist. This typically occurs in patients with a history of pneumococcal infection or risk factors, presenting with acute onset of pain, swelling, and limited range of motion in the right wrist, confirmed by joint fluid analysis identifying S. pneumoniae.

• Ensure the documentation specifies "pneumococcal" as the etiology and "right wrist" as the affected joint.
• Do not confuse with other bacterial arthritides or non-infectious inflammatory arthropathies.
• Code an additional code for the underlying pneumococcal infection (e.g., pneumonia) if present and documented.
