Other streptococcal arthritis, left wrist

This code signifies an inflammatory joint condition affecting the left wrist, specifically caused by a streptococcal bacterial infection, but not classified as a primary pyogenic arthritis. It indicates an infectious arthritis where streptococcus is the causative agent, leading to pain, swelling, and reduced function in the joint.

Apply this code when documentation confirms streptococcal arthritis localized to the left wrist, and the infection is not explicitly described as pyogenic. This typically occurs following a streptococcal infection elsewhere in the body, such as strep throat, leading to a reactive or post-infectious arthritis. Supporting documentation includes positive streptococcal cultures, elevated inflammatory markers, and imaging findings consistent with arthritis in the left wrist.

• Ensure documentation specifies "streptococcal" as the causative organism and "left wrist" as the affected joint.
• Distinguish from primary pyogenic arthritis (M00.0-) or other bacterial arthritides (M00.8-).
• Code an underlying streptococcal infection (e.g., pharyngitis) if still active and documented.
