Other streptococcal arthritis, unspecified ankle and foot

This code signifies an inflammatory joint condition affecting an unspecified ankle and/or foot, specifically caused by a streptococcal bacterial infection, but not classified as a pyogenic or post-infectious arthritis. It indicates an acute or chronic arthritic process where streptococcus is the identified pathogen.

Apply this code when documentation confirms streptococcal arthritis of the ankle or foot, and the specific type (e.g., pyogenic, post-infectious) is not specified. This is appropriate when the causative organism is identified as streptococcus, and the affected joint is documented as an ankle, foot, or both, without further laterality.

• Ensure documentation explicitly states "streptococcal arthritis" and specifies involvement of the ankle and/or foot.
• Avoid using this code if the documentation specifies pyogenic arthritis or post-infectious arthritis due to streptococcus; more specific codes exist.
• If laterality (right/left) of the ankle/foot is documented, use a more specific code that includes laterality.
