Other streptococcal arthritis, right ankle and foot

This code signifies an inflammatory joint condition affecting the right ankle and/or foot, specifically caused by a streptococcal bacterial infection. It indicates an acute or chronic arthritic process where streptococcus is identified as the causative agent.

Apply this code when documentation confirms streptococcal arthritis localized to the right ankle and/or foot. This typically involves positive cultures for streptococcus from joint fluid or blood, coupled with clinical signs of arthritis in the specified joint.

• Ensure documentation clearly specifies "other" streptococcal arthritis, as opposed to specific types like scarlet fever arthritis.
• Verify laterality (right ankle/foot) is explicitly stated in the physician's notes.
• Code an underlying streptococcal infection (e.g., cellulitis, pharyngitis) if present and documented as the source.
