Other streptococcal arthritis, left ankle and foot

This code signifies an inflammatory joint condition affecting the left ankle and/or foot, specifically caused by a streptococcal bacterial infection. It indicates a non-pyogenic (non-pus-forming) arthritis resulting from the body's immune response to a streptococcal infection elsewhere in the body, or a direct infection of the joint.

Apply this code when documentation clearly states a diagnosis of streptococcal arthritis localized to the left ankle and/or foot. This typically follows a recent streptococcal infection (e.g., strep throat, skin infection) and presents with joint pain, swelling, and limited range of motion in the specified area. Supporting documentation should include laboratory findings confirming streptococcal presence or a history of recent streptococcal infection.

• Ensure the documentation specifies "other" streptococcal arthritis, distinguishing it from post-infectious or reactive arthritis.
• Verify the laterality is explicitly stated as "left ankle and foot" to avoid incorrect assignment.
• Code the underlying streptococcal infection first, if still active, followed by this code for the arthropathy.
