Other infective (teno)synovitis, right knee

This code signifies inflammation of the synovial membrane and/or tendon sheath in the right knee, specifically caused by an infectious agent other than a bacterial, viral, or parasitic infection explicitly classified elsewhere. It represents an inflammatory response within the joint or surrounding tendons due to an unspecified or less common infectious etiology.

Apply this code when documentation clearly indicates infective tenosynovitis or synovitis affecting the right knee, and the specific infectious organism is not identified or falls outside the categories for which more specific codes exist. Supporting documentation should include physician notes detailing the infectious nature of the inflammation and its localization to the right knee.

• Ensure documentation specifies "infective" and not just inflammatory to differentiate from non-infectious causes.
• Verify laterality (right knee) is clearly documented; separate codes exist for the left and bilateral knees.
• Always look for a more specific infectious agent code if identified (e.g., bacterial, viral) before defaulting to "other infective."
