Other synovitis and tenosynovitis, left hand

This diagnosis code signifies inflammation of the synovial membrane (synovitis) or the tendon sheath (tenosynovitis) in the left hand, when the specific type of synovitis or tenosynovitis is not otherwise classified. It indicates a non-specific inflammatory process affecting these structures.

Apply this code when documentation specifies synovitis or tenosynovitis of the left hand, and a more specific diagnosis code (e.g., infectious, crystal-induced) is not provided. This code is appropriate for conditions like non-specific inflammatory tenosynovitis or synovitis of the wrist or fingers of the left hand.

• Ensure the documentation clearly specifies "left hand" to support laterality.
• Always look for more specific codes first; this is a "catch-all" for other specified types.
• Do not use if a definitive cause (e.g., infectious, traumatic, rheumatoid) is documented, as more specific codes exist for those etiologies.
