Unspecified synovitis and tenosynovitis, unspecified hand

This code represents inflammation of the synovial membrane (synovitis) or the tendon sheath (tenosynovitis) affecting an unspecified hand. It indicates that the specific type of synovitis or tenosynovitis, as well as the laterality of the hand, is not documented.

Use this code when documentation clearly indicates synovitis or tenosynovitis of the hand, but the specific cause (e.g., infectious, crystal-induced) and the affected hand (right or left) are not specified. This code is appropriate when the provider's diagnosis is simply "synovitis of hand" or "tenosynovitis of hand" without further detail.

• Avoid using this code if laterality (right or left hand) is documented; instead, use a more specific code.
• Query the provider for more specific information regarding the type of synovitis/tenosynovitis and laterality if possible.
• This code should be used when no other more specific code for synovitis or tenosynovitis of the hand can be assigned.
