Other synovitis and tenosynovitis, unspecified shoulder

This code signifies inflammation of the synovial membrane (synovitis) or the tendon sheath (tenosynovitis) affecting an unspecified shoulder joint. It indicates a non-specific inflammatory process within the shoulder, without further detail regarding the specific type of synovitis or tenosynovitis.

Use this code when documentation clearly indicates synovitis or tenosynovitis of the shoulder, but the laterality (left or right) is not specified. It is appropriate when the provider's diagnosis is general and does not pinpoint a more specific type of inflammation.

• Avoid using this code if the documentation specifies the affected shoulder (e.g., "right shoulder synovitis"); instead, use the more specific laterality code.
• Query the provider if the specific type of synovitis or tenosynovitis (e.g., infectious, crystal-induced) is known but not documented.
• This code should be used when no other, more specific code for shoulder synovitis or tenosynovitis can be assigned based on the available documentation.
