Other synovitis and tenosynovitis, multiple sites

This code represents inflammation of the synovial membrane or tendon sheath affecting multiple, distinct anatomical locations. It describes a non-specific inflammatory process impacting several joints or tendons throughout the body, not limited to a single site.

Apply this code when documentation specifies synovitis or tenosynovitis occurring in more than one joint or tendon, and a more specific code for the underlying cause or specific site is not available. Supporting documentation should clearly indicate involvement of multiple, distinct anatomical sites.

• Ensure documentation explicitly states "multiple sites" or lists several affected areas.
• Do not use this code if a more specific code for the underlying etiology (e.g., rheumatoid arthritis with synovitis) or a single, specified site is available.
• Consider sequencing with codes for associated conditions or underlying systemic diseases if applicable.
