Unspecified synovitis and tenosynovitis, other site

This code represents inflammation of the synovial membrane (synovitis) or the tendon sheath (tenosynovitis) in an unspecified anatomical location other than the hand or foot. It indicates a generalized inflammatory process affecting these structures without a more specific site identified.

Use this code when documentation clearly indicates synovitis or tenosynovitis but the specific anatomical site is not documented, or it affects a site not covered by more specific codes (e.g., shoulder, knee, hip, elbow, wrist, ankle). This code is appropriate when the provider has diagnosed the condition but lacks the specificity for a more granular code.

• Avoid using this code if a more specific anatomical site (e.g., hand, foot, shoulder) is documented; always strive for the highest level of specificity.
• Query the provider for a more precise anatomical location if possible to allow for a more specific code assignment.
• Consider codes from categories M65.0-M65.8 if the specific type of synovitis/tenosynovitis (e.g., infective, calcific, other specified) is known and documented.
