Other infective (teno)synovitis, right hand

This code signifies inflammation of the synovial sheath surrounding tendons, or the synovial membrane of a joint, in the right hand, specifically caused by an infection. It indicates a non-bacterial or non-specific infectious etiology, differentiating it from conditions like pyogenic tenosynovitis.

Apply this code when documentation specifies infective tenosynovitis or synovitis affecting the right hand, and the infection is not explicitly bacterial (e.g., staphylococcal, streptococcal). Supporting documentation should clearly state the anatomical site (right hand) and the infectious nature without specifying a bacterial organism.

• Ensure the documentation specifies "right hand" to avoid laterality errors.
• Distinguish from M65.0- (Pyogenic tenosynovitis) if a specific bacterial infection is identified.
• Consider an additional code for the underlying infectious agent if known and documented (e.g., B95-B97).
