Other infective (teno)synovitis, left wrist

This code signifies an inflammation of the synovial lining of a tendon sheath, or the joint capsule itself, in the left wrist, caused by an infectious agent other than those specified in more granular codes. This condition typically presents with pain, swelling, and restricted movement in the affected wrist.

Apply this code when documentation specifies infective tenosynovitis or synovitis of the left wrist, and the causative organism is not explicitly identified as staphylococcal, streptococcal, or another specific pathogen with its own dedicated code. This code is appropriate when the infection is confirmed but the specific type of infection is not further detailed.

• Ensure documentation clearly specifies "left wrist" and an "infective" etiology.
• Differentiate from non-infective tenosynovitis (M65.8) or synovitis (M65.9) of the wrist.
• Always sequence this code after the underlying infectious disease code, if known and applicable.
