Other infective (teno)synovitis, right wrist

This code signifies inflammation of the synovial sheath surrounding tendons in the right wrist, caused by an infectious agent. This condition typically presents with pain, swelling, and restricted movement in the affected wrist due to bacterial, viral, or fungal invasion of the tenosynovial space.

Apply this code when documentation clearly indicates an infective etiology for tenosynovitis affecting the right wrist. This includes cases confirmed by culture, Gram stain, or strong clinical suspicion of infection, such as purulent discharge or systemic signs of infection.

• Ensure documentation specifies "infective" and not just inflammatory or traumatic tenosynovitis.
• Verify laterality (right wrist) is clearly stated in the medical record.
• Distinguish from non-infectious tenosynovitis (e.g., M65.831) or other inflammatory arthropathies of the wrist.
