Transient synovitis, right hand

This code describes a temporary, non-infectious inflammation of the synovial membrane lining the joint capsule of the right hand. It typically presents with acute onset of pain, swelling, and limited range of motion in the affected hand, often resolving spontaneously within a few days to weeks.

Apply this code when documentation specifies transient synovitis affecting the right hand. This diagnosis is often made after ruling out other causes of hand pain and swelling, such as infection, trauma, or chronic inflammatory conditions. Supporting documentation should include a clear diagnosis from the provider and laterality.

• Ensure the documentation explicitly states "transient synovitis" and specifies the "right hand."
• Do not use this code for chronic synovitis or synovitis due to a specific underlying condition (e.g., rheumatoid arthritis, infection).
• Verify laterality; codes exist for the left hand (M67.342) and unspecified hand (M67.349).
