Transient synovitis, left hand

This code describes a temporary, non-infectious inflammation of the synovial membrane lining the joints of the left hand. It typically presents with acute pain, swelling, and tenderness, often resolving spontaneously without long-term sequelae.

Apply this code when documentation specifies transient synovitis affecting the left hand. Supporting documentation should indicate acute onset of symptoms, absence of trauma or infection, and a self-limiting course.

• Ensure laterality is clearly documented as "left hand" to avoid miscoding.
• Differentiate from other forms of synovitis (e.g., infectious, traumatic) which have distinct codes.
• Do not use for chronic or recurrent synovitis; those conditions require more specific codes.
