Transient synovitis, left wrist

This code represents a temporary, non-infectious inflammation of the synovial membrane lining the left wrist joint. It is characterized by acute onset of pain, swelling, and limited range of motion, typically resolving spontaneously within days to weeks. The condition is often idiopathic but can follow minor trauma or viral illness.

Apply this code for patients presenting with symptoms consistent with transient synovitis affecting the left wrist, where infectious or chronic inflammatory causes have been ruled out. Documentation should clearly indicate the transient nature of the synovitis and its specific anatomical location.

• Ensure documentation specifies "transient" to differentiate from other forms of synovitis.
• Verify the laterality (left wrist) is clearly stated in the medical record.
• Do not use this code if a specific underlying cause for the synovitis (e.g., infection, crystal arthropathy, autoimmune disease) has been identified; instead, code the underlying condition.
