Transient synovitis, unspecified elbow

This code signifies a temporary, non-infectious inflammation of the synovial membrane lining the joint capsule of the elbow, without a specified cause. It typically presents with acute pain, swelling, and limited range of motion in the affected elbow. The condition is self-limiting and resolves without residual damage.

Use this code for patients presenting with acute elbow pain and swelling where diagnostic workup rules out trauma, infection, or chronic inflammatory conditions. Documentation should indicate a diagnosis of transient synovitis and specify the affected joint as the elbow, without further laterality or specific cause identified.

• Ensure documentation explicitly states "transient synovitis" and "elbow" for accurate code assignment.
• Avoid using this code if a specific cause (e.g., post-traumatic, infectious) is identified; instead, code the underlying condition.
• If laterality (right or left elbow) is documented, a more specific code (M67.321 or M67.322) should be used.
