Transient synovitis, right shoulder

This code signifies a temporary, non-infectious inflammation of the synovial membrane within the right shoulder joint. It is characterized by acute onset of pain and limited range of motion, typically resolving spontaneously without long-term sequelae.

Apply this code when documentation clearly indicates a diagnosis of transient synovitis affecting the right shoulder. This diagnosis is often made after ruling out more serious conditions like septic arthritis or fracture, and is supported by clinical presentation and imaging findings (e.g., joint effusion without signs of infection).

• Ensure laterality (right shoulder) is explicitly documented to support this specific code.
• Distinguish from other forms of synovitis (e.g., M65.811 for other specified synovitis, right shoulder) based on the transient nature.
• Do not use for chronic or recurrent synovitis; those would require different codes.
