Rupture of synovium, left shoulder

This code signifies a tear or break in the synovial membrane of the left shoulder joint. This typically results in the leakage of synovial fluid, leading to pain, swelling, and impaired joint function. It is an acute injury, often traumatic in nature.

Apply this code when documentation clearly indicates a rupture of the synovium specifically affecting the left shoulder. This diagnosis is often supported by imaging studies such as MRI, arthroscopy findings, or a detailed clinical examination noting signs of synovial fluid extravasation.

• Ensure the documentation specifies "rupture" of the synovium, not just inflammation (synovitis) or other shoulder derangements.
• Verify laterality; this code is specific to the left shoulder.
• Consider sequencing with an external cause code if the rupture is due to trauma.
