Rupture of synovium, right ankle

This code signifies a spontaneous or traumatic tearing of the synovial membrane specifically within the right ankle joint. This rupture can lead to leakage of synovial fluid, causing pain, swelling, and impaired joint function. It represents an acute injury to the joint lining.

Use this code when documentation clearly indicates a rupture of the synovium affecting the right ankle. This diagnosis is typically supported by imaging studies (e.g., MRI) and clinical examination findings consistent with synovial disruption. It applies to both acute injuries and spontaneous ruptures.

• Ensure laterality is explicitly documented as "right ankle" to support this specific code.
• Distinguish from other ankle injuries like ligamentous tears or tendon ruptures, which have different codes.
• Look for documentation of the cause (e.g., trauma, degenerative changes) as this may influence other codes.
