Rupture of synovium, left foot

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

Apply this code when documentation clearly states a rupture of the synovium specifically located in the left foot. This diagnosis is supported by findings such as joint effusion, tenderness, and imaging (e.g., MRI) confirming synovial membrane disruption. Use for acute traumatic or non-traumatic ruptures.

• Ensure the documentation specifies "rupture" and not merely inflammation (synovitis) or other synovial disorders.
• Verify the laterality is explicitly stated as "left foot"; avoid using unspecified laterality codes if this information is available.
• Look for an external cause code (V00-Y99) if the rupture is due to an injury, and sequence it after the M code.
