Hemarthrosis, left ankle

This code signifies the presence of blood within the joint space of the left ankle. This condition, known as hemarthrosis, often results in pain, swelling, and limited range of motion in the affected joint. It indicates an acute or chronic accumulation of blood, distinct from other forms of joint effusion.

Use this code when documentation clearly states hemarthrosis affecting the left ankle. This typically occurs following trauma, such as a sprain or fracture, or in patients with coagulopathies or bleeding disorders. Supporting documentation should include physician notes detailing the diagnosis of hemarthrosis and specifying the left ankle as the affected site.

• Ensure the documentation specifies "hemarthrosis" and not just "effusion" or "swelling" to accurately assign this code.
• Verify the laterality; this code is specific to the left ankle.
• Always code any underlying cause of the hemarthrosis, such as a fracture or bleeding disorder, as a primary diagnosis if applicable.
