Hemarthrosis, left foot

This code signifies the presence of blood within the joint space of the left foot. This condition often results from trauma, bleeding disorders, or complications following surgery, leading to pain, swelling, and limited range of motion in the affected foot joint.

Apply this code when documentation explicitly states hemarthrosis affecting the left foot. This is typically supported by imaging findings (e.g., MRI, ultrasound) confirming intra-articular hemorrhage, or by aspiration of bloody fluid from a left foot joint.

• Ensure laterality is clearly documented as "left foot" to avoid unspecified coding.
• Always code the underlying cause of the hemarthrosis (e.g., trauma, coagulopathy) as a primary diagnosis when known.
• Distinguish from other forms of joint effusion (e.g., serous, purulent) which would require different codes.
