Hemarthrosis, left hip

This code signifies the presence of blood within the joint space of the left hip. This condition often results from trauma, bleeding disorders, or anticoagulant use, leading to pain, swelling, and restricted range of motion in the affected hip.

Assign this code when documentation clearly indicates hemarthrosis specifically affecting the left hip joint. This diagnosis is typically supported by imaging studies (e.g., MRI, ultrasound) showing intra-articular blood, or by aspiration of bloody synovial fluid from the left hip.

• Ensure laterality is explicitly documented as "left hip" to avoid incorrect coding.
• Distinguish from other forms of hip effusion (e.g., serous, purulent) which have different codes.
• Code any underlying cause of the hemarthrosis (e.g., fracture, coagulopathy) as an additional diagnosis.
