Hemarthrosis, left hand

This code signifies the presence of blood within the joint space of the left hand. This condition often results from trauma, but can also be associated with bleeding disorders, anticoagulant use, or inflammatory arthropathies. It typically presents with acute pain, swelling, and limited range of motion in the affected hand joint.

Apply this code when documentation explicitly states hemarthrosis affecting any joint of the left hand. Supporting documentation should detail the presence of blood in the joint, often confirmed by aspiration or imaging. This diagnosis is commonly seen following fractures, sprains, or direct impact injuries to the hand.

• Ensure laterality is clearly documented as "left hand" to support this specific code.
• Do not confuse with hemarthrosis of other upper extremity joints (e.g., wrist, elbow, shoulder).
• Code any underlying cause (e.g., fracture, bleeding disorder) as a primary diagnosis if applicable, with hemarthrosis as a secondary diagnosis.
