Flail joint, right wrist

This code signifies a flail joint affecting the right wrist. A flail joint is characterized by abnormal, excessive, and uncontrolled mobility, often resulting from severe ligamentous laxity, muscle paralysis, or bone loss, leading to instability and functional impairment of the joint.

Apply this code when documentation clearly indicates a diagnosis of a flail joint specifically located in the patient's right wrist. This typically arises from conditions like severe trauma, neuromuscular disorders, or extensive surgical resections that compromise joint integrity.

• Ensure documentation specifies "flail joint" and not just general instability or hypermobility, as these are distinct conditions.
• Verify the laterality is explicitly stated as "right wrist" to avoid incorrect coding.
• Code any underlying cause or associated conditions, such as nerve injury or fracture nonunion, in addition to this code.
