Flail joint, right hip

This code describes a flail joint affecting the right hip. A flail joint is characterized by abnormal, excessive, and uncontrolled mobility, often resulting from severe ligamentous laxity, muscle paralysis, or extensive bone loss around the joint, leading to instability and impaired function.

Use this code when documentation clearly indicates a flail joint specifically located in the patient's right hip. This typically occurs following significant trauma, surgical resection (e.g., tumor removal), or severe neuromuscular conditions that compromise joint integrity and stability.

• Ensure the documentation specifies "flail joint" and not just general instability or dislocation, as these are distinct conditions.
• Verify the laterality is explicitly stated as "right hip" to avoid incorrect coding.
• Consider sequencing this code with an underlying cause if known and documented, such as a previous injury or neuromuscular disorder.
