From Our Advocates: We've seen cases where patients initially denied Xyrem coverage succeeded on appeal by providing more detailed sleep study documentation and clearer evidence of prior medication failures. The key is often demonstrating that standard treatments genuinely didn't work, not just that they were tried briefly.
