From Our Advocates

We've seen many Thiola appeals succeed when families take time to gather complete medical records before submission. One common mistake is submitting incomplete 24-hour urine studies—make sure your collection includes start/end times and total volume measurements. Having a urologist involved from the start significantly improves approval odds, as they understand the specialized documentation Aetna requires for rare kidney stone conditions.
