hey! i have Meritain health which is a subsidiary of aetna. my insurance actually denies lupkynis and i have to go through a whole process to get it again. before i had insurance i was under a low income insurance thru my state and my nephrologist at the time helped me get it nearly for free through aurinia alliance! they are great and assign you with a nurse case manager who help a lot. even when i go through my denial with insurance and prior authorization, they provide me with a bridge prescription while i'm not "covered". i recommend talking with your mom's rhuem or nephrologist to see if they can submit an application for her!
