I get IVIG 3x / week for a primary immune deficiency I’ve had since birth. For my dosage, it’s billed weekly at a rate of ~$32K of which my insurance company pays around ~$3K.
I hit my max out of pocket the first month of each year and the rest of the year is “free.”
I know that all the IVIG pharmaceutical companies offer a “I can’t afford this” option if you’re going out of pocket.
Good luck, it’s stressful to get but it’s a miracle blood product for those who need it.
