As always, your insurer and your insurance policy can affect coverage for any drugs your doctor prescribes, including treatments that you receive on a regular basis, such as Ig. Many insurance companies have a list of prescription medications that they will cover under the benefit plan. This list is called a formulary. It's important to know if the drugs you take are on your insurance carrier's formulary. Check the formulary by visiting your insurance company's web page, and see if the drug your doctor prescribes is listed. Also look to see if the list includes the type of drug you receive, as well as the specific brand your doctor recommends. Sometimes insurance formularies will list only some of the brands that are available for a medication. If your brand of medication is—or is not—on the formulary, it can affect how much money you or your family will have to pay for the drug as out-of-pocket costs or copays.
