Understanding the insurance process can
make a difference

Your doctor’s office will complete a benefits verification on your behalf. They will work with your insurance company to determine if:

GAMMAGARD LIQUID is covered under your health plan
How much insurance will pay
What your deductible will be
How much you will pay out of pocket

Once the office receives this information, ask the office manager to review your benefits verification results with you. This will help you understand what you are responsible for.

Next step: Prior authorization

Your doctor may need to show your health plan that GAMMAGARD LIQUID is the appropriate treatment for you based on your medical profile. This is called a prior authorization.

Your doctor’s office will send the necessary forms and documents to your insurance company
Once your insurance company reviews the prior authorization, you and your doctor’s office will be notified if you are approved for therapy
