Frequently Asked Questions

About PERJETA Access Solutions

PERJETA Access Solutions is a resource for people who take a Genentech medicine. We connect you to the medicine you need.

I Am Concerned About Paying for PERJETA

There may be options to help you get the Genentech medicine your doctor has prescribed. PERJETA Access Solutions can refer you to patient assistance options.

We have changed the name of GATCF to the Genentech Patient Foundation. We made this change to show our commitment to helping patients and to make it easier to remember.

Getting My Medicine

You might not be able to get your Genentech medicine right away. First, your doctor’s office or specialty pharmacy will have to check to make sure your health insurance plan covers your medicine. This is called a “benefits investigation.” They also might have to send some more information before your plan covers your medicine. This is called a “prior authorization.”

Enrolling in PERJETA Access Solutions

  1. You fill out a form called the PAN.
  2. Your doctor fills out a form called the Prescriber Service Form. You do not have to fill out anything on this form.
  3. Your doctor sends both of these forms to PERJETA Access Solutions.

There are 2 ways to fill out the PAN form:

  • You can fill out the form online 
  • You can download and print it to fill out a paper copy

The PAN form lets us discuss your health information with your doctor and your health insurance plan. We can’t work with you without a signed PAN.

You do not need to do anything else, but your doctor does. He or she needs to submit a form called the Prescriber Service Form. This form tells us your doctor wants to treat you with PERJETA. Make sure your doctor has sent us the Prescriber Service Form so you get help from us.

You do not need to fill out anything on the Prescriber Service Form.

My Health Plan Denied Coverage for PERJETA

If your health insurance plan will not cover your Genentech medicine, you and your doctor’s office can file an appeal. Contact your doctor to ask if you should file an appeal.

We have resources to help you and your doctor file an appeal.

We have resources to help you and your doctor file an appeal. You or your doctor’s office has to file the appeal directly with your health insurance plan.

This depends on your health insurance plan. You should ask your plan directly about its process. Sometimes the appeals process is quick. However, it can take several months if you have to appeal several times.

My Insurance Might Change

If your insurance changes while you’re taking your Genentech medicine, call us. We can help you understand your new coverage.

The Genentech Patient Foundation gives free Genentech medicine to people who don't have insurance coverage or who have financial concerns and to people who meet certain income criteria.

It is your and your doctor's responsibility to complete and submit all required paperwork to your health insurance plan. Genentech cannot guarantee your plan will cover any treatments.
