Understanding Your Insurance
ENHERTU4U can help you understand your insurance coverage. Knowing this information may simplify the process of getting your prescription. Your doctor will work with us to complete the required steps. Here are some of the offerings we provide that may help you:
Benefits Review
We will conduct a benefits review to determine what is covered by your insurance plan, whether there may be restrictions, and how much you may need to pay (out-of-pocket expense) to get your medication. A benefits review determines whether your payer requires a Prior Authorization (PA).
Prior Authorization
A PA is a verification from your doctor that states that your medication is medically necessary. Your insurance company may require a PA in order to cover certain medications. We will help your doctor understand what information may be needed.
Claims Appeals
If the insurance company denies your ENHERTU prescription, we can give your doctor information about how to appeal the insurance company’s decision.
Paying for Your ENHERTU Prescription
If you cannot afford your out-of-pocket costs for ENHERTU, we may have programs that can help.
