Coverage verification and pre-authorization:

After you and your provider decide which treatment you will have – CyberKnife or Gamma Knife – our financial counselor will work with your insurance company to verify your benefits.If your insurance plan requires a pre-authorization, we will request one. Obtaining a pre-authorization may take several days - or even weeks.

Although coverage verification and pre-authorization give you permission to go forward with the treatment, it does not guarantee your insurance company will pay the cost of treatment. We will require you to sign a waiver accepting financial responsibility in the event your insurance company denies payment. We encourage you to call your insurance plan administrator to determine how much your insurance company will pay and how much of the bill will be your responsibility.

Denied pre-authorization:

If your insurance plan requires but denies authorization, our financial counselor will work with your doctor to provide the insurance company more information about why radiosurgery treatment is medically necessary.

If we receive pre-authorization, we will proceed with your treatment plan. If your insurance again denies authorization, you have the right to appeal the decision. We will help you with your appeal by providing detailed information regarding your medical condition and the radiosurgery treatment you and your doctor have chosen.

If you are having CyberKnife treatment, additional assistance may be available through Accuray, the company that manufactures the CyberKnnife equipment, by calling Accuray Patient Relations at 888-522-3740. For tips on appealing a denial for authorization for CyberKnife treatment, go to

Billing process for patients with insurance

There are several steps to the billing process for services at the Swedish Radiosurgery Center:

Step 1. We will send you a notice when we submit a bill to your insurance company for payment.

Step 2. After your insurance company processes the bill for payment, they will send you an explanation of benefits (EOB) that shows you what they have paid and any payment you owe. If you have questions about your insurance company's explanation of benefits, please call them directly for assistance.

Step 3. After we receive payment from your insurance company, we will send you a bill for your portion of the payment.

Billing process for patients without insurance

If you do not have insurance and have not paid in advance, we will bill you directly for services provided.
