Cancer Care


We require authorization or pre-approval for inpatient requests for cancer treatment services for all members. Notification to Blue Cross is required. Go to our Prior Authorization Overview page for tips for submitting authorization requests

For FEP members, please check authorization requirements at fepblue.org.


Commercial and Medicare Advantage members

We require prior authorization for certain outpatient medical oncology and radiation oncology services through our Quality Care Cancer Program. The program is administered by Carelon Medical Benefits Management (formerly AIM Specialty Health), an independent company, so authorization requests should go directly to them.

Note: Indemnity members are not part of the Quality Care Cancer Program.
