High-tech Imaging Update for City of Chicago Members

Jan. 21, 2011

The City of Chicago requires benefit authorization through ENCOMPASS Health Management Systems at (800) 373-3727 for prior approval of CAT scans, MRI scans and PET scans.* Claims submitted for these services without prior authorization through ENCOMPASS may be denied. As of Jan. 1, 2011, this applies to the entire City of Chicago group, including non-Medicare Retirees. 

To identify City of Chicago members, look for the CTY alpha prefix on the member's ID card. Group numbers are 016604, P16602, P16605, P16606, P16610, P16628, P16632, P16642, P16643, P17600, P18600, P18601 and P20600. Always refer to the back of the member’s ID card to verify prior authorization requirements and appropriate contact information.

*Note: The City of Chicago is an exception. For most other BCBSIL members with PPO or BlueChoice Select coverage, obtaining a Radiology Quality Initiative (RQI) number through American Imaging Management (AIM) is required by BCBSIL prior to ordering outpatient, non-emergency imaging studies. For complete information on AIM and the RQI process for high-tech imaging services, please visit the Claims and Eligibility/Prior Authorization section.
