Radiology services requests

Advanced imaging services

Advanced imaging includes CT, CTA, MRA, MRI, and PET services. Submit your request through the Referral Request tool 

Puget Sound region providers: All radiology requests for services at a Kaiser Permanente facility must include a completed Radiology imaging request form (PDF)

*Radiology requests for MRIs must also include a completed MRI questionnaire (PDF)

Kaiser Permanente requires prior authorization for computed tomography (CT), magnetic resonance imaging (MRI), magnetic resonance angiography (MRA), and positron emission tomography (PET) services to ensure clinically appropriate imaging for our members.

Note: Claims adjudication requires prior authorization for payment. If no authorization is present, we will deny the claim to the provider's financial liability. The denial will impact the rendering provider's claims; that is, the provider providing the imaging service, not the provider ordering the service.

To expedite patient care, please check the CPT code in the PreAuthorization Code Check Tool. The tool will inform you if an authorization is needed. If it is needed and there is documentation indicated for the review, please attach those records to your referral request in Affiliate Link.
