High End Imaging - Cardiac imaging and elective heart catheterization

Last Updated on July 01, 2022

High end imaging

Security Health Plan requires prior notification for outpatient high-end imaging tests for cardiac  imaging and elective heart catheterization. A complete list of CPT codes requiring notification can be found below.  Services performed without authorization may be denied for payment; and you may not seek reimbursement from members.

Marshfield Clinic rendering providers should contact Security Health Plan to obtain prior authorization of the cardiac services for members. 

A prior notification is required for affiliated providers, facilities and ancillary providers for aforementioned high-end imaging procedures prior to performance, with administrative claim denial for non-compliance. The ordering provider maintains final decision authority of which high-end imaging test is performed. If an affiliated provider fails to prior notify, retro-notification will not be accepted.

The ordering provider or designee is responsible for obtaining a notification number prior to scheduling high-end outpatient imaging procedures. Prior notification can be completed on-line via Security Health Plan’s provider portal.

Authorization is required for:

  • Cardiac Advanced Imaging: CT, MR, PET
  • Nuclear Cardiology (includes nuclear stress testing)
  • Echo Stress Testing
  • Echocardiography
  • Diagnostic Heart Catheterization
