Cardiac event monitoring prior authorization change

Last Update: Aug. 30, 2022

Effective Feb. 1, 2022, we will update our cardiology prior authorization program to include codes related to implantable loop recorders for UnitedHealthcare Medicare Advantage members.

The following codes will require prior authorization: CPT® 33285 and HCPCS E0616.

You can request prior authorization:

  • Online: Go to
  • By phone: Call 877-842-3210 from 7 a.m.–7 p.m. local time, Monday–Friday

We’ll contact the requesting health care professional and member with our coverage decision within 15 calendar days, or sooner based on applicable regulations. If we deny coverage, we’ll include appeal information in the denial letter.

If you don’t complete a prior authorization before performing a procedure, we’ll deny the claim, and you won’t be able to bill the member for the services.

Please contact your network representative or visit our Contact Us page.
