  • Advanced Radiology Imaging
  • Musculoskeletal – Pain/Joint/Spine
  • Outpatient Medical Oncology
  • Outpatient Radiation Therapy
  • Outpatient Sleep
  • Outpatient Specialty Drug
  • Lab Management Solutions – Molecular and Genomic Lab Testing

As of December 9th, 2022, providers can submit eviCore prior authorization requests for services for dates of service Jan. 1, 2023 and after.

To request an authorization: 

  • Log onto (preferred method)
  • Call: 1-855-252-1117 (7 am – 7 pm local time, M-F)
  • Fax: 1-800-540-2406

For urgent requests: If services are required in less than 48 hours due to medically urgent conditions, please submit a request online at eviCore and indicate the procedure is NOT routine/standard. Providers can also request urgent requests by calling the toll-free number at 1-855-252-1117. Be sure to tell the representative the request is for medically urgent care.

We recommend ordering physicians request authorization and pass the approval information to the rendering facilities at the time of scheduling.  Authorizations contain approval numbers and one or more CPT codes specific to the services authorized. If the service requested and/or performed is different than what was initially authorized, the rendering facility must contact eviCore to make revisions to the authorization prior to claim submission.

Prior authorization determines whether the proposed service or treatment meets the definition of medical necessity under the applicable benefit plan. Prior authorization of a service is not a guarantee of payment of benefits. Payment of benefits is subject to several factors, including, but not limited to, eligibility at the time of service, payment of premiums/contributions, amounts allowable for services, supporting medical documentation, and other terms, conditions, limitations, and exclusions set forth in the member’s policy certificate and/or benefits booklet and or summary plan description. Regardless of any Prior authorization or benefit determination, the final decision regarding any treatment or service is between the patient and the health care provider.
