Radiation therapy prior authorization requirement

Affects UnitedHealthcare Preferred Care Partners and Preferred Care Network members in South Florida

Effective Jan. 1, 2024, UnitedHealthcare Medicare Advantage will require prior authorization for the following outpatient radiation therapies for UnitedHealthcare Preferred Care Partners and Preferred Care Network members:

  • Intensity-modulated radiation therapy (IMRT)
  • Proton beam therapy (PBT)
  • Stereotactic body radiation therapy (SBRT), including stereotactic radiosurgery (SRS)
  • Image-guided radiation therapy (IGRT)
  • Special and associated services (e.g., dosimetry and special physics consults)
  • Hypofractionation (fractionation) using IMRT, PBT and standard 2D/3D radiation therapy for prostate, breast, lung and bone metastasis cancers
  • Selective internal radiation therapy (SIRT), Yttrium 90 (Y90) and implantable beta-emitting microspheres for treatment of malignant tumors

Radiation therapy is part of the Cancer Guidance Program. This program can help you manage costs, improve outcomes and increase quality of care using evidence-based guidelines.

This program does not apply to Preferred Care Partners or Preferred Care Network members who have authorizations managed by WellMed. For those members, please use the delegate's process for notification and prior authorization on the Wellmed website under the Provider Resources tab.
