Important Reminders

  • If you don't have a required prior authorization before administering IMRT, SRS or SBRT services, your claim may be denied. Please remember that members can't be billed for claims that are denied because you didn't have prior authorization.
  • If you have questions about the member's benefits, please contact the care provider service phone number on the back of the member's ID card. For prior authorization questions, please call the UnitedHealthcare Clinical Request Line at 866-889-8054.
  • Having a prior authorization or pre-determination on file does not guarantee or authorize payment. Payment for covered services depends on the member's benefit plan and eligibility on the date of service, care provider eligibility for payment, claim processing requirements and the care provider participation agreement. Post-service determinations may still apply based on criteria published in medical policies as well as local and national coverage determination criteria. For these requirements, please see UnitedHealthcare Medicare Advantage Coverage Summaries.
