Prior Authorization Requirements for Health Insurance Marketplace (2024)

For some services, utilization review is necessary to determine the medical necessity and appropriateness of a covered health care service for Superior HealthPlan’s managed care members.

Authorization Process, Procedures and Protocols

Please reference the sections below for additional prior authorization requirements and information.

Emergency And Post Stabilization Services

Physical and behavioral health emergencies, life threatening conditions and post-stabilization services do not require prior authorization.

These include non-elective, inpatient admissions, including those that are subsequent to emergency services and stabilization of the patient, which do not require prior authorization.

All inpatient confinements do require ‘notification’ of the admission no later than the next business day after the date of admission. Following notification of admission, concurrent and/or retrospective utilization review is conducted to confirm the continued medical necessity of the inpatient stay. Facility providers should referenceNotification of Admission and Concurrent Reviewsection on this webpage for additional details and information.

Professional services provided during a medically necessary inpatient admission do not require separate authorization.

Non-Preferred Provider Services

As an Exclusive Provider Benefit Plan (EPBP), Ambetter’s covered benefits do not include non-preferred provider services, with some exceptions. These include emergency services and medically necessary non-preferred provider services that are prior authorized.

Prior authorization is required before the provision of all non-emergent health-care services, supplies, equipment and Clinician Administered Drugs (CAD) delivered by a non-preferred provider.

It is the responsibility of the rendering, ordering or referring practitioner to initiate the request for prior authorization for non-emergency, non-preferred provider health-care services. Those requests will be reviewed to determine the medical necessity of approving the delivery of care outside of Ambetter’s preferred provider network, for those situations in which no preferred provider is available to deliver the applicable service. If a preferred provider is available for provision of the requested service, the prior authorization request may be denied with redirection to a preferred provider.

Timeframe For Requests

Requesting providers must initiate a request for prior authorization for non-urgent health-care services prior to delivering the requested service, medical supply equipment or Clinician Administered Drug (CAD).

It is recommended that prior authorization requests be submitted a minimum of5 business daysbefore the desired start date of service.
