Provider Actions and Prior Authorization Workflow
Services and medications that require prior authorization
Prior authorization is required for all inpatient medical/surgical facility admissions (including acute care/hospital, hospice care, long term acute/sub-acute care, rehabilitation facility, and skilled nursing facility). It is also required for mental health and substance use disorder facility admissions (inpatient and residential treatment centers) and for the outpatient mental health services and outpatient specialty services listed in the policy (e.g., advanced imaging, cardiology, molecular genetic testing, musculoskeletal surgery and pain, radiation therapy, select outpatient surgeries, pain management, wound care). Specialty pharmacy medications covered under medical benefits and some pharmacy medications under the drug list also require prior authorization.
- Inpatient services: preauthorization required for all inpatient services (acute care, hospice, LTAC/sub-acute, rehabilitation, skilled nursing).
- Mental health/SUD admissions: inpatient and Residential Treatment Center (RTC) admissions require prior authorization.
- Outpatient specialties: advanced imaging, cardiology, molecular genetic testing, musculoskeletal (joint/spine surgery, pain), radiation therapy, select outpatient surgeries, pain management, wound care (see policy for full list).
- Specialty pharmacy: infusion site-of-care and provider-administered drug therapies (medical-benefit specialty pharmacy) require medical necessity review; some pharmacy drugs require prior authorization per the drug list.
Pharmacy prior authorization and possible step therapy
Some pharmacy medications require prior authorization under the Pharmacy Benefits (Prime); certain drugs may also be subject to step therapy per the plan’s drug list guide. Check the Prior Authorization/Step Therapy Program information and the drug list guide to determine if a specific medication requires prior authorization or step therapy.
- Prior Authorization is required on some medications before the drug will be covered — check the drug list guide.
- Refer to the Prior Authorization/Step Therapy Program information to determine step therapy requirements for FI and certain ASO groups.
Required clinical documentation with requests
All prior authorization requests must be accompanied by appropriate clinical/medical record information except for routine vaginal or cesarean section deliveries, which are exempt from that documentation requirement.
- Submit supporting clinical/medical records with the authorization request unless the request is for a routine vaginal or cesarean delivery.
- Providers may submit requests via Availity Authorizations & Referrals (see Provider Tools).
Denial risk from incomplete or ineligible requests
Failure to verify member eligibility and benefits first, or submitting a prior authorization request without the required clinical/medical record information, may result in denial.
- Complete an eligibility and benefits inquiry before submitting a prior authorization request to confirm coverage and whether prior authorization is required.
- Lack of required documentation or submitting requests for ineligible members can lead to denial of the request.
Background
Prior authorization is a pre-service medical necessity review used to determine whether a requested service or drug is medically necessary and covered under the member's health plan. It is not a guarantee of benefits or payment; providers should verify eligibility and benefits before submitting a request.
