Full definition
Prior authorization is the process by which clinicians obtain approval from a health insurer before delivering specific services, procedures, or medications. Required for many higher-cost services — imaging, specialty drugs, elective procedures, certain durable medical equipment. Designed to control utilisation but creates significant operational burden — clinic staff time, delayed care, denied claims downstream of un-authorised services.
The burden has prompted regulatory reform. CMS Interoperability and Prior Authorization Final Rule (2024) requires payers to implement FHIR-based prior-authorization APIs by 2027 — submitting requests, returning decisions, real-time status — replacing fax and phone workflows.
For clinic technology: prior-authorization automation is a major operational lift. Modern platforms integrate with payer prior-auth APIs, capture clinical justification at point of order, route requests automatically, and track status. MOVO-X supports prior-authorization workflows for US clinic deployments.
Where prior authorization is used
- US specialty pharmacy
- Imaging (CT, MRI, PET)
- Elective surgical procedures
- Durable medical equipment
- Behavioural health
- High-cost specialty drugs
Types of prior authorization
Pharmacy prior-auth
Drug-specific approval — most common.
Medical prior-auth
Service or procedure approval.
DME prior-auth
Durable medical equipment.
Concurrent review
Approval during ongoing care (e.g. inpatient stay extension).
Retrospective review
Approval after care delivered — typically for emergency cases.
Quantified benefits
- ▸Utilisation management tool for payers
- ▸Stewards healthcare resources
- ▸Drives evidence-based-medicine adherence

Frequently asked
How long does prior-auth typically take?+
Highly variable — minutes for simple pharmacy auths; days to weeks for complex medical auths. CMS reform mandates faster turnaround.
Does MOVO-X automate prior-auth?+
Yes for US deployments. Integration with payer prior-auth APIs, clinical justification capture at point of order, automated routing and status tracking.
What's the FHIR-based prior-auth standard?+
Da Vinci Project profiles for prior authorization (CRD, DTR, PAS) — FHIR R4 implementation guides. CMS rule mandates these by 2027 for most payers.
Why is prior-auth controversial?+
Operational burden on clinics, care delays for patients, denial-rate variability across payers, lack of transparency in coverage criteria. Multi-stakeholder reform under way.
