Utilization Management
Definition
Utilization Management
Utilization management is the set of review steps a health plan or a provider group uses to work out whether a requested service is appropriate, medically necessary, and given at the right level and in the right setting of care for that one patient.
Utilization management (UM) was initially referred to as utilization review (UR), and it remains a well-recognised part of a cost-management approach in health care service delivery and payment.
The reviews don’t sit at one point in the patient journey. UM interventions take place before, during, and after the clinical encounter — which is why the discipline is usually described by timing rather than by department.
That timing split matters for anyone staffing the function. A pre-service queue behaves nothing like an appeals queue, so the people, the turnaround expectations, and the documentation trail all differ.
Key takeaways
- UM decides whether a requested service is medically necessary and set at the right level of care.
- The three review types are defined by timing: prior authorization, concurrent review, and retrospective review.
- Reviews depend on physicians working closely with nurses and pharmacists.
- Good communication after a review improves patient outcomes, not just cost control.
- Non-clinical steps outsource cleanly; the clinical determination stays with licensed reviewers.
How it works
UM runs on criteria, not opinion. A reviewer compares the requested service against a set of criteria that determines appropriateness, using national standards of care where those exist, then routes anything ambiguous to a clinician for a judgement call.
The StatPearls chapter on utilization management by Angelo P. Giardino and Roopma Wadhwa, last updated 10 July 2023, sets out the three types by when they happen.
| Review type | When it happens | What it does |
|---|---|---|
| Prior authorization (“pre-auth”) | Before the clinical intervention is delivered | Puts a control in place ensuring the requested service or procedure is appropriate and delivered in an appropriate setting |
| Concurrent review | During clinical care for a patient admitted to a facility | Drives efficient, effective care, reduces misuse of inpatient services, and promotes high-quality, safe care during the stay |
| Retrospective review (“retro-review”) | After the clinical encounter | Looks back at care already delivered |
Prior authorization does more than gate spend. It can improve communication inside the organisation about patients being evaluated for specific conditions — which improves access and care coordination.
Concurrent review carries a similar double duty. It supports quality monitoring and care coordination around transitions, so the discharge hand-off isn’t the first time anyone reads the chart end to end.
None of this works as a solo act. Review decisions, denials and prior authorisations require physicians to work closely with nurses and pharmacists.
That interdisciplinary collaboration is the quality lever. Per the same chapter, good communication after UM reviews improves patient outcomes.
Documentation feeds every step. Reviewers pull clinical notes from the electronic health record, and clean medical coding decides whether a request is even readable at intake.
Examples
UM shows up in different shapes depending on who runs it. A commercial payer, a state Medicaid programme and a hospital’s own review team all apply the same three timing types, but their volumes, criteria sets and escalation paths look nothing alike.
Take an elective orthopaedic procedure. The surgeon’s office submits a pre-auth request, an intake coordinator checks the packet is complete, and a licensed nurse reviewer matches it against criteria before anything gets scheduled.
Now take an inpatient stay. Concurrent review runs while the patient is still admitted, checking each day that the level of care still fits, and flagging when a transition to a lower setting is clinically reasonable.
Public programmes carry their own layer. State Medicaid programmes publish their coverage and programme rules through Medicaid.gov, and the Centers for Medicare & Medicaid Services (CMS) runs care-delivery and payment models through the CMS Innovation Center.
Outsourced delivery follows the same split. Intake, document chase, status calls and letter generation are the parts that move cleanly to a healthcare call center or a shared-services team.
The clinical determination doesn’t move. It stays with licensed reviewers, which is why UM staffing plans separate the queue work from the judgement work before anything is offshored.
Appeals support behaves the same way. A virtual medical assistant can assemble the file, chase the missing note and track the clock, while the reviewer decides the outcome.
Related terms
UM sits inside a wider set of payer and provider functions that share the same records, the same coders and often the same staff. These neighbouring terms explain where a review starts, what it touches, and where the money lands afterwards.
- Prior Authorization: the pre-service review type that clears a procedure before it is delivered.
- Case Management: the longitudinal coordination of a patient’s care across settings and providers.
- Claims Processing: the downstream adjudication of a submitted claim after care has happened.
- Revenue Cycle Management (RCM): the end-to-end financial workflow from registration through final payment.
- Medical Billing: the preparation and submission of claims to payers for services rendered.
- Population Health: a group-level view of outcomes and cost that UM data feeds into.
FAQ
What is utilization management in simple terms?
It’s the review process a health plan or provider uses to decide whether a requested service is medically necessary and delivered at the right level and setting of care.
What’s the difference between utilization management and utilization review?
UM was initially referred to as utilization review, and the older term is still used for the review step itself. In practice most organisations now treat UM as the broader function covering all three timing types.
What are the three types of utilization management?
Prior authorization happens before the clinical intervention, concurrent review happens during an inpatient stay, and retrospective review happens after the clinical encounter. Each one asks the same appropriateness question at a different moment.
Who actually makes a utilization management decision?
Decisions, denials and prior authorisations require physicians to work closely with nurses and pharmacists, so the determination sits with licensed clinical staff rather than administrative reviewers.
Can utilization management be outsourced?
The non-clinical steps — intake, document chase, status calls and letter generation — outsource cleanly, while the clinical determination stays with licensed reviewers.
Providers building or scaling clinical review capacity can compare offshore delivery partners through the Outsource Accelerator hubs.
