Utilization management is a collection of strategies used to support safe, evidence-based, and cost-effective medication use. In pharmacy benefits, utilization management may determine whether a medication is covered immediately, requires additional information, has a quantity limit, or requires a preferred treatment first. AMCP describes formulary and utilization management as collaborative processes designed to support appropriate, safe, and cost-effective medication use.1
Prior Authorization
Prior authorization requires additional review before selected medications are covered.
The request may evaluate:
- Diagnosis
- Treatment history
- Dose
- Age
- Laboratory results
- Disease severity
- Prescriber specialty
- Contraindications
- FDA-approved use
- Clinical guidelines
Prior authorization is also used to consider exceptions when a patient's needs are not adequately addressed by the standard formulary.
Step Therapy
Step therapy generally requires one or more preferred treatments before another medication is covered.
An exception may be considered when the preferred therapy:
- Was ineffective
- Caused an adverse effect
- Is contraindicated
- Interacts with another medication
- Is otherwise clinically inappropriate
Quantity Limits
A quantity limit restricts the amount covered during a defined period.
A plan may limit:
- Tablets per month
- Injections per year
- Inhalers per fill
- Grams of topical medication
- Daily dosage units
Limits may reflect FDA-approved dosing, safety concerns, product packaging, clinical evidence, or benefit design.
Formulary Management
A formulary is a list of medications selected for coverage.
Formulary management involves collaboration among pharmacists, physicians, other clinicians, and healthcare decision-makers.
AMCP defines formulary management as an integrated process intended to promote clinically appropriate, cost-effective medication therapy and positive outcomes.1
Drug Utilization Review
Drug utilization review may occur:
- Before dispensing
- At the point of sale
- After medication use
- Across a population
The review may identify:
- Drug interactions
- Duplicate therapy
- Excessive dosing
- Inappropriate duration
- Gaps in care
- Nonadherence
- High-risk medication use
- Opportunities for intervention
Who Develops Utilization-Management Criteria?
Criteria may be developed using:
- FDA labeling
- Clinical guidelines
- Peer-reviewed evidence
- Drug-safety information
- Comparative effectiveness
- Expert input
- Regulatory requirements
- Plan design
Pharmacists may draft, review, update, and operationalize these policies.
What Is the Role of the P&T Committee?
A pharmacy and therapeutics committee evaluates medications and formulary policies.
The committee may consider:
- Safety
- Effectiveness
- Place in therapy
- Comparative evidence
- Population needs
- Financial impact
- Monitoring requirements
- Access considerations
Cost matters, but a sound formulary process should not treat cost as the only clinical instrument in the orchestra.
Why Is Utilization Management Controversial?
Supporters argue that it promotes appropriate treatment, reduces unsafe or unnecessary use, and helps manage limited healthcare resources.
Critics point to administrative burden, treatment delays, unclear requirements, and barriers for patients and prescribers.
CMS has acknowledged these burdens and finalized the CMS Interoperability and Prior Authorization rule in 2024, requiring impacted payers to streamline prior authorization through electronic processes, shorter decision timeframes, and more specific denial reasons.2
What Does a Utilization-Management Pharmacist Do?
Responsibilities may include:
- Reviewing coverage requests
- Developing policies
- Evaluating new drugs
- Reviewing appeals
- Conducting utilization analyses
- Supporting audits
- Monitoring quality
- Educating staff
- Presenting to committees
- Collaborating with medical directors
The Bottom Line
Utilization management is not one barrier or one decision. It is a system of policies, evidence, technology, clinical review, and appeals that shapes how millions of patients access medications.
Frequently Asked Questions
What's the difference between prior authorization and step therapy?
Prior authorization requires additional clinical review before a medication is covered. Step therapy is a specific type of prior authorization that requires trying one or more preferred medications first before the plan covers the requested drug.
Is utilization management just about cutting costs?
No, though cost is a factor. AMCP describes formulary and utilization management as processes intended to promote appropriate, safe, and cost-effective medication use — a sound formulary process weighs safety, effectiveness, and population needs alongside cost.
Is prior authorization getting easier to navigate?
CMS finalized a 2024 rule requiring many payers to streamline prior authorization through electronic processes, shorter decision timeframes, and more specific denial explanations, with most requirements taking effect by 2026-2027.
What does a P&T committee actually do?
A pharmacy and therapeutics committee evaluates medications for formulary inclusion, weighing safety, effectiveness, comparative evidence, population needs, and financial impact — not cost alone.
Utilization management is not one barrier or one decision. It is a system of policies, evidence, technology, clinical review, and appeals that shapes how millions of patients access medications.
