Prior authorization made clear:

Understanding why prior authorization is a checkpoint for care and coverage

UnitedHealthcare is committed to ensuring our 50M members have access to safe, coordinated, effective care while helping make the health care system work better for everyone.1

Prior authorization is an important part of that commitment. This process helps to check whether medical care is safe, evidence-based and covered before it is administered. This helps protect members from unnecessary and potentially harmful care, as well as higher out-of-pocket costs. Importantly, most prior authorization requests are quickly approved.

While prior authorization is not needed before receiving care 98% of the time, it’s important to understand how it works, why it’s required in some cases — and what’s being done to improve the experience for both patients and providers.2

Our commitment to transparency

We know prior authorizations are an area of concern — and they are often misunderstood. We're publishing this information to help patients understand what prior authorizations are and how we use them to ensure patients get the best possible care.  We will continue to expand our transparency reporting in 2026 to include prior authorizations for prescription claims.

UnitedHealthcare is working to improve the prior authorization experience

Only 2% of our members’ claims required prior authorization.3 Of those prior authorizations submitted, 91.7% were approved.4

At UnitedHealthcare, we understand it’s not always clear how to work through getting approvals for prior authorizations. When a prior authorization is required, the process may seem complicated. That’s why we’re committed to simplifying the process and ensuring the best experience for our members.

We’re working to continually make this process easier, as part of our commitment to making the health care system work better for everyone. This supports our goal to help members get safe, high-quality care.

What is prior authorization and when is it needed?

Prior authorization is a process that may require your doctor to get approval from your health plan before providing a service. It’s an important checkpoint and is used to confirm services are covered by your health insurance plan, and that those services meet the standards for quality and safety. This review occurs before care is delivered and is never required for emergencies or urgent care. Nearly half of all prior authorizations are approved in real-time and almost all decisions are made within 24 hours.6 Let’s take a closer look at the numbers.

Frequently asked questions about prior authorization

Prior authorization is not a simple topic, so it’s natural that there may be more questions. Explore these answers to help learn about how prior authorization works and ways it’s being streamlined to improve the system overall.

UnitedHealthcare is taking steps to make the prior authorization process faster, simpler and more transparent by:

  • Signing on to 6 commitments to streamline, standardize and modernize the process across the industry, including reducing the number of services subject to prior authorization, accelerating response times, improving transparency and expanding real-time, electronic processes
  • Introducing a first-of-its-kind national Gold Card Program, which recognizes eligible physicians with a strong track record of evidence-based care by exempting them from certain requirements

Our work includes a continued focus on ways to improve, including: 

  • Ongoing efforts to regularly review and reduce the number of services requiring prior authorization
  • Advancing technology to speed up the process, reduce administrative burden and costs 
  • Increasing transparency throughout the claims process 
  • Reducing administrative problems that could impact approval 
  • Speeding up turnaround times 

Together, these efforts reflect our commitment to improving the experience for physicians and patients, while supporting safe, appropriate and affordable care. We know there is more work to do, and we will continue to pursue a process that better serves the people and providers who rely on it.

What’s the difference between a prior authorization and a claim? 

Prior authorization is a process that occurs before care is delivered. A claim is the portion of the bill that gets sent to the insurance company after care is provided.

If you visit a provider, and receive services or procedures, your provider will submit a medical claim to your health plan. 98% of medical claims did not require a prior authorization.12

UnitedHealthcare’s medical claims approval rate is 98%13

UnitedHealthcare approves 98% of claims for eligible members, when submitted in a timely manner with complete information, and after duplicate claims are removed. There are more details to know about this 98% approval rate, including:

  • We approve and pay 90% of claims shortly after they’re submitted
  • The remaining 10% go through an additional review process. This review checks for:

Eligibility

Some claims are submitted for patients that are not actually UnitedHealthcare members.

Duplicates

Occasionally, providers submit multiple claims for the same treatment or service.

Documentation

At times, the provider doesn’t submit all the information necessary to review a claim.

Clinical

Claims like these need additional review to ensure the care provided aligns with evidence-based clinical guidelines — this accounts for about 0.5% of all claims.

  • After this additional review is completed, the overall approval rate is 98%

While we stand by our 98% approval rate for medical claims, we know nothing is more personal than health care. That’s why we treat every claim we review with care and sensitivity, encouraging members to reach out to us if they have questions or need further assistance.
