On May 5, 2026, UnitedHealthcare announced that it will eliminate prior authorization requirements for approximately 30 percent of the services that currently require one, with the changes rolling out through the end of 2026. The company named the kinds of services affected: select outpatient surgeries, diagnostic tests such as echocardiograms, and certain outpatient therapies and chiropractic care. It described the move as the largest single reduction by a major insurer and said it would reach roughly 50 million members across its employer and Medicare Advantage plans.
Three weeks later, the code lists that would let a practice act on the announcement have not all appeared, and that gap is the reason for this article. We are in favor of fewer authorizations. We are also cautious, because every large change to a payer's authorization list produces a wave of denials in the three months that follow, and the denials come from the practice side as often as the payer side. Here is how to read the announcement and what to do about it.
Key takeaways
- The announcement gives a percentage and service categories, not a code list, and the effective dates run through December 2026 by line of business.
- UnitedHealthcare says authorization is now required for about 2 percent of medical services and that 92 percent of requests are approved within an average of 24 hours. Your denial log is the check on both.
- Do not stop requesting authorization for anything until you have the code, the plan type and the effective date in front of you.
- Expect CO-197 denials for 90 days after each effective date, and keep the payer's own list to appeal them.
- The removed services are usually the quick ones. Budget staffing on the list, not the press release.
What was announced, and what was not
The announcement gives a percentage of services and a set of categories, not a list of codes, and it gives a year-end target rather than a single effective date. In past reductions, UnitedHealthcare has published the affected codes by plan type (commercial, Medicare Advantage, community and state Medicaid plans, Exchange) on its provider site, with effective dates that differed by line of business and sometimes by state. Expect the same here. A 30 percent reduction in the number of services on the list does not mean a 30 percent reduction in the authorizations your practice submits; the services removed are typically the lower-volume, lower-cost items, while imaging, high-cost drugs and surgery stay.
The announcement also does not say anything about the authorization requirements for services that remain. Medical necessity criteria, site-of-service policies and notification requirements continue. Some services move from "authorization required" to "notification required," and a missed notification produces the same denial code as a missed authorization.
| What UnitedHealthcare said | What it means for a practice |
|---|---|
| 30 percent of services that still require authorization will no longer need it by the end of 2026 | Rolling effective dates by plan type; nothing changes until a code list with a date is posted |
| Select outpatient surgeries, echocardiograms and other diagnostic tests, some outpatient therapies and chiropractic care | Cardiology, orthopedics, physical therapy and chiropractic practices will see the most change; imaging and high-cost drugs are not named |
| Authorization now applies to about 2 percent of medical services; 92 percent approved within about 24 hours | Compare to your own log; if your approvals take a week, the gap is worth raising with your representative |
| Gold Card program for groups that follow evidence-based guidelines | Ask whether your group qualifies and what the criteria are for your specialty |
| Standardized electronic submission for 70 percent of authorizations by year-end | Ask your EHR or portal vendor what "standardized" means for your workflow |
| Rural provider exemptions expanding to about 1,500 hospitals by fall | Hospital-based; check whether your affiliated hospital is on the list |
The context
In June 2025, more than 50 health plans, including UnitedHealthcare, signed commitments coordinated by AHIP and the Blue Cross Blue Shield Association to reduce the scope of prior authorization by January 1, 2026, to honor existing authorizations for 90 days when a patient changes plans, to give clearer denial explanations, and, by January 1, 2027, to move to a standardized electronic authorization process with 80 percent of electronic approvals returned in real time. In April, AHIP reported that participating plans had removed about 11 percent of authorization requirements, or roughly 6.5 million requests a year. A 30 percent cut at the largest commercial insurer is, by any reading, a larger step than the pledge itself required.
Separately, the CMS interoperability and prior authorization rule has required Medicare Advantage and Medicaid managed care plans, since January 1, 2026, to decide standard requests within seven calendar days and expedited requests within 72 hours, and to give a specific reason for every denial. Those rules apply to UnitedHealthcare's government lines regardless of any voluntary announcement.
What to do when the code lists are published
- Download the list for each plan type you bill. Do not rely on the summary. Save the PDF with its publication date, because the list on the website will change again and you will need to prove what was in force on a date of service.
- Compare it to your authorization log. Pull every authorization your practice requested from UnitedHealthcare in the past 12 months, by CPT and HCPCS code. Mark which ones are on the new removed list. That is your workload reduction, and it is usually smaller than the headline.
- Do not stop requesting until the effective date, by line of business. A service removed from the commercial list on one date may remain on the Medicare Advantage list for months. Your authorization staff need a grid, not a memo.
- Update your scheduling and pre-visit checklists. If your front desk or surgery scheduler uses a "needs auth" flag by code, the flags must change on the effective date, not before and not after.
- Watch for CO-197 in the 90 days after each effective date. Payer systems lag their own announcements. A denial for a service that no longer requires authorization is appealable with the payer's own published list; see our note on denial management for how we build those appeals.
The mistake practices make
The mistake is the memo. Someone reads the news, sends an email that says "UHC is dropping prior auth on 30 percent of services," and two schedulers stop requesting authorizations for things that were never removed. Three months later the denials arrive, and the retro-authorization window has closed. Nothing changes in your workflow until you have the code list, the plan type and the effective date in front of you.
The second mistake is quieter. Practices that outsource authorizations to a vendor or a central scheduling team assume the vendor will catch the change. Ask them, in writing, how they track payer list versions and when they last updated the UnitedHealthcare rules. If the answer is a shrug, the denials will land on your remittances, not theirs.
A worked example
An orthopedic practice submits about 40 UnitedHealthcare authorizations a month: 14 for MRI, 9 for physical therapy beyond the visit limit, 8 for injections, 6 for surgery and 3 for durable medical equipment. Suppose the eventual list removes the therapy visits and some of the injections and outpatient procedures. The practice saves perhaps 12 requests a month, about 30 percent of its UnitedHealthcare volume, which happens to match the headline, and perhaps five staff hours. Useful. Not transformative. The MRI authorizations, which take the most time and produce the most denials, are not named in the announcement and are unlikely to move. Budget your staffing on the list, not the press release.
Now run the same exercise for the denials. If the practice received 20 CO-197 denials from UnitedHealthcare last quarter and 14 of them were on services that will come off the list, its denial volume falls. If most of the 20 were MRI, nothing changes, and the fix remains upstream at scheduling.
Questions we hear
Should we stop requesting authorizations now?
No. Nothing has an effective date for your codes until the code lists are published. Keep requesting as you do today.
If we request an authorization for a service that no longer needs one, does it hurt?
Usually the portal returns a message that no authorization is required; keep a screenshot with the date. That screenshot has won appeals when the claim system later denied for a missing authorization anyway.
Will other payers follow?
Several have announced smaller reductions since January under the AHIP commitments. In our experience the second and third payers move within a quarter of the first. Set a monthly task to check each payer's authorization list page, and record the version date each time.
What to do this month
- Pull 12 months of UnitedHealthcare authorization requests by code and plan type, so you can measure the change when the lists post.
- Pull last quarter's CO-197 denials from UnitedHealthcare by code.
- Assign one person to check the UnitedHealthcare provider site weekly for the code lists, and to save each version with its date.
- Ask your authorization vendor, in writing, how they track list versions.
- Draft the provider-by-plan-type grid the schedulers will use once dates are known, and tell them the memo is not coming.
