When Your Insurer Stops Asking Permission: What Prior Authorization Cuts Mean for Seniors

In May 2026, UnitedHealthcare announced it was eliminating prior authorization requirements for roughly 30 percent of the services that previously required it — including certain outpatient surgeries, echocardiograms, and therapies. The announcement drew wide attention. It is worth noting upfront that this applies to UnitedHealthcare's plans specifically, affects different services depending on the plan and region, and does not automatically change requirements at other insurers. But to understand what it means even in those terms, you first have to understand what prior authorization is and how it has shaped the healthcare experience for older adults over the past decade.

What Prior Authorization Actually Is

Prior authorization — sometimes called "prior auth," "pre-authorization," or "pre-approval" — is a requirement by an insurance company that your doctor obtain approval before you receive a specific treatment, test, or prescription. It is not the same as a referral. A referral sends you to a specialist; prior authorization is an additional step on top of that, where the insurer reviews whether it agrees the procedure is medically necessary before agreeing to pay for it.

The process works like this: your doctor recommends a procedure or medication. If that item is on the insurer's list of things requiring prior auth, your doctor's office must submit a request — typically including medical records, notes, and a written justification — to the insurance company. The insurer then reviews it, sometimes within days, sometimes weeks, and issues an approval or denial. If denied, your doctor can appeal, but appeals take additional time and often require further documentation.

Prior authorization was originally designed to prevent unnecessary or potentially harmful procedures — surgeries performed without clinical indication, for example, or expensive brand-name drugs prescribed when an equally effective generic exists. Used appropriately, it serves a genuine purpose. Used broadly, it becomes a mechanism that delays care while adding significant administrative burden to medical practices and confusion and anxiety for patients.

How Common Is It?

According to the American Medical Association's annual prior authorization physician survey, the average physician practice completes approximately 45 prior authorization requests per physician per week. Nearly a third of physicians report that prior auth has led to a serious adverse event for a patient — meaning delayed care that resulted in a worsening condition, hospitalization, or worse. Fourteen percent reported that a patient experienced a permanent injury or disability as a result of a prior authorization delay. Three percent reported a patient death. These figures come from self-reported physician surveys rather than audited clinical records, so they should be understood as physicians' professional assessments of what they observed — not as independently verified outcome statistics. That said, the pattern they describe is consistent with concerns raised across oncology, cardiology, and other specialties that treat time-sensitive conditions.

These figures reflect conditions that are particularly consequential for older adults, who tend to need more procedures, more specialist visits, and more medications than younger patients — and for whom delays in care can compound quickly.

Which Senior Procedures Most Commonly Require Prior Authorization

The specific procedures that require prior authorization vary by insurer and plan. But certain categories come up with particular frequency for older adults, and understanding them is useful whether you are currently waiting on an approval or simply planning ahead.

Joint replacement surgery. Hip and knee replacements are among the most commonly performed elective surgeries in people over 60, and they require prior authorization under Medicare Advantage and most private insurance plans. Exceptions exist — some plan structures and provider arrangements handle it differently — but prior auth is the norm for the vast majority of beneficiaries. The insurer will typically want documentation of conservative treatment — physical therapy, injections, anti-inflammatory medication — before approving a replacement. This is intended to confirm the surgery is appropriate, but for patients who have already been living with severe joint pain and have tried those treatments, the documentation process can add weeks to an already difficult situation.

Cardiac procedures and imaging. Cardiac stress tests and catheterization commonly require prior authorization in Medicare Advantage plans. Echocardiograms are more variable — some plans require prior auth for them, others do not, and the answer can depend on the clinical setting and whether the ordering physician is in-network. That variability is part of why UnitedHealthcare's announcement specifically cited echocardiograms as one of the categories being removed from their requirements: it was a prior auth requirement that applied in some of their plans and is now being lifted. The broader point — that patients who most urgently need cardiac evaluation are the ones most affected by waiting periods — remains true regardless of which specific tests require approval at your plan.

Cancer treatment. Certain chemotherapy drugs, immunotherapy medications, and radiation therapy courses require prior authorization. For patients in active cancer treatment, the timing of these authorizations can affect the scheduling of entire treatment cycles. Oncologists and patient advocates have raised consistent concerns that authorization delays introduce gaps in therapy that may affect outcomes — though establishing clear causal links in individual cases is complicated, and research in this area continues. What is documented is that delays occur, that they create significant stress for patients and families, and that specialty oncology drugs — some of which cost tens of thousands of dollars per infusion — are among the most aggressively reviewed items on prior auth lists.

Skilled nursing and home health care. After a hospitalization, many patients are transferred to a skilled nursing facility (SNF) for rehabilitation before returning home. Others are discharged home with home health services — nursing visits, physical therapy, wound care. Both typically require prior authorization from Medicare Advantage plans. Critically, the insurer's review of whether a patient qualifies for these services can occur while the patient is still in the hospital, and a denial can affect whether and where they are discharged. HHS Office of Inspector General reports have documented that Medicare Advantage patients are statistically more likely to have SNF stays denied or cut short compared to patients on Original Medicare — this is a pattern in the data, not a guarantee in every case, but it is a well-documented difference between the two coverage types.

Durable medical equipment. Many categories of durable medical equipment — motorized wheelchairs, hospital beds, oxygen equipment, and CPAP machines, among others — require prior authorization under most Medicare Advantage plans, and certain high-cost DME also falls under targeted prior authorization programs in Original Medicare. Basic items like standard walkers or canes generally do not require prior auth. Getting a motorized wheelchair, for example, typically involves a physician visit, documentation of ambulation limitations, a home assessment, and a prior auth request — a process that can take months. During that time, the patient may be managing without equipment their doctor has already recommended.

Physical and occupational therapy. Therapy is commonly recommended after surgery, injury, or stroke, and it typically comes with session limits that require additional authorization to exceed. A patient recovering from a hip replacement may be approved for eight physical therapy visits initially; if they need more — which many do — their therapist must submit a new authorization request and wait. This introduces gaps and uncertainty into what should be a continuous recovery process.

Certain high-cost specialty medications. Drugs for rheumatoid arthritis, osteoporosis, macular degeneration, and certain cancers frequently require prior authorization and may also require "step therapy" — meaning the insurer requires the patient to try and fail on a less expensive drug before it will approve the one the doctor originally prescribed. Step therapy is particularly frustrating when a physician has a clear clinical reason for recommending a specific medication from the start.

What "Cutting Requirements by 30 Percent" Actually Means

When an insurer announces it is reducing prior authorization requirements, it means it is removing certain procedures and services from the list of things that require advance approval. If a procedure is no longer on that list, your doctor can order it and you can receive it without waiting for insurer sign-off.

There are a few important things to understand about what this kind of reduction does and does not mean.

It means faster access to the affected services. For procedures that are removed from the prior auth list, the practical experience changes significantly. Your doctor recommends the procedure, schedules it, and you receive it. There is no waiting period for an insurer to review and respond. For something like an echocardiogram ordered because your cardiologist hears something concerning, eliminating that waiting period has real value.

It means less administrative burden on your doctor — which benefits you indirectly. Medical practices spend enormous amounts of staff time on prior authorization paperwork and phone calls. When requirements are reduced, that time can be redirected. Physicians who spend fewer hours each week on authorization requests have more capacity for patient care. The benefit is indirect but meaningful over time.

The services being removed are generally those with high approval rates. Insurers do not tend to eliminate prior auth requirements for services they deny frequently. The procedures most likely to be cut from the list are those where the insurer was approving the vast majority of requests anyway — meaning the authorization requirement was generating friction without producing meaningful cost savings or clinical gatekeeping. The services that generate the most disputes and denials — complex surgeries, long-term therapy, specialty drugs — are less likely to be on the removed list.

It applies to one insurer's plans. A change by one company does not change the rules at other insurers. If you are enrolled in a Medicare Advantage plan run by a different company, or in a former employer's commercial health plan, your prior authorization requirements are governed by that insurer's policies. Changes at one insurer are worth noting as a sign of industry direction, but they do not change your individual situation unless your insurer follows.

Original Medicare does not use prior authorization in the same way. This is a meaningful distinction. Traditional Medicare (Parts A and B) does not require prior authorization for most services — your doctor can order an echocardiogram or refer you to a specialist and you receive care. Original Medicare does have limited prior authorization programs for certain categories, including some durable medical equipment and a small number of high-cost repetitive or scheduled services, but these cover a narrow slice of care compared to what Medicare Advantage plans require. Medicare Advantage plans are run by private insurers who set their own prior authorization lists within CMS guidelines, and those lists are substantially broader. If you are on Original Medicare, prior authorization is a much smaller part of your healthcare experience. If you are on Medicare Advantage, it is a much larger one.

What Is Driving These Changes

Prior authorization has been under increasing regulatory and legislative pressure. In January 2024, the Centers for Medicare and Medicaid Services finalized a rule requiring Medicare Advantage plans to respond to standard prior authorization requests within 7 calendar days and to urgent requests within 72 hours — tighter timelines than previously required. The rule also required plans to provide specific clinical reasons for any denial and to send authorization decisions directly to patients, not just to physicians.

Separately, Congress has been advancing the Improving Seniors' Timely Access to Care Act, which would establish additional prior authorization requirements for Medicare Advantage. Growing public attention to insurance denials — and a broader conversation about the relationship between insurers and the patients they cover — has also created pressure on major insurers to demonstrate responsiveness to these concerns.

When a large insurer announces a significant reduction in prior authorization requirements, it is happening in this context. The change is real and meaningful, but it is also taking place in a regulatory environment that was already moving in this direction.

What to Do If You Are Currently Waiting on a Prior Authorization

If you or a family member is waiting on approval for a procedure or medication, there are several things worth knowing:

• Ask your doctor's office for a status update. Authorization requests are managed by medical office staff, not by the physician directly. Ask specifically whether the request was submitted, when it was submitted, and whether the insurer has responded. Sometimes requests are delayed not by the insurer but by incomplete submissions or missing documentation.
• Request an expedited review if the situation is urgent. Insurers are required to have a process for expedited review when a delay would seriously jeopardize your health. Ask your doctor to document the clinical urgency and request expedited processing explicitly.
• Ask for a peer-to-peer review if you receive a denial. When a prior authorization is denied, your doctor has the right to speak directly with the insurer's reviewing physician — a process called peer-to-peer review. These conversations result in reversals more often than appeals alone. Ask your doctor's office to request one.
• File a formal appeal. Insurers are required to provide a denial reason and an appeal process. Keep a written record of all communications, dates, and the names of anyone you speak with. If your Medicare Advantage plan denies an appeal, you can request a review by an independent organization.
• Contact your State Health Insurance Assistance Program (SHIP). SHIP counselors are free and can help you navigate disputes with your Medicare plan. Find your local SHIP at shiphelp.org.

The Bottom Line

Prior authorization has been one of the most significant sources of friction between older adults and their healthcare in the Medicare Advantage era. Reductions in these requirements — when they apply to your plan and the specific services you need — translate directly into faster access to care and less stress navigating a system that can feel designed to slow you down.

The changes happening now are meaningful, but they are partial and uneven. Understanding what prior authorization is, which procedures are most affected by it, and what your rights are when you face a denial gives you the tools to navigate the system as it exists today — not as it ideally should be.
