When you enroll in a Medicare Advantage plan, you’re trusting that your health care needs will be covered when it matters most. But what happens when the insurance company decides otherwise?
At MedicareSchool.com, we believe every Medicare beneficiary deserves clear, timely access to medically necessary care. Unfortunately, that’s not always the case with Advantage plans—particularly due to pre-authorization requirements that can delay or even deny vital procedures. In this post, we’re sharing five real-life stories from our own agents and clients that reveal just how serious the risks of prior authorization can be—and how you can avoid these outcomes.
What Is Pre-Authorization?
Pre-authorization (also known as prior authorization or pre-certification) is when an insurance company requires approval before certain medical procedures, hospital stays, or treatments can be provided.
This process allows insurers to decide whether a procedure is “medically necessary” before they agree to cover it.
Here’s the problem:
Pre-authorizations can cause delays, denials, and unexpected costs, even for time-sensitive or serious medical issues.
Medicare Advantage plans are private insurance plans that require pre-authorization for many services. By contrast, Original Medicare does not require prior authorization for most care. And when paired with a Medigap plan, your care is generally determined by you and your doctor, not the insurance company.
5 Real Situations Our Clients Faced With Denied or Delayed Coverage
Here are five situations we encountered in just the past year. These are not hypotheticals—they happened to real people on real Advantage plans.
1. Cardiac Stress Test Denied Without Active Symptoms
A client with a strong family history of heart disease was referred for a cardiac stress test. Despite the clear medical concern, the insurance company denied the procedure because the patient wasn’t experiencing symptoms at the time. The result? No proactive testing allowed. They were told to wait until they were symptomatic—essentially, until they were already in crisis.
2. Two-Week Hospital Stay Waiting for Approval
One client fractured a hip and was admitted to the hospital. They waited two full weeks for the insurance company to approve surgery. Not only did this delay their care and recovery, but the insurer also back-billed them for the hospital stay, calling it an “excessive” length of admission—even though it was caused by their own delay.
3. $20,000 Surprise Bill While Traveling
A client suffered a cardiac episode while traveling. The ER visit was approved, but once she was stabilized and moved to a hospital room, the insurer deemed her stay “non-emergency”—and refused to cover it. She received a $20,000 bill because she was now technically “out-of-network” and not in a qualifying emergency state.
4. Hours on the Operating Table Waiting for Approval
A woman was literally on the operating table, prepped for surgery, when the hospital was notified that prior authorization had not yet been approved. She waited for hours—sedated and prepped—while doctors escalated the request to higher-level administrators to get it cleared.
5. Ambulance Ride Denied as “Non-Emergent”
A man experienced alarming symptoms and called an ambulance. After being assessed, the insurance company retroactively determined the event didn’t qualify as an emergency. His claim was denied, and he was sent a $900 bill for the ride.
Why Do Prior Authorizations Happen?
Medicare Advantage plans are not run by Medicare itself. They’re administered by private insurance companies. These insurers are allowed to use pre-authorization as a cost-control tool, giving them the power to delay or deny coverage, even if your doctor deems the service necessary. The good news? Changes are coming.
In response to mounting concerns, the American Medical Association (AMA) conducted a 2023 survey revealing:
- 24% of physicians said prior authorization caused serious adverse events, including hospitalization, permanent harm, or death
- 78% said patients abandoned treatment due to insurance delays
As a result, the Centers for Medicare & Medicaid Services (CMS) issued new rules requiring:
- Electronic prior authorization systems by 2026
- 72-hour turnaround for urgent requests
- 7-day limit for standard decisions
- Clear explanations for denials
While this is a step in the right direction, it’s still years away—and it won’t eliminate the problem entirely.
The Safer Alternative: Medicare Supplement (Medigap) Plans
If you’re on a Medigap plan with Original Medicare, these kinds of delays and denials are extremely rare.
Here’s why:
- There are no prior authorizations required for most services
- Decisions are made between you and your doctor
- You may see any provider nationwide who accepts Medicare.
- Coverage is nationwide and portable
While Medigap plans may have a monthly premium, they often provide greater peace of mind, especially when health issues arise unexpectedly.
How to Make the Right Medicare Decision
Choosing between a Medicare Advantage plan and a Medigap plan isn’t just about cost. It’s about control.
- Do you want to manage fewer unknowns?
- Do you want access to any doctor or hospital that takes Medicare?
- Do you want decisions about your health made by your doctor, not a clerk at an insurance company?
If so, a Medigap plan may be the right choice.
