If you’re on a Medicare Advantage plan, there’s one rule that can delay your care or leave you with a bill you didn’t expect: prior authorization.
Many people assume that if a doctor orders a test or treatment, their plan will automatically cover it. But in many cases, certain services require approval from your insurance provider first. If that step is missed, your claim could be denied—even if the care is necessary. Prior authorization is one of the most common reasons Medicare Advantage members run into coverage issues, and it’s often overlooked.
The good news is, with a few simple steps, you can avoid the most common pitfalls. Here’s what you need to know to stay ahead of the system and protect your care.
What Is Prior Authorization?
Prior authorization means your plan requires approval before you receive certain services. It’s a process some Medicare Advantage plans use to review whether certain services meet medical necessity guidelines before coverage is approved.
This approval may be required for:
- Imaging tests like MRIs or CT scans
- Outpatient procedures and surgeries
- Rehab services and physical therapy
- Medical equipment like CPAP machines or wheelchairs
- Certain medications
If your doctor orders something and no one requests prior authorization, your plan can deny the claim. It doesn’t matter if the care is needed or if it was recommended by your doctor—it won’t be covered unless the paperwork was submitted and approved first.
Why It’s a Common (and Costly) Misunderstanding
Many people assume if their doctor ordered it, it’s covered. But with Medicare Advantage, the approval step often falls through the cracks. Providers may forget, offices may delay, or no one realizes it was required until it’s too late.
That leaves you stuck. No appointment. No treatment. And a possible bill for something you thought was handled.
How to Protect Yourself
You don’t need to become an expert on insurance rules—but a few simple steps can help you avoid these problems:
Ask your doctor
When a test, scan, or referral is suggested, ask directly:
“Does this require prior authorization with my plan?”
Call your insurance provider
Look at your plan card and call the member services number. Confirm whether authorization is required and ask if it’s been submitted.
Keep a record
Save referral notes, documentation, and names of anyone you spoke to. If there’s a denial, you’ll want this information on hand.
Appeal if necessary
If your care is denied, don’t stop there. Many decisions are reversed once more details are submitted. Your doctor’s support can make a difference.
When Coverage Delays Turn Into Care Delays
Prior authorization can delay care that you and your doctor know is necessary. It’s not just about paperwork—it’s about your time, your health, and in some cases, your safety. According to the American Medical Association, one in three physicians has reported that prior authorization has led to a serious adverse event for a patient, including hospitalization, permanent impairment, or even death.
If you’re currently enrolled in a Medicare Advantage plan—or considering one—it’s essential to understand this risk. No one expects that in the middle of a health concern, they’ll have to wait on their insurance provider to approve care their doctor already recommended. But with Advantage plans, this happens more often than people realize. Being aware of it now can help you ask the right questions before urgent care becomes a frustrating waiting game.
