This is my experience that I am sharing so you can use this knowledge to the extent it is relevant to your situation.
I have some exciting news to share with you.
This summer, my health insurance company denied my annual breast MRI. I appealed. They said no again. So, I appealed to the State of California. And this week, I got word that the denial was overturned!
If you've ever stared at a denial letter and felt that sinking, defeated feeling, I want you to read this. Because that first "no" is not always the last word. I want to walk you through exactly what I did, step-by-step, so you have a real roadmap if you ever need one.
Here's what's inside:
My full story (the frustrating parts and the win)
A step-by-step how-to for appealing a denial
The unexpected tool that made my case stronger
What Happened
Since 2005, I've received my cancer-related care at Stanford. It's where my team knows my history, knows me, and knows my complicated medical background. Due to radiation treatment I received at the age of 22, I have an increased risk for breast cancer. As a result, I get an annual breast MRI at a Stanford imaging site. My current insurer has covered it faithfully — except for two years when I had different insurance.
This year, something changed. My insurer decided the MRI wasn't "medically necessary" at Stanford and insisted I use a non-hospital imaging center instead. The thing that really got me upset is that they tried to pressure me over the phone - either agree in that moment to go to one particular provider, or they would deny coverage.
The other part that really got me going is that I don't have an HMO. The Stanford site is in-network. I have a high risk of breast cancer. Still, the denial came through.
It felt wrong. They were essentially pushing me toward lesser care than I'd relied on for nearly two decades. And I wasn't willing to accept that.
The Insurer’s “No” Is Not The Final Word
I want to plant this idea firmly before we get to the how-to.
A denial is often just the beginning of a conversation, not the end of one. Sometimes the insurer genuinely needs more information to approve something. And, sometimes it seems, they're just being cheap and hoping you won't push back.
Either way, you have the right to appeal. That right is not a favor — it's legally required for health plans. The details differ depending on your plan type (private insurance, Medicare, etc.), including where you send your appeal and what deadlines apply. But, a process exists, and your denial notice will spell out how to use it.
You do not need to hire outside help to appeal. I want to say that again for the person in the back: you can do this yourself.
How to Appeal a Health Insurance Denial, Step-by-Step
Let me break down the path I took. Definitely adjust the specifics to match your own plan. But, this structure will give you a strong starting point.
Step 1: Read the Denial Notice Carefully
Your denial letter is your instruction manual. It explains why you were denied and how to appeal, including the deadline. Don't skim it and toss it aside. Every detail here matters, and missing a deadline can cost you your chance to overturn the decision.
Step 2: Work with Your Healthcare Team for the First Appeal
Reach out to your doctor or specialist right away. They can provide medical records, detailed notes, or a letter of medical necessity to strengthen your case. Clear, professional documentation from your healthcare team adds weight to your appeal and directly addresses the insurer’s reasons for denial. Collaborating with them ensures your case is built on expert support, which can be pivotal in overturning the decision.
Here's some genuinely good news: your care team often does the heavy lifting at this stage. In my case, my Stanford team handled the first-level appeal directly with my insurance company. They submitted a letter explaining why the MRI at their facility was the appropriate standard of care for someone with my history.
However, in my case, that appeal was denied. Frustrating? Absolutely. But, this is exactly the moment most people give up, and it's precisely when you shouldn't.
Step 3: Escalate to an External Review
When the internal appeal failed, I took it to the California Department of Insurance for an independent medical review. This step was specific to my plan. Where you send your next level appeal will depend on your own coverage, but you are legally entitled to receive information about where to send it and what the timeline looks like.
This external step is where you usually step in personally. In my case, I needed to submit:
The letter my doctor had already sent to my insurer during the first appeal
A release for my relevant medical records
My own personal statement making the case
This is your voice on the record — and it carries real weight.
Step 4: Build Your Argument
I focused my statement on a few clear points that were hard to argue against:
Continuity of care: I've had this MRI at the same facility for roughly 18 years.
Precedent: My current insurer has covered it every single year (except for the 2 years I had different insurance)
Ongoing risk: My breast cancer risk hasn't magically diminished over the past year.
Complex history: My medical background makes it entirely appropriate to have superior technology and specialists at a university medical system rather than a run-of-the-mill imaging center.
Write down your version of these. What, if anything, makes your situation unique? Why does the care you're requesting genuinely fit your needs? Why might it be medically necessary? Facts and history are your friends here.
Step 5: Use AI to Sharpen Your Statement
This is the part that surprised me most. I took all my arguments and put them into Google Gemini, telling it I was appealing a health insurance denial to the California Department of Insurance. I prompted AI to help me draft an Independent Medical Review Statement.
Here's what that did for me:
It took a lot of the raw emotion out of my writing (understandable emotion — but not always persuasive to a reviewer).
It made my case more concise and organized.
It even provided citations showing this was the recognized medical standard of care.
I then looked up those references myself, confirmed them, and attached them to my statement. A little help from a tool at my fingertips made my argument dramatically stronger.
Step 6: Submit on Time and Wait
I sent everything within the allotted window. It was reviewed by an independent medical reviewer. And, within the timeframe, California informed me: the denial was overturned!
The Work Doesn't Stop at "Yes"
Winning felt wonderful, but there were still a few follow-up tasks. If you get your overturn, be ready to:
Reschedule the appointment (in my case, the MRI itself)
Recontact the prior authorization department at your healthcare provider so they resubmit to obtain authorization
Thank your doctor and care team — they're your allies, and, in my case, they handled the initial appeal
Yes, this was a lot of extra effort layered on top of everything else. But, I wasn't willing to accept lesser care simply because pushing back was inconvenient.
Common Pitfalls To Avoid
A few gentle reminders from someone who's been through it:
Don't give up after the first no. The first internal denial is often not the end.
Don't miss deadlines. They're firm, and they matter.
Don't do it all in one exhausted burst. Break it into small, manageable steps that respect your energy.
Don't go it entirely alone. Lean on your care team, and use every tool available to you.

You Have More Power Than the System Wants You to Believe
We all know health insurance can be one of the hardest parts of navigating chronic illness. It isn't fair that so much of the burden falls on us, especially when our energy is already spoken for. I feel that frustration deeply.
But, I hope my annoying experience gives you both knowledge and hope. You have real tools at your fingertips: your healthcare team, your tenacity, and a little help from AI. Sometimes the company just needs more information. Sometimes they're counting on you to walk away. Either way, you can appeal — and you can shape a strong case.
Hang in there. Your persistence matters more than you know.
