APPENDICURE

A guide to fighting insurance denials and winning

When my husband David was first diagnosed with appendix cancer, we had sold our company and were on an inexpensive Blue Cross Blue Shield of North Carolina plan we could afford.

We had no idea what was coming….not just medically, but financially and administratively.

The disease itself was going to be the hardest thing we ever faced.

But the insurance system?
That was going to require an entirely different kind of fight.

I’m writing this because too many appendix cancer patients and caregivers are losing battles they didn’t even know they could fight. The insurance system is complicated by design, and rare cancer patients are especially vulnerable to that complexity.

So let me share what I’ve learned – the hard way 🙂

The Specialist Problem: Rare Cancers Don’t Fit the System

One of the first things I did after David’s diagnosis was go to the BCBS website to find a specialist. They have a tool where you enter your cancer type to find in-network oncologists.

I searched the list.

Appendix cancer wasn’t there.

That moment taught me something important: the system wasn’t built for rare cancers.

There are very few true appendix cancer specialists in the United States, and most work at large academic cancer centers such as:

• MD Anderson Cancer Center
• Memorial Sloan Kettering Cancer Center
• UC San Diego Moores Cancer Center
• Mercy Cancer Center
• City of Hope
• AHN

Patients often discover that the doctors most experienced in their disease are outside their insurance network.

So I did something unconventional: I found a way to contact the CEO of BCBS of North Carolina and explained the situation.

What happened next surprised me.

Because David had a rare cancer diagnosis, we were assigned a Concierge case manager – someone whose job was to help coordinate care and approvals for complex medical situations.

That level of support existed.

No one had told us about it.

What many patients don’t know

Most large insurers actually have:

• Complex case management programs
• Oncology case managers
• Rare disease support teams

But these programs are rarely offered proactively.

Patients often only get access after requesting them or after extremely expensive claims trigger internal review.

Many patients never discover these resources.

What you can do

• Call your insurance company and ask whether they offer complex case management or rare disease case management
• Request a dedicated case manager
• Ask about network adequacy exceptions or single-case agreements
• Document every call: date, time, representative name, and what was said
• Escalate if necessary

If your plan has no in-network doctor qualified to treat your condition, regulators may require insurers to allow out-of-network treatment at in-network cost levels.

The Prior Authorization Trap

Many cancer patients do not realize how dangerous prior authorization rules can be.

Insurance companies often require advance approval for:

• surgery
• chemotherapy
• specialty consultations
• imaging tests

If treatment occurs before authorization is formally approved, insurers may deny payment — even if the treatment was medically necessary.

Before the appointment, surgery or treatment takes place, ALWAYS confirm:

• authorization has been approved
• the approval number is documented
• the provider has the approval on file

before major treatment takes place.

When Insurance Approves and Then Denies Anyway

Here is where our story becomes painfully familiar to many cancer patients.

After we secured the concierge case manager and received approval for David’s first visit to MD Anderson, both the Concierge from BCBS confirmed that the rest of the year’s visits would be covered.

Then the claims were denied.

We filed two appeals with the North Carolina Department of Insurance.

We submitted documentation including:

• written approvals
• denial letters
• appeal records
• communication history
• Notes from David’s doctor explaining why he needed a specialist

Both were denied anyway.

Months later, out of the blue, the claims were approved with no explanation. We have since upgraded our insurance plan.

But the process took months of stress and hours of additional phone calls and paperwork during an already overwhelming time.

Studies show that a large percentage of insurance denials are overturned when patients pursue formal appeals, yet many patients never file one.

The HIPEC Problem: “Experimental” Isn’t a Medical Term

One of the most common insurance battles in the appendix cancer community involves CRS/HIPEC — cytoreductive surgery combined with heated intraperitoneal chemotherapy.

This procedure removes visible tumors and delivers chemotherapy directly into the abdomen.

For many appendiceal cancers, CRS/HIPEC is widely recognized and performed at major cancer centers.

Yet some patients are told the treatment is “experimental.”

Two things are important to know.

The FDA does not approve surgeries

The FDA regulates drugs, biologics, and medical devices.

It does not approve surgical procedures.

So when insurers deny surgery because it is “not FDA-approved,” that statement is misleading.

Insurance policies vary

Some insurers recognize CRS/HIPEC as medically necessary for certain appendiceal cancers, while others classify it as investigational depending on the situation.

This is why appeals citing clinical evidence and treatment guidelines matter.

Know Your Rights

Several protections exist for patients under federal and state law.

Off-label cancer treatment

Many states require insurance coverage for cancer treatments prescribed off-label when supported by recognized medical compendia such as NCCN guidelines.

Clinical trial protections

Federal law requires most insurers to cover routine patient care costs for people enrolled in approved clinical trials for life-threatening diseases.

Network adequacy

If no in-network physician can treat a rare disease, insurers may be required to allow out-of-network care at in-network cost levels.

Independent medical review

Patients can request an external review by physicians who are not employed by the insurer.

State insurance regulators

State Departments of Insurance investigate consumer complaints and can require insurers to reevaluate claims.

Important Warning About Employer Insurance

Many employer-sponsored health plans fall under ERISA, a federal law.

These plans are regulated differently than marketplace plans.

State insurance commissioners may have limited authority, and appeals may need to proceed through federal review processes instead.

Understanding which system governs your plan is critical.

Understanding Your Out-of-Pocket Maximum

Every health plan has a maximum out-of-pocket limit.

Once a patient reaches that amount, insurers must cover “covered services” at 100% for the rest of the plan year.

For patients anticipating major surgery or intensive treatment, scheduling care strategically within the same plan year can significantly reduce costs.

Centers of Excellent Departments

Some insurers maintain Centers of Excellence programs for rare or complex diseases.

These programs may allow treatment at specialized hospitals – even when those hospitals are normally outside the network.

Patients should ask whether their insurer offers this option.

Why This Shouldn’t Be Your Fight Alone

The most frustrating part of all of this is the energy it requires.

And energy is the one thing cancer patients and caregivers are already short on.

David’s treatment at MD Anderson was eventually approved.

But it required:

• direct outreach to insurer leadership
• assignment of a concierge case manager
• multiple appeals
• a state insurance complaint
• months of persistence

That story should not be the template.

It should be the warning.

We are working to push insurers to:

• recognize appendiceal cancer in provider search systems
• implement rare cancer case management as a standard benefit
• improve navigation for patients facing rare diseases

Until those changes happen:

Document everything.
Appeal every denial.
And don’t stop at the first wall.
