Even Celebrities Get Their Doctor-Ordered Scans Denied By Insurance: Here’s How To Fight Back In 2026

Most patients never appeal a denied scan but 50% of peer-to-peer reviews overturn denials. Here’s how to use the system in 2026.

When actress Christy Carlson Romano, best known for playing Ren Stevens on the Disney Channel series “Even Stevens” and for voicing the title character in the animated series “Kim Possible”, told her Instagram followers in February 2026 that her cancer screening came back “not negative” and her insurer wouldn’t cover the PET scan her doctor ordered next, thousands of patients responded with versions of the same story.

Romano struggled to get her insurance to cover it, and the frustration was immediate and familiar: doctor recommends a test, insurer says no, patient is left holding a denial letter and a four-figure out-of-pocket estimate.

If you like to stay ahead of problems before they arrive, this is worth understanding. The denial pattern is documented, the appeal odds are better than most people realize, and a federal rule that took effect this year has shortened the timeline insurers can drag things out.

The Denial Pattern Is Real and the Price Tag Is Steep

PET scans run $3,000 to $6,000 at hospital outpatient departments and $1,500 to $2,800 at freestanding imaging centers, according to BillKarma’s 2026 analysis of claims across more than 4,800 hospitals. That same analysis found 34% of PET scan prior authorization requests are initially denied by commercial insurers, one of the highest denial rates of any imaging modality.

The most common reasons are mundane and often fixable: no prior authorization on file, the insurer’s medical necessity criteria weren’t met, an out-of-network facility or a CPT billing code mismatch between what was authorized and what was actually billed. A single-digit difference in a code can trigger a denial.

What Changed for Patients on January 1, 2026

The CMS final rule (CMS-0057-F) that took effect January 1, 2026, requires insurers to respond to standard prior authorization requests within 7 calendar days and urgent requests within 72 hours, down from 14 days, per HealthBillCentral’s 2026 prior authorization guide.

You have 180 days from your denial notice to file an internal appeal, per HealthCare.gov. And starting March 31, 2026, Medicare Advantage, Medicaid and ACA marketplace insurers are required to publicly post their prior authorization approval rates, denial rates and appeal outcomes, which means you can actually compare how aggressively different plans deny before you enroll.

The Step-by-Step Appeal Playbook

  • Read the denial letter for the reason code. CO-197 means lack of prior authorization. CO-50 means not medically necessary. The code tells you exactly what you’re dealing with and dictates your next move.
  • Check the CPT code first. Ask your doctor’s office to confirm the correct code was submitted. A coding error can often be corrected and resubmitted without a formal appeal, which is the fastest path by far.
  • Request a peer-to-peer review. This is where your ordering physician speaks directly with the insurer’s medical director. Muni Health’s 2026 prior authorization denial guide reports more than 50% of denials are overturned at this stage. Most patients never ask for it.
  • File a formal internal appeal. Bundle your denial letter, physician notes, prior test results and a letter of medical necessity. HealthCare.gov confirms internal appeals must be decided within 30 days for services not yet received.
  • Request an external review if the internal appeal fails. An independent reviewer takes over the decision. Per KFF’s March 2026 analysis, nearly half of external review decisions overturn the original denial.
  • Contact your state Department of Insurance if timelines are violated or the process stalls without explanation.

The appeal system rewards patients who keep going. A denial letter isn’t a final answer, and in 2026 the rules give you more tools to push back than at any point in recent years.
