Can Insurance Deny Cancer Treatment?

A cancer diagnosis brings with it a complex emotional and physical journey. While a physician may recommend a specific course of treatment, health insurance companies frequently issue denials for cancer-related care. Receiving a denial letter can feel devastating, but it is not necessarily the final word on accessing the recommended care. Understanding the reasons behind these denials and knowing the steps available to challenge them are important for securing the necessary treatment. This article provides a guide to navigating the denial process, outlining your rights and the actions you can take to appeal the decision.

Primary Reasons Insurance Companies Deny Cancer Treatment

The foundation of most coverage denials is the insurer’s determination that the prescribed treatment does not meet their criteria for payment. A common reason cited is a lack of “medical necessity,” which means the insurance company’s internal guidelines do not align with the treating physician’s recommendation. Insurers maintain their own clinical standards and may decide that a less expensive or alternative treatment is sufficient, even if the oncologist believes otherwise. This often occurs when a treatment, such as a targeted drug or a specialized procedure, is considered outside the insurer’s established protocol for that stage or type of cancer.

Denials are also frequently issued for treatments classified as “Experimental” or “Investigational.” This classification often applies to therapies that are newly approved by the Food and Drug Administration (FDA) or those used “off-label,” meaning the drug is approved for one cancer type but is being used for another. Insurers may apply this label to treatments that have not yet been incorporated into their standard coverage policies, despite being accepted within the broader medical community.

Failure to obtain “Prior Authorization” or “Pre-certification” is a common reason for denial. Many high-cost cancer treatments, like specific chemotherapy regimens or specialized imaging scans, require the provider to get advance approval from the insurer. If the provider’s office fails to submit the request correctly, misses a deadline, or uses the wrong diagnostic code, the claim will be denied automatically on technical grounds. Receiving care from an “Out-of-Network” specialist or facility can also trigger a denial, as the insurer may refuse to cover non-emergency services provided outside their contracted network.

What to Do Immediately After Receiving a Denial

When a denial letter arrives, read the document thoroughly. This letter contains the specific reason for the denial, the deadline for filing an appeal, and the instructions for the appeal process. Note the exact language used by the insurer, whether it is “not medically necessary,” “experimental,” or a technical reason like a missing prior authorization.

After reviewing the denial, you must immediately contact your prescribing physician or oncology team and share the letter with them. Your medical team is equipped to understand the clinical rationale for the denial and will be the primary source of medical evidence for your appeal. They can review the denial for potential administrative errors, such as incorrect coding or missing information, which are sometimes the quickest denials to overturn.

Start gathering and organizing all relevant documentation. This includes the denial letter, medical records, test results, physician notes, and any correspondence with the insurance company. It is also important to keep a detailed log of all phone calls, noting the date, time, the name of the representative you spoke with, and a summary of the conversation.

Filing an Internal Appeal with Your Insurer

The internal appeal is the mandatory first step in challenging a denial. Most plans require the appeal to be submitted within 180 days of receiving the denial notice, but it is prudent to act quickly, especially with time-sensitive cancer treatment. The process involves presenting new evidence and a clear argument demonstrating why the treatment should be covered.

The core of the internal appeal submission is the clinical evidence provided by your physician. This typically includes a detailed letter of medical necessity from your oncologist, often citing specific medical literature, clinical guidelines, and peer-reviewed studies to support the treatment. This letter should explicitly connect the recommended treatment to your unique medical history and explain why alternative, covered treatments are not appropriate.

For urgent situations where delaying treatment could cause severe harm, the law provides for an expedited appeal process. This expedited review can often result in a decision within 72 hours. If the appeal is for a self-funded plan, which is regulated by the Employee Retirement Income Security Act (ERISA), the internal appeal is the only opportunity to create the official administrative record that a judge would review if the case ever reaches litigation.

Seeking External Review and Legal Options

If the internal appeal is unsuccessful, the next step is to request an External Review, which moves the decision-making process outside of the insurance company’s authority. This external review is conducted by an Independent Review Organization (IRO), a neutral third party composed of medical experts who have no financial ties to the insurer. The IRO reviews the entire administrative record, including all medical records and the insurer’s reasons for denial, and their decision is typically binding on the insurance company.

The right to an external review is mandated for most commercial health plans under the Affordable Care Act (ACA), and it is a powerful consumer protection. The IRO process specifically focuses on reviewing denials related to medical necessity or whether a treatment is considered experimental. You generally have four months from the date of the final internal denial to request this external review, and like the internal process, an expedited review is available for urgent cases.

The specific body regulating the external review depends on the type of plan you have: fully-insured plans are typically governed by state law, while self-funded employer plans fall under federal ERISA regulations. If both the internal and external reviews fail, the final recourse is to seek legal options, which involves consulting an attorney specializing in health insurance law. For self-funded ERISA plans, the legal challenge is based solely on the evidence presented during the internal appeal, underscoring the importance of building a strong case from the very beginning.
