Questions to Consider While Waiting for Insurance Approval

For some cancer patients, waiting for insurance approval is not simply an administrative step. It can affect when treatment begins.

Approval can take time, especially when prior authorization, network review, or additional documentation is required. During that period, patients and families feel unsure whether treatment can start as planned.

In the American Medical Association’s 2025 Prior Authorization Physician Survey, 95% of physicians reported that prior authorization delays access to medically necessary care.

A delay does not automatically mean that another treatment pathway is needed. But the clinical implications of waiting should be discussed with the treating physician.

Patients may wish to ask:

  • How long is it medically safe to wait?
  • Could a delay change the treatment plan or make the recommended treatment no longer an option?
  • What are the next steps if approval is not granted in time?

For some patients, waiting is clinically acceptable.

For others—particularly when the cancer is progressing, symptoms are worsening, or treatment eligibility could change—waiting longer may not be appropriate without further medical review.

Waiting is not always a neutral, it can influence the treatment timeline.

When approval is delayed, an international hospital review can help clarify whether another medically appropriate treatment option is available in time.
