Can my doctor help get a treatment covered by insurance?

Yes, and your doctor's involvement is often what turns a denial around. The National Cancer Institute says that when a plan will not cover a test or procedure your doctor thinks you need, you can ask them to write a letter explaining why it is needed, then send that letter to the insurer.

Insurers weigh a treating physician's clinical judgment more heavily than a patient's own account. That is not fair, but it is how the process works, so use it.

What makes the letter work

Ask for a letter of medical necessity, and ask that it be specific. A one-line note saying the patient needs this drug rarely moves anything.

Useful letters name your diagnosis and stage, list what you have already tried and how it failed or was not tolerated, state why this particular test or drug is the right next step for you, and cite the guideline or evidence that supports it. If a tumor biomarker result drove the decision, the letter should say which marker and quote the report.

Ask for a copy for your own file. If the case goes to external review months later, you will want it.

Doctor-to-doctor, and other moves your team can make

NCI suggests something many patients never think to request: ask your doctor to contact the medical director of your health plan. Insurers usually offer a physician-to-physician conversation, often called a peer-to-peer review, and a five-minute call can settle a case that letters could not.

Your doctor's office can also do the following.

• Handle prior authorization before treatment starts, so the denial never happens. Ask the office who does this and whether it has been submitted.
• Correct a coding problem. Denials are often about which code was billed, not about the medicine. Your billing department can tell you the exact code that was refused.
• Document why an off-label use fits. If a drug is approved for another cancer that carries the same biomarker as yours, the letter should say so plainly.
• File an appeal for you. You can appoint your doctor, or another medical professional who knows your condition, as your representative in an appeal or external review.

Getting help with clinical trial costs

If the disputed care is part of a clinical trial, the split matters. Patient care costs are the costs you would have had anyway, and health insurance often covers them. Research costs come from being in the trial, and the sponsor often covers those instead.

Ask the research coordinator whether other participants have had trouble getting routine care costs covered. If so, ask for help sending your plan an explanation of why this trial suits you. Medicaid covers all routine patient care costs in a clinical trial. With Medicare you may be reimbursed for some costs of trials testing new ways to diagnose or treat cancer.

What your doctor cannot do

Your doctor cannot overrule your plan, and cannot make a treatment covered that your policy excludes outright. Read your own policy for the appeal steps it sets out.

Your doctor also cannot chase the paperwork forever. Keep dated notes of every call, name, and reference number, and keep copies of everything you send. If the claim is denied again, the billing manager at the practice often knows the appeal route better than anyone else in the building.

This is educational information, not medical or legal advice. Your own care team and your plan documents are the authority on your situation.
