When and How to Get a Second Opinion

A second opinion refers to a fresh interpretation of a given diagnosis or treatment plan indicated by another doctor.

Getting a second opinion can increase your confidence in your diagnosis and treatment plans and ensure you choose a physician you have a comfortable rapport with. Some doctors also have access to emerging treatments through new clinical trials.

Second opinions can also uncover a potential misdiagnosis or find out that the proposed treatment may not follow current best evidence or is controversial. When faced with complex medical decisions, getting a second opinion can provide reassurance that you’re getting the proper care.

“No doctor should be upset if a patient asks for a second opinion,” says Loyola neurologist Jose Biller, MD. “A good and experienced healthcare professional should be comfortable in encouraging patients to consult with other specialists whenever appropriate.”

When to get a second opinion

There are many reasons to ask your doctor for a second opinion. Maybe you’re facing a life-altering diagnosis, such as cancer or an unusual neurological disorder. Or perhaps you and your doctor aren’t on the same page.

Either way, your full participation in the decision-making process is critical, says Dr. Biller. So don’t hesitate to make your wishes known.

Some specific reasons for considering a second opinion include:

• You disagree, don’t understand or are uncomfortable with your doctor’s diagnosis or treatment approach
• You have a serious or rare condition and want an expert or team of experts who specialize in that condition
• You’re considering surgery or have multiple treatment options to choose from
• Your current treatment is not effective or has potentially serious side effects
• Your doctor can’t find what’s wrong
• Your doctor says you don’t have any options

In some cases, you won’t even have to ask. Primary care providers and specialists often refer patients for another opinion to make sure their assessment is correct. Insurance companies may also require a second opinion before they approve treatment.

Don't delay getting a second opinion

You can get a second opinion at any time, but earlier is often better. If you don’t have a clear diagnosis, waiting will only delay the treatment you need.

For some health conditions, a delay could eliminate some treatment options or lead to disease progression. If you feel more comfortable with an online appointment, find out if a virtual second opinion is an option.

How do I find another doctor for a second opinion?

The best way to find another doctor for a second opinion is to ask your current doctor. Be open about the reasons for your request and ask for their help.

Your doctor should recommend a specialist who has a similar or higher level of expertise, says Dr. Biller. They may suggest an academic medical center that has a concentration of expertise and unique resources or focuses on specific areas of research.

Whenever possible, choose a specialist independent from your current provider so you rest assured you’ll receive an unbiased opinion.

How to prepare for your second opinion appointment

You’ll want the second doctor to have all your medical information to review prior to your appointment. Ask your current doctor to send all appropriate records, including office notes and test results. Before your appointment, check to make sure the second doctor received the records.

Also, find out what visit options are available, and determine if you prefer an in-person visit or a virtual second opinion appointment.

Dr. Biller advises patients to come to their second opinion appointment prepared. “It can be helpful to do some background research,” he says. “The more you know, the easier it will be to ask the right questions and get the information you need.”

Write down your questions before you go. If you’re not sure what to ask, start with these basic questions:

• Is my diagnosis correct or is there an alternative diagnosis?
• What is this condition and what is causing it?
• Do I need this surgery or will pharmacological intervention suffice?
• Are there other treatment options, including participation in clinical trials?
• What are the risks and benefits of my options?
• What is my outlook?

Before your appointment, find out if your insurance company covers second opinion visits. Also, check to make sure your new specialist accepts your insurance.

Next steps after getting a second opinion

An agreement between your doctors should make your decision easier, but the picture might not be that clear. You may receive a different diagnosis or alternative treatment options.

If your doctors disagree, the good news is you now have more information to consider. You may decide to:

• Bring the new information to your original doctor
• Transfer your care to the new specialist
• Try a third opinion

In many cases, your doctors can collaborate on your treatment. For example, patients with cancer often receive surgery or another type of treatment at a regional cancer center, then return home for ongoing chemotherapy.
