A big diagnosis or a plan for surgery can feel like a lot to take in. You may leave the appointment with a head full of new words and a heart full of questions. Many people in that spot wonder, “Should I get a second opinion?” It is a common and reasonable step. MedlinePlus says that having a second opinion is your right as a patient [1].
Asking for one does not mean you do not trust your doctor. It means you want to understand your choices and feel sure about the path ahead. This post walks through when one can help and how to ask without feeling awkward. It also covers how to check your coverage and what to bring.
One important note first. If you have urgent or emergency symptoms, get care right away. Getting another opinion should never delay emergency treatment. Call 911 in an emergency.
When a second opinion can help
There is no single rule for when to get one. Still, some situations make it worth a serious look. MedlinePlus, writing about cancer care, suggests thinking about one in these cases [1]:
- You have a rare condition, or your doctor has limited experience with it
- You have several treatment choices and feel unsure
- Your test results are unclear
- You got very different advice from different doctors
- You do not feel comfortable with the diagnosis or the plan
You can also get one after treatment has already started. Sometimes your own doctor may suggest one when the best approach is not clear [1].
Why does it matter? The National Cancer Institute says another opinion may give you more information and answer your questions. It can also give you a greater sense of control. It may also help you feel more confident that you have explored all your options [2]. For example, imagine you are told you need back surgery, but you have heard others say physical therapy helped them. Another opinion gives you a calm, safe way to ask, “Is surgery my best choice right now?”
How to ask without feeling awkward
Many people worry that asking will hurt their doctor’s feelings. In truth, asking for another opinion is a normal part of medical care. NCI says it is best to involve your doctor in the process [2]. One reason is practical. Your doctor’s office will need to make your records, like test results and x-rays, available to the second doctor [2].
Keep your words simple and friendly. You can say: “This is a big decision, and I’d like a second opinion before we move forward. Can you suggest someone?” If you feel nervous, write the sentence down and read it.
There are other ways to find a doctor too. MedlinePlus suggests asking another doctor you trust, or friends and family who have been through similar care [1]. For cancer, NCI offers a Find a Cancer Center page that lists NCI-designated cancer centers across the country. You can also call NCI’s Cancer Information Service at 1-800-4-CANCER (1-800-422-6237) for guidance [2]. Your health plan’s provider list is another good place to look.
Check second opinion coverage before you book
Cost is a real worry for many families, so it helps to check before you schedule. NCI notes that many health plans pay for a second opinion, and some require one, especially when a doctor recommends surgery [2]. Rules differ from plan to plan, so call the member services number on your insurance card. You can say: “Is a second opinion covered for me? Do I need a referral or prior approval? Is this doctor in my network?” Write down the name of the person you spoke with and the date.
If you have Original Medicare, Part B covers a second opinion for surgery that is medically necessary and not an emergency. Medicare also covers a third opinion if the first two are different [3]. After you meet the Part B deductible, you pay 20% of the Medicare-approved amount. The second doctor may ask for more tests, and Medicare covers those if they are medically necessary [3]. Your actual cost may depend on other insurance you have, what the doctor charges, and where you get care [3]. If you have a Medicare Advantage Plan, ask your plan about its own rules.
Gather your records
The second doctor can only help as much as the information they see. Federal privacy law protects your access to your records. With few exceptions, you have the right to see and get a copy of your medical and billing records [4]. A provider cannot refuse to give you a copy because you have not paid a bill. They may charge reasonable costs for copying and mailing. But they cannot charge you a fee for searching for or finding your records [4]. Many people find a patient portal is the fastest way to get test results.
MedlinePlus suggests bringing a few things. Bring your records (or confirm they were sent) and your scans on a disc or through a portal. Also bring a list of all your medicines, vitamins, and supplements, plus your first doctor’s diagnosis and plan [1]. Bring your written questions too. As MedlinePlus puts it, do not be afraid to ask them, because that is what the appointment is for [1]. A family member or friend can come along for support and help take notes.
Tru-Tips: Keep one folder, paper or digital, for this decision. Put your test results, scan discs, medicine list, and questions in it. Then call the second doctor’s office a few days before your visit and ask, “Did you receive my records and images?” It can save you from a wasted trip.
If the opinions differ
Sometimes the second doctor agrees with the first. That can help you feel more confident in your plan [1]. Other times, the advice is different. That can feel stressful, but it is useful information. You can talk over the differences with your first doctor and decide together whether to change the plan. You can get a third opinion to help choose. And you do not have to switch doctors. MedlinePlus says you get to decide which doctor will provide your treatment [1].
You can say to your first doctor: “The second doctor suggested a different approach. Can you help me understand why you each see it differently?” A good care team will welcome that conversation.
Let’s talk about it
Have you ever asked for a second opinion? What made it easier, or harder, to speak up? Share your experience in the comments. Your words might help someone else feel brave enough to ask.
One Tru Step: Log in to your patient portal or call your clinic today and request copies of your most recent test results, so they are ready if you decide to get a second opinion.
