Should I get a second opinion before surgery?
A surgeon's recommendation can feel like the end of the conversation. For an operation that isn't an emergency, there is usually time for another surgeon to look at the same file before you decide.

Should I get a second opinion before surgery?
It is worth considering when the operation is planned rather than urgent, and the decision about surgery stays with you. Medicare's booklet on second opinions says that if your doctor says you need surgery for a health problem that isn't an emergency, you can consider getting one. It also says it's up to you to decide when and if you'll have surgery, and that a second opinion can help you make a more informed decision. There are no hard-and-fast rules about when one is needed, the American College of Surgeons (ACS) says. Its patient page draws the line at confidence: if, after talking through your questions with your surgeon, you feel sure the operation is the best treatment, you probably don't need one. If you have doubts about whether it should be done, or the doctor recommending it is not a qualified surgeon, you may want one.
When can a second opinion help most?
When there is time to decide. AHRQ's booklet for people facing surgery says most operations are not emergencies and are considered elective, which means you have time to learn about the operation to be sure it is the best treatment for you. The same booklet calls a second opinion from another doctor a very good way to make sure the operation is the best choice. An emergency is different. Medicare's booklet says a second opinion is not something to wait for when you need emergency surgery. Some plans build a second opinion in. AHRQ's 2005 booklet says many health insurance plans ask for one before certain non-emergency operations, and that you may still ask for one if your plan does not require it. For Original Medicare, Medicare.gov says Part B covers a second opinion in some cases, for medically necessary, non-emergency surgery.
Will my surgeon mind if I ask?
A competent surgeon should not. ACS says consultation has always been part of good medical practice and that a competent physician should not be insulted if you decide to get further advice. AHRQ's booklet adds that your doctors should welcome questions. Asking does not commit you to switching. Medicare's booklet describes a second opinion as a right: to understand your treatment choices, to have another doctor look at them with you, and to take part in the decision. It also says a second or third opinion doesn't mean you have to change doctors, and that if you decide to have surgery, you choose who does it. AHRQ's booklet says you can also ask your primary care doctor for the name of another surgeon who could review your medical file.
How does a second opinion fit into the time before surgery?
It fits inside the time you have to decide, so that time is a fair first thing to ask about. No source says how long a second opinion should take or how long a planned operation can wait; a fair question for the first surgeon is how much time the decision can have, and what could change in the meantime. AHRQ's booklet frames the same idea as a question for your surgeon: what you will gain, or lose, by not having the operation now. It also describes watchful waiting, where you and your doctor check whether the problem gets better or worse over time, as one alternative to surgery. ACS lists "What will be the likely result if you don't have the operation?" among the questions to discuss before you agree to an operation. Records take time to move, too. Medicare's booklet suggests calling the second doctor's office before the visit to make sure your records have arrived.
Who should give the second opinion?
A surgeon with expertise in the operation you have been offered. ACS says to seek consultation from a qualified surgical specialist, and that a good way to judge qualifications is certification by a surgical board approved by the American Board of Medical Specialties. If you are unsure, your family doctor, your local or state medical society, the hospital where the surgeon practices or the surgical department of the nearest medical school should be able to tell you whether a surgeon is board-certified. For a name, Medicare's booklet points to your doctor or another doctor you trust.
What does the second surgeon need to see?
Your records and the results of tests you have already had, so the second surgeon is looking at the same file. AHRQ's booklet says getting your records from the first doctor means your tests do not have to be repeated. Medicare's booklet suggests asking the first doctor to send them ahead, and at the visit telling the second doctor what surgery was recommended and which tests you already had. The second surgeon may still want more. Medicare.gov says the second doctor may ask you to get additional tests as a result of the visit.
What could I ask the second surgeon?
The same core questions you asked the first, so the two answers can sit side by side. ACS's list of questions to discuss before agreeing to an operation covers the indications for it, other forms of treatment, the likely result without it, the risks, how it is expected to improve your health or quality of life, and whether there are likely to be residual effects. AHRQ's short list of questions adds a few you could borrow: why you need this treatment, whether there are alternatives, what the possible complications are, which hospital is best for your needs and how many times the surgeon has done this procedure. On experience, ACS's list for surgeons includes whether they perform the operation regularly, their success rate, how often patients have problems and which board certified them.
What if the two surgeons disagree?
Then you have more to weigh, and the decision is still yours. ACS says a second opinion is not necessarily better than a first one and that, whether the two agree or disagree, the final decision will be yours. Medicare's booklet lists two next steps you may want: talking more about your condition with your first doctor, or talking to a third doctor.
Can a family member help with a second opinion?
Yes, a family member or friend can come along. Medicare's booklet suggests asking one to go to the appointment with you and encouraging them to ask any questions they have. A friend or relative can help you talk with the doctor, AHRQ's booklet says. If you are helping a parent, a fair question to settle before the visit is who will tell the second doctor what surgery was recommended and which tests were already done, since Medicare's booklet lists both as things to tell the second doctor.
