Getting a second opinion on treatment — when and how

Reviewed by a board-certified geriatric medicine specialist

A second opinion is not an insult to your parent's doctor. It is standard medical practice, especially for serious diagnoses and major treatment decisions. Studies published in the Journal of Clinical Oncology found that second opinions changed the diagnosis or treatment plan in 10 to 60 percent of cases depending on the condition. Medicare covers second opinions, and good doctors expect them.

Second Opinions Change Diagnoses or Treatment Plans in a Significant Percentage of Cases, and Seeking One Is a Normal Part of Responsible Medical Care

There's hesitation that many adult children feel when thinking about asking for a second opinion about a parent's treatment. What if it offends the doctor? What if the doctor thinks you don't trust them? What if it complicates the relationship? These worries are understandable, but they shouldn't prevent you from getting a second opinion when something feels off.

Good doctors expect patients to seek second opinions. They understand it's reasonable to want confirmation about major medical decisions. They know that another perspective sometimes clarifies thinking. They're not threatened by this. The doctors who do feel threatened may be the ones you should be least inclined to trust without additional opinions.

The question of when to seek a second opinion deserves consideration. Some situations make it obvious. If your parent has been diagnosed with cancer and is being recommended chemotherapy, a second opinion is standard practice. The National Cancer Institute recommends it. If they're being told they need major surgery, getting confirmation makes sense. If they're being started on a medication class with significant side effect risk, another perspective helps.

But second opinions aren't just for major diagnoses. If you're confused about a treatment recommendation, that's reason enough. If your parent isn't improving on the recommended treatment, that's reason to seek another view. If something just doesn't feel right, that instinct matters.

Starting the conversation with your parent's doctor is usually the right first step. Say something straightforward: "I'd like to get a second opinion on this treatment recommendation. Can you help me understand where to go for that?" Most doctors will accept this request and may offer recommendations of specialists they respect.

Asking your doctor for a referral has advantages. They know good specialists. They know who may offer differing perspectives. They can send your medical records directly to the second opinion doctor, ensuring nothing gets lost. They maintain professional relationships that help communication. Using their referral is often the easiest path.

If your parent has Medicare, second opinions are covered. Medicare Part B pays for second opinions on whether surgery or a specific treatment is medically necessary, and it covers a third opinion if the first two disagree. Check with your parent's specific plan about any referral requirements. Some Medicare Advantage plans require referrals for specialist consultations while Original Medicare does not.

Finding the right doctor for a second opinion depends on the condition. For cancer, you might seek a second opinion at an NCI-designated cancer center. For heart disease, you might go to a university hospital or specialized cardiac center. For less common conditions, you may need to look beyond your local area. Your parent's doctor can guide you toward appropriate specialists, and many academic medical centers now offer remote second opinions where they review records and imaging without requiring an in-person visit.

There's also the question of how much information to share with the first doctor. Some people worry that telling the first doctor about seeking a second opinion will bias their care. This isn't a reasonable concern in most cases, but the worry exists. Usually, you can simply mention that you're seeking a second opinion without naming the consultant. The first doctor doesn't need to know every detail.

The second opinion process usually involves a consultation. The second opinion doctor reviews your parent's medical records and history. They may do their own exams or tests. They talk through the diagnosis and treatment options. They offer their perspective on what they'd recommend. This may confirm the first opinion, suggest alternatives, or recommend something different entirely.

An important point is that a second opinion isn't binding. It's information your parent can use to make decisions. Maybe the two doctors agree, which is reassuring. Maybe they disagree, and a third opinion becomes necessary. Maybe they offer different approaches, all of which are reasonable, and your parent gets to choose among them.

When two doctors offer different recommendations, it's worth understanding why. Sometimes it's because they specialize in different approaches. A surgeon may recommend surgery while an internist recommends medication. Both may be reasonable, and it's your parent's choice which direction to pursue. Sometimes it's because one doctor has more current information or deeper expertise in the specific condition. This is why getting expert opinions is important.

The cost of a second opinion varies. Medicare covers it. Most private insurance covers it with a copay or deductible. If cost is a concern, ask about it upfront. Some hospitals offer reduced rates for second opinion consultations, and some academic medical centers have formal second opinion programs with set fees.

The timing of a second opinion matters when treatment is urgent. For many conditions, waiting a week or two for a second opinion doesn't change outcomes. For some conditions, delaying treatment could be harmful. Discuss with both your parent's doctor and the second opinion doctor what timeline is safe. In emergencies, treatment comes first and second opinions come after.

The records needed for a second opinion should be thorough. Medical records, lab results, imaging studies, previous treatment records, medication lists, allergy information: all of this helps the second opinion doctor make an informed assessment. Ask your first doctor's office to send everything, or prepare a packet of records to bring to the second opinion appointment.

Your role in seeking a second opinion depends on your parent's capacity and preference. Some older adults want to handle this themselves and just need your support and encouragement. Some need you to do the legwork of finding a doctor, scheduling, gathering records, and attending the appointment. Some need you to take notes during the consultation because they won't remember details. Adjust your involvement to match your parent's needs.

Sometimes your parent resists a second opinion. They trust their doctor and don't want to question their judgment. They're tired and don't want more appointments. They're anxious about whether another doctor might say something worse. These are legitimate feelings worth addressing. Sometimes sitting with that resistance and exploring where it comes from helps. Sometimes you need to gently but firmly advocate for a second opinion despite their reluctance, especially when the stakes are high.

After the second opinion, you may need to help synthesize the information. If both doctors agree, that's reassuring. If they disagree, you may need to help your parent think through the different recommendations. What are the tradeoffs? What are your parent's values? What does your parent actually want? The doctors provide information. Your parent gets to decide.

Good medical care includes multiple perspectives. You're not being disloyal to your parent's primary doctor by seeking a second opinion. You're being thorough.

Frequently Asked Questions

Will my parent's doctor be offended if we ask for a second opinion?
Good doctors welcome second opinions because they know confirmation builds patient confidence and catches occasional errors. The American Medical Association considers seeking second opinions a standard patient right. If a doctor reacts negatively to the request, that reaction itself is useful information about how they approach patient care.

Does Medicare pay for second opinions?
Yes. Medicare Part B covers second opinions on whether surgery or a major treatment is medically necessary, paying 80 percent of the approved amount after the deductible. If the second opinion disagrees with the first, Medicare also covers a third opinion. Medicare Advantage plans generally cover second opinions too, though they may require a referral.

How do I get my parent's medical records sent to the second opinion doctor?
Ask your parent's doctor's office to send records directly, or request copies under HIPAA (you have the right to your own medical records within 30 days). Most offices will fax or electronically transfer records to another provider with a signed release. Imaging studies like MRIs and CT scans can be sent on disc or through secure electronic transfer. Give the second opinion office a heads-up about what's coming.

What if the two doctors disagree on the diagnosis or treatment plan?
This happens more often than people expect. Ask each doctor to explain their reasoning. A third opinion from a different specialist or academic medical center can help break the tie. Focus on understanding the tradeoffs of each approach and which one aligns with your parent's values and priorities. The decision ultimately belongs to your parent.

Can we get a second opinion from a doctor in another state without traveling?
Yes. Many academic medical centers and major hospitals now offer remote second opinions, where specialists review records, imaging, and pathology slides and provide a written assessment. This is especially useful for complex cases where expertise may not be available locally. Ask the second opinion center about their telehealth or remote review options.
