Medicare covers second opinions, but the rules depend on whether your doctor or Medicare initiates the request

Yes, Medicare pays for a second opinion in most situations. If your doctor refers you to another doctor for a second opinion about your diagnosis or treatment plan, Medicare Part B covers the visit and any tests that doctor orders. You pay your normal coinsurance (usually 20% after you meet your deductible). The second opinion doctor does not have to be in your current doctor's office or practice — you can see any doctor who accepts Medicare.

The coverage is straightforward when your own doctor suggests it. The situation is different if you want a second opinion but your doctor has not referred you. Medicare still covers it, but you will need to understand how the payment works and what to expect from the second opinion doctor's office.

Key Takeaways

  • Medicare Part B covers second opinion visits and related tests when referred by your doctor, and you pay your normal 20% coinsurance after meeting your deductible.
  • You can seek a second opinion on your own without a referral, and Medicare will still cover it, but the second opinion doctor's office may bill you upfront until they verify your Medicare coverage.
  • For surgery, Medicare covers a second opinion before the procedure and sometimes a third opinion if the first two disagree.
  • Your second opinion doctor can be any physician who accepts Medicare — they do not need to be affiliated with your current doctor or practice.
  • Some Medicare Advantage plans have different rules about second opinions, so check your plan documents or call your plan before scheduling.

How Medicare pays when your doctor refers you

When your primary care doctor or specialist refers you to another doctor for a second opinion, the referral itself does not determine whether Medicare pays — Medicare pays based on whether the second opinion visit is medically necessary. Your doctor's referral is usually strong evidence that it is necessary, so the second opinion doctor's office will typically accept it and bill Medicare directly.

You will owe your normal coinsurance, which is 20% of the Medicare-approved amount for that visit and any tests ordered. If you have not met your Part B deductible for the year, you will pay that first. The second opinion doctor does not need special permission from Medicare or your primary care doctor to see you — a referral is a courtesy, not a requirement.

Seeking a second opinion without a referral

You have the right to see another doctor for a second opinion even if your current doctor has not suggested it. Medicare will cover that visit, but the process is slightly different. The second opinion doctor's office may ask you to pay upfront or may contact Medicare to verify coverage before the appointment. This happens because without a referral, the office cannot assume Medicare will cover the visit until they confirm it with Medicare directly.

To avoid surprises, call the second opinion doctor's office before your appointment and tell them you are a Medicare patient seeking a second opinion. Ask whether they will bill Medicare directly or whether you should expect to pay at the time of service. Bring your Medicare card and any medical records from your current doctor — the second opinion doctor will need your test results, imaging, and diagnosis to give you a meaningful opinion.

Second opinions before surgery

Medicare has specific rules for second opinions before surgery. If your doctor recommends surgery, you can see another surgeon for a second opinion at no cost beyond your normal coinsurance. Medicare covers this visit and any tests the second surgeon orders. Many people find this reassuring before a major procedure, and Medicare recognizes that value.

If the first two surgeons disagree about whether you need surgery, Medicare will cover a third opinion. This rule applies only to surgery — not to medical management or other treatments. The third opinion must come from a different surgeon than the first two, and Medicare will cover it the same way as the first two opinions.

What Medicare Advantage plans cover for second opinions

If you have a Medicare Advantage plan (Part C), your coverage for second opinions may differ from Original Medicare. Some plans require you to use doctors within their network, which may limit which doctors you can see for a second opinion. Other plans may require a referral from your primary care doctor before they will cover a second opinion visit.

Check your plan's member handbook or call your plan's customer service line before scheduling a second opinion. Your plan can tell you whether the second opinion doctor is in-network, whether you need a referral, and what you will owe out of pocket. If the second opinion doctor is out-of-network, your plan may cover less or not at all, depending on your specific plan rules.

Getting your medical records for the second opinion

The second opinion doctor needs your medical records to give you a useful opinion. This includes your diagnosis, test results, imaging (X-rays, CT scans, MRI), pathology reports if a biopsy was done, and your current medications. Request these records from your current doctor's office — they are required by law to provide them, usually within 10 business days.

You can ask your current doctor's office to send the records directly to the second opinion doctor, or you can pick them up and bring them yourself. If you are seeing the second opinion doctor soon, calling your current doctor's office to request expedited records can help. Many offices will send records electronically if the second opinion doctor's office requests them directly.

When to seek a second opinion

A second opinion makes sense in several situations: before major surgery, when you have been diagnosed with a serious condition like cancer, when recommended treatments carry significant risks or side effects, when you are unsure about your diagnosis, or when you straightforward feel uncertain about your doctor's recommendation. You do not need your doctor's permission or approval to seek a second opinion, and most doctors expect patients to do this for major decisions.

Some people worry that asking for a second opinion will offend their doctor. In reality, most physicians understand that patients want to be thorough about important health decisions. If your doctor reacts negatively to a second opinion request, that itself may be useful information about whether you feel comfortable with that doctor long-term.

Frequently Asked Questions

Do I need my doctor's permission to get a second opinion?

No. You can see another doctor for a second opinion without asking your current doctor. However, you will need your medical records from your current doctor, so you will need to request those. A referral from your doctor is helpful but not required for Medicare to cover the visit.

Will my doctor know I got a second opinion?

Not unless you tell them or the second opinion doctor sends a report to your current doctor. The second opinion doctor may offer to send a summary of their findings to your primary care doctor if you ask. Some patients choose to share the second opinion with their doctor; others do not.

What if the second opinion doctor disagrees with my current doctor?

Disagreement between doctors is not uncommon, especially for complex conditions. You may want to discuss both opinions with each doctor, ask them to explain their reasoning, or seek a third opinion. Medicare will cover a third opinion in some situations, particularly before surgery.

Does Medicare cover a second opinion for mental health or therapy?

Yes. If your psychiatrist or therapist recommends treatment and you want a second opinion from another mental health provider, Medicare Part B covers that visit. You pay your normal 20% coinsurance. The second opinion provider must accept Medicare.

What if I have a Medicare Advantage plan instead of Original Medicare?

Your plan may have different rules about second opinions, including network requirements or referral requirements. Call your plan before scheduling to confirm coverage. Some plans cover second opinions the same way Original Medicare does; others have stricter rules.
