Does insurance cover cancer second opinions?

Short answer: yes, most insurance covers cancer second opinions, but the rules differ by plan type. Medicare pays. Commercial plans almost always pay. What varies is whether you need a referral, whether the provider must be in-network, and how virtual second opinions are treated.

Original Medicare (Parts A and B)

Medicare covers second opinions for medical and surgical decisions, including cancer treatment. You pay the standard Part B deductible and 20% coinsurance (Medigap usually covers the coinsurance).

You do not need a referral under Original Medicare. You can go directly to any doctor who accepts Medicare. For cancer second opinions at major centers, all NCI-designated cancer centers accept Medicare.

Per Medicare.gov, Medicare will also cover a third opinion if the first and second opinions disagree.

Medicare Advantage

Medicare Advantage plans are required to cover the same services as Original Medicare, but the network rules differ. Most Medicare Advantage plans:

• Allow second opinions within their network without referral
• May require prior authorization for out-of-network second opinions
• Cap total annual in-network out-of-pocket at $8,850 for 2024, a meaningful protection for cancer patients

Call the plan’s member services and ask: “I want a second opinion at [center name]. Is that provider in-network? Do I need prior authorization?”

Some Medicare Advantage plans have specific second-opinion benefits beyond what Original Medicare provides (some include expert second-opinion networks).

Commercial PPO

PPO plans let you see any provider, in-network or out-of-network, with higher cost-sharing for out-of-network. Second opinions are generally covered:

• In-network: subject to copay or coinsurance per your plan
• Out-of-network: covered but you pay more; annual out-of-pocket max still caps your exposure

You generally don’t need a referral under a PPO. Verify with member services if you want to be certain.

Commercial HMO

HMO plans require in-network providers and often a PCP referral for specialist visits. For a cancer second opinion:

1. Call your PCP or in-network oncologist and request a referral.
2. Ask member services: “Is [second-opinion center] in my network? If not, can I request an out-of-network exception?”
3. If they’re out-of-network, HMO plans will often authorize an exception for a cancer second opinion, especially when in-network expertise is limited. The magic phrase is “in-network provider does not have the subspecialty expertise required.”

If the plan will not authorize out-of-network, you can still see a cancer center on a self-pay basis. Many top centers offer cash-pay rates for second opinions ranging from roughly $400 to $2,500 depending on the scope.

Self-insured employer plans (ERISA)

Large employers who self-insure often include an explicit second-opinion benefit, under which the employee can obtain a cancer second opinion at a top center at no personal cost. Examples include Cleveland Clinic’s MyConsult, MSK Direct, and the Mayo Clinic Second Opinion Service.

Ask HR or look at your benefits summary. Many employees don’t know their employer has negotiated this benefit. Many of the top 20 U.S. employers offer it.

Virtual second opinions

Most major centers (MSKCC, MD Anderson, Dana-Farber, Cleveland Clinic, Johns Hopkins, Mayo, UCSF) now offer virtual second opinions. These services combine remote record review with a video consultation, typically $400 to $2,500 self-pay.

Insurance coverage for virtual second opinions is evolving:

• Many commercial plans cover them as telehealth consultations
• Medicare covers telehealth consultations with in-person or video follow-up
• Some self-insured employer plans have virtual-second-opinion-specific carveouts as a benefit

The cancer center’s financial team will verify your benefits before scheduling.

International second opinions

If you’re not in the U.S. but want an opinion from a U.S. cancer center, most centers offer international second opinion services. These are typically self-pay because foreign insurance doesn’t apply.

What about a pathology-only second opinion?

Sometimes the most valuable second opinion is just re-reading your pathology slides. Rare cancers and ambiguous pathology readings are the #1 source of misdiagnosis. Pathology-only review is:

• Cheaper ($200-$600 typically)
• Faster (often 3-7 days)
• Covered by Medicare as a pathology service
• Often covered by commercial insurance with prior authorization

Options: Johns Hopkins Pathology International Consultation, MD Anderson Pathology Second Opinion, MSKCC Pathology Consultation.

How to maximize your coverage

1. Call your insurance first and ask the specific question: “I want a second opinion at [center]. Is it covered? What’s my cost share? Do I need prior authorization?” Document who you spoke with and when.
2. Get any required referrals in writing. Don’t rely on your PCP remembering to fax it.
3. Ask the cancer center’s financial team to verify benefits before scheduling. They do this routinely and will provide a written estimate of what you will owe.
4. If denied, appeal. Cancer second-opinion denials are often overturned, especially for rare cancers or when in-network expertise is limited. Cite “medical necessity” and specific subspecialty expertise.
5. If you have self-insured employer coverage, ask HR about second-opinion programs before engaging the insurance process. The benefit may already exist.

If you’re uninsured

Many cancer centers offer sliding-scale or charity-care second opinions. Ask.

Virtual second opinions from $400-$2,500 self-pay are accessible without insurance.
