A second opinion is when you consult a different doctor about a diagnosis, recommended treatment, or surgical plan to confirm the original recommendation or explore alternative options. Getting a second opinion is your right as a patient, and your health insurance plan covers it.
ACA-compliant plans cover second opinions as part of your standard medical benefits. You'll pay whatever cost-sharing applies to a specialist visit (copay or coinsurance, depending on your plan), but the visit itself is a covered service. If the second opinion doctor orders additional tests or imaging, those are also covered under your plan's normal terms.
A second opinion is especially valuable when you're facing a major decision: surgery, cancer treatment, a new diagnosis of a chronic condition, or any situation where the treatment carries significant risks, costs, or life impact. Studies show that second opinions change or refine the diagnosis or treatment plan in a meaningful percentage of cases.
Some plans and situations may require a second opinion. For example, your insurer might require a second surgical opinion before approving a non-emergency procedure. In that case, the plan usually directs you to a specific second-opinion provider and covers the visit in full.
To get a second opinion, you typically don't need a referral (unless you're in an HMO that requires one). Choose a doctor who specializes in your condition, ideally at a different practice or health system from your original doctor. Bring your medical records, test results, and imaging so the second doctor has full context.
Good doctors expect and encourage second opinions for major medical decisions. It's standard practice and your right as a patient. If a doctor discourages you from seeking a second opinion, that itself may be a reason to get one.
It depends on your plan. PPO plans typically cover out-of-network second opinions at a higher cost-sharing rate. HMO plans may not cover out-of-network opinions unless it's an insurer-required second opinion. Check your plan's rules and consider whether an in-network specialist is available first.
