How to Call Your Health Insurance Company

Last updated: March 19, 2026

Over 300 million Americans have some form of health insurance, and at some point nearly all of them need to call their insurer. Whether it's a denied claim, a confusing bill, or a procedure that needs pre-authorization, the phone is still the fastest way to get real answers. The problem is that insurance phone trees are designed to keep you away from a human. Here's how to get through.

Where to find your number

Flip your insurance card over. You'll usually see two or three phone numbers — one for member services, one for providers, and sometimes one for mental health or behavioral health. You want the member services number. If you've lost your card, log into your insurer's website or app. The number is also on every Explanation of Benefits (EOB) statement they've mailed or emailed you.

What to have ready

Insurance reps verify your identity before they'll tell you anything. Have these within arm's reach:

• Your insurance card — member ID number and group number are both on the front.
• Date of birth — the primary policyholder's, not yours, if you're on someone else's plan.
• Provider name and NPI — if you're calling about a specific doctor or facility. The NPI (National Provider Identifier) is a 10-digit number you can look up at npiregistry.cms.hhs.gov.
• Dates of service — the exact date(s) of the visit, procedure, or claim in question.
• Claim or reference numbers — from your EOB or a previous call.
• A pen and paper — write down the rep's name, the time you called, and any reference number they give you. This matters if you need to call back or file a complaint.

Getting through the phone tree

Most health insurers use a similar automated system. Here's the general flow:

What to say (by topic)

Checking if something is covered (benefits verification): Before a procedure or specialist visit, call to confirm it's covered under your plan. Ask for the specific benefit, your copay or coinsurance amount, and whether prior authorization is needed.

Pre-authorization: Some procedures, medications, and specialist visits require approval before you get the service. Your doctor's office usually handles this, but you can check the status yourself or find out if something needs it.

Claim status or denied claim: If a claim was denied, ask for the exact reason — insurers use specific denial codes. This is your starting point for an appeal. Under the Affordable Care Act, you have the right to appeal any denial.

Finding in-network providers: In-network means lower costs. Ask the rep to confirm a specific doctor is in-network, or ask them to find in-network providers near you for a specific specialty.

Filing an appeal: If your claim was denied, you can appeal. Ask for the appeals department, the specific denial reason, the deadline (usually 180 days for internal appeals), and where to send your appeal letter. If the internal appeal is denied, you have the right to an external review.

Tips for faster answers

• Call Tuesday through Thursday. Mondays get the weekend backlog. Fridays, people are trying to close things out before the weekend. Mid-week is lighter.
• Avoid January and open enrollment periods. The weeks after January 1st are flooded with new-plan questions. If your issue isn't urgent, wait until February.
• Use the app for basics. Most major insurers — UnitedHealthcare, Anthem, Aetna, Cigna, Blue Cross Blue Shield — have apps where you can check claims, find doctors, and view your ID card. Save the phone call for the stuff that actually needs a conversation.
• Ask for a reference number. Every call should generate one. Write it down. If you call back, give the next rep that number so you don't have to repeat your entire story.
• Request written confirmation. If the rep tells you something is covered or approved, ask them to send you that in writing (email or letter). Verbal confirmations are hard to enforce.
• Know your rights. Under the ACA, insurers must provide an internal appeal process and an external review. If you're stuck, your state's department of insurance can help.
