How to Call Your Health Insurance Company
Last updated: July 31, 2026
The number is on the back of your insurance card, under "Member Services." Most insurers answer Monday to Friday, 8am–8pm local, with a 10–30 minute wait — mid-morning Tuesday through Thursday is the shortest. Have your card, date of birth, and any claim numbers ready. 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.
- Phone number On the back of your insurance card (look for "Member Services")
- Hours Most insurers: Mon–Fri 8am–8pm local time (some offer 24/7 nurse lines)
- Avg hold time 10–30 minutes depending on insurer and time of year
- Best time to call Mid-morning Tuesday through Thursday
- Have ready Insurance card, date of birth, claim or reference numbers
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:
- Call the member services number on your card.
- Select your language (usually
1for English). - Enter or say your member ID number when prompted.
- You'll hear a menu — common options:
Press1for claims and billing
Press2for benefits and coverage
Press3for pre-authorization
Press0to reach a representative - If the system loops you or asks you to use the website, press
0repeatedly or say "representative" until you're connected.
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.
Example
"I'm scheduled for an MRI at [facility name] on [date]. Can you verify that this is covered under my plan and tell me what my out-of-pocket cost will be? Also, does this require pre-authorization?"
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.
Example
"My doctor submitted a pre-authorization request for [procedure] about a week ago. Can you check the status? The CPT code is [code] and the provider is [name]."
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.
Example
"I received an EOB showing my claim from [date] was denied. Can you tell me the specific denial reason and code? I'd also like to know the deadline and process for filing an appeal."
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.
Example
"I need to find an in-network dermatologist within 20 miles of [zip code]. Can you also confirm whether Dr. [name] at [practice] is currently in-network for my plan?"
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.
Example
"I'd like to file an appeal for claim number [number]. Can you transfer me to the appeals department? I need the mailing address and any forms required to submit my appeal."
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.
Common questions
Where do I find my health insurance phone number?
The customer service number is printed on the back of your insurance card. You can also find it on your insurer's website or on any Explanation of Benefits (EOB) statement. Look for the 'Member Services' number, not the provider line.
What should I have ready before calling my health insurance?
Have your insurance card (member ID and group number), date of birth, the provider's name and NPI number if relevant, dates of service for claims questions, and any claim or reference numbers from previous calls or EOB statements.
How do I get pre-authorization from my insurance company?
Call the member services number and ask for the pre-authorization or utilization management department. You'll need the procedure code (CPT code), the provider's details, and a clinical reason for the service. Your doctor's office often handles this, but you can call to check the status or start the process yourself.
How do I appeal a denied health insurance claim?
Call member services and ask for the appeals department. Request the specific denial reason and the deadline for filing an appeal. Under the ACA, you have the right to an internal appeal and, if denied again, an external review by an independent third party. Always get the appeal mailing address and any required forms during the call.
