Is Anthem legit?

Legit, mixed reviews

Anthem is a real, large health insurer, the Blue Cross Blue Shield plan in states such as New York and Ohio, yet its card does not guarantee every bill gets paid. Some care needs Anthem's approval first, so a scan or operation your doctor booked can still be refused or billed as out of network.

What we checked

  • Owned by Elevance Health, Inc.
  • Head office in Indianapolis, Indiana
  • Parent listed on NYSE as ELV
  • Ratings on other review websites: 1.5/5

Watch out for

  • An Explanation of Benefits showing a claim turned down as not medically necessary, after the treatment already happened.
  • A separate bill from a lab or specialist outside the network, even though the hospital itself was in network.

Did Anthem refuse to pay for your treatment?

We help you write it, it gets its own public page, and you can have it sent to Anthem as a formal letter.

Common customer service questions about Anthem

How do I file a complaint about Anthem?

Do you have a dispute or a bad customer experience with Anthem? Report it through our website to maximize the chance of getting it resolved.

We help you write an effective complaint in minutes. Our AI models are trained on thousands of effective complaint letters. Then we push it through emails, social media, paper complaint letters and other tools at our disposal. And you are not alone: our helpful community is there for advice.

How do I contact Anthem customer service?

Anthem publishes no single national customer service phone number, because its contact details differ by state and by plan. Members find the Member Services number on the back of their Anthem ID card, or log in to their Anthem account on the website or in the Sydney Health app to see the contact details for their plan and start a live chat. If you are not a member yet, the Anthem contact page, linked in the contact details above, asks you to choose your state first. Have your member ID, the claim number and the date of service ready.

Claim or bill you want to dispute? Start your complaint here as well, and we push it out to Anthem by email, social media and printed letters.

How do I appeal a denied claim with Anthem?

To appeal a denied Anthem claim, start with the denial letter or the Explanation of Benefits: it gives the reason for the decision and explains how, and by when, to ask Anthem to review it. Write to Anthem with your member ID, the claim number, the date of service and the reason you believe the claim should be paid, and add the itemized bill and any supporting medical records. Where the denial says a service was not medically necessary, ask your doctor for a letter explaining why you needed it.

The plan documents in your Anthem account set out the grievance and appeal process for your plan. Employer plans, Medicare plans and Medicaid plans each follow their own appeal rules, so check which kind of plan you have before you write.

Claim denied as not medically necessary? Bring it through our complaint process: our trained AI opens a case for you and keeps coaching you on what to send Anthem next and when to push again.

Where is the Anthem corporate office?

Anthem is a brand of Elevance Health, Inc., whose corporate headquarters is in Indianapolis, Indiana; the address is in the contact details above. Anthem plans are sold under the Anthem Blue Cross and Anthem Blue Cross and Blue Shield names by Elevance Health companies that are independent licensees of the Blue Cross and Blue Shield Association.

The corporate office is not a member service desk. To escalate a complaint, ask Member Services to record it as a formal grievance, quote your member ID and every earlier reference, and ask for written confirmation that it has been logged. A letter to the head office can follow as a copy, with the same references and the outcome you want.

Can I complain about Anthem to the Indiana Department of Insurance or the New York State Department of Financial Services?

Yes: in the US, the Indiana Department of Insurance, Consumer Services Division takes complaints about insurance companies licensed in Indiana for policies issued there, and the New York State Department of Financial Services (DFS) takes complaints about insurance companies in New York, Anthem included. Both generally expect Anthem to have had the chance to put things right first, so keep a record of every call, letter and claim reference.

Bill or denial you want set out clearly? We help you write the complaint in minutes, drawing on thousands of complaint letters that actually worked.

What do people complain about most at Anthem?

Nothing has been reported about Anthem here yet. Our research shows what typically goes wrong at large health insurers: claims denied or paid at the wrong rate, prior authorization requests that hold up treatment, surprise bills from providers outside the network, premium charges and billing errors, enrollment changes and ID cards that do not come through, and Member Services numbers that differ by state and plan.

Explanation of Benefits showing a denial for care your doctor said you needed? Be the first to report it, and the next Anthem member facing the same denial has a case to point to.

What happens after I submit my complaint?

Your complaint gets its own public page on Complain.biz and we get to work: we bring it to the attention of Anthem through emails, social media, paper complaint letters and other tools at our disposal.

And we stay with it after you file. Our trained AI opens a case file for you and keeps coaching: what to reply, when to push again, and how to escalate if nothing happens.

Can other consumers help me with my Anthem complaint?

Yes. We have an active community of consumers, and complaints here are public: people who ran into the same problem with Anthem can give you advice or back you up with their own story. A complaint with a community behind it is much harder to overlook.
