Is Oscar Health legit?

Legit, mixed reviews

You can trust that Oscar Health is a real insurer, one many people pick on the Obamacare marketplace, but getting care paid for is often where members struggle. Some treatments and medicines need its approval in advance, and a doctor or clinic that has left its network can cost you far more.

What we checked

  • Health insurer founded in 2012
  • Listed on the NYSE since 2021
  • Head office in New York City
  • Ratings on other review websites: 1.5/5

Watch out for

  • A treatment or prescription held up because it needs Oscar's approval before it is covered.
  • A bill from a doctor or clinic that turned out to be outside Oscar's network on the day of the visit.
  • A caller asking for your full Social Security number, which Oscar says it never asks for.

Did Oscar deny a claim you expected covered?

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

How do I contact Oscar Health customer service?

Oscar Health members can reach the Care Team on (855) 672-2755, or send the Care Team a secure message through the Oscar app or their online account. Have your member ID ready, and for a billing or claim question the claim number, the date of service and the name of the provider.

Claim or premium problem to put in writing? Start your complaint here as well, and we push it out to Oscar Health by email, social media and printed letters.

How do I appeal a denied claim with Oscar Health?

To appeal a denied claim with Oscar Health, start with the denial letter or the Explanation of Benefits: it gives the reason for the denial and explains how to ask Oscar to reconsider. Ask the Care Team on (855) 672-2755 to confirm the reason and whether the claim was simply coded or billed wrongly, because a corrected claim from your provider can settle that without an appeal. For a medical decision, ask your doctor for a letter explaining why the treatment is needed, and send the appeal in writing with your member ID, the claim number, the date of service and copies of the records. Note when each letter was sent and keep every reply.

Claim denied for a treatment your doctor says you need? Open a case with us: our trained AI keeps coaching you on what to send Oscar Health and when to push again.

How do I cancel my Oscar Health plan?

How you cancel an Oscar Health plan depends on how you enrolled. If you bought it through a public Marketplace, end the coverage in your Marketplace account; if you enrolled directly with Oscar or through an employer's ICHRA plan, contact the Care Team on (855) 672-2755 or message it through your Oscar account, and for an employer plan tell your employer as well. Ask for the end date of your coverage in writing, stop any automatic premium payment, and keep the confirmation.

If premiums keep being charged after the end date, compare the charges with the confirmation and ask Oscar in writing to refund the payments taken after it.

Can I complain to the Florida or New York Department of Financial Services about Oscar Health?

Yes: the Florida Department of Financial Services, Division of Consumer Services, handles insurance concerns about policies bought in Florida, including health insurance claims, coverage and premiums, and the New York State Department of Financial Services (DFS) takes complaints about insurance companies in New York, where Oscar Health is based. Both generally expect Oscar Health to have had the chance to put things right first, so keep a record of every call, letter and claim number.

Coverage or claim dispute with Oscar Health? We help you write the complaint in minutes through our complaint process, with each claim, letter and date set out in order.

Is that call from Oscar Health real?

Not if it asks for your full Social Security number. Oscar says it never asks for it, and it has warned members about fraudulent phone calls that try to get account details. Hang up on any caller who pushes for it, and never read out a code sent to your phone.

What do people complain about most at Oscar Health?

Nothing has been reported about Oscar Health here yet. Our research shows what typically goes wrong at US health insurers selling marketplace plans: claims denied or paid at the wrong rate, prior authorization requests that hold up treatment, doctors and pharmacies listed as in-network that turn out not to be, premium payments not applied and coverage terminated, surprise bills after a visit, and slow answers on appeals.

Coverage ended over a premium you did pay? Be the first to report it: your case opens the record for the next Oscar Health member with the same problem.

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 Oscar Health 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 Oscar Health complaint?

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