You’ve probably been there. You’re sitting in a busy medical office, a patient is waiting, and you just need to verify a quick authorization or check why a claim was kicked back. You search for the oscar insurance corp provider phone number and end up in a loop of automated menus. Honestly, it’s frustrating.
Oscar Health isn't like the old-school legacy carriers that have been around since the 70s. They built their tech from the ground up, which means they really, really want you to use their portal. But sometimes, a screen isn't enough. You need a human.
The Number You Actually Need
Let’s cut to it. If you are a healthcare provider or billing specialist trying to reach Oscar Health, the primary line is (855) 672-2755.
But wait. Don't just hit "dial" and hope for the best. If you want the actual Provider Services team, you have to hit Option 4.
If you are dealing specifically with the Oscar Provider Portal—maybe you're locked out or a new staff member can't get their permissions right—there is a slightly more direct route for technical support. You can call the same main number, hit Option 4, and then hit Option 5 in the sub-menu. This gets you to the Portal Support team specifically.
Why the "Care Team" Number is Different
You might see (855) 672-2755 listed for members, too. That’s because Oscar uses a "Care Team" model. While it’s the same 10 digits, the routing is what matters. Providers who ignore the prompts and try to talk to a member representative usually get transferred back into the queue. Save yourself the twenty minutes.
Claims, Credentialing, and the Email Workaround
Sometimes the phone isn't the best way. I know, "expert" advice usually says "call them," but Oscar is a tech company at its core.
If you’re checking on credentialing, calling often leads to a representative telling you it's "in process." For a real paper trail, email credentialing@hioscar.com. They typically respond within 1 to 3 business days. If you’re a new provider trying to join the network, don't even bother calling; they’ll just point you to the "Join Our Network" form on their website.
For claims, here is a breakdown of how to handle it without losing your mind:
- Electronic Claims (EDI): Use EDI ID: OSCAR. This is the fastest way. Most claims processed this way get paid in about 5 to 7 days.
- Paper Claims: If you’re still doing paper (it happens), send them to: Oscar Health, PO Box 52146, Phoenix, AZ 85072-2146.
- Pharmacy Issues: Oscar often partners with CVS Caremark. If the issue is a prescription rejection at the pharmacy, the oscar insurance corp provider phone number above might not be the fastest. Check the back of the patient's ID card for the specific PBM (Pharmacy Benefit Manager) line.
What Most People Get Wrong About Oscar Support
People assume that because Oscar is "digital-first," they don't have a robust support system. That's not quite true. They just hide it behind a very specific hierarchy.
One thing that surprises a lot of office managers is the "Organization Administrator" role in the Oscar portal. If you can't see a feature—like managing payments—it’s usually not a system error. It's because your account wasn't given "Admin" status by whoever in your office first set up the Oscar account.
Oscar uses Optum Financial and ECHO Health for their actual money movements. If your question is "Where is my direct deposit?" and the Oscar portal says the claim is "Paid," the Provider Services team at Oscar might not have the check number. You might actually need to talk to ECHO Health.
When to Stop Calling and Start Typing
Honestly, the oscar insurance corp provider phone number is great for simple eligibility checks if the portal is down. But for complex appeals or clinical disputes, the portal is actually better.

Why? Because Oscar’s "Clinical Dashboard" allows providers to see the same view the insurance company has. You can upload documentation directly to a specific claim. When you call, the rep is basically looking at the same screen you are. If you’ve already uploaded the documents, the phone call becomes much more productive because you can say, "Look at the PDF I attached ten minutes ago."
A Note on State Specifics
Oscar has been shifting its footprint. Whether you’re in Florida, Texas, or New York, the central provider number stays the same, but the local "Provider Relations" reps are different. If you are having a systemic issue—like all your claims for a specific code are being denied—ask the phone rep for the contact information for your local Provider Relations Manager. These are the people who handle the business relationship between your practice and Oscar.
Actionable Steps for Your Billing Team
To keep your revenue cycle moving with Oscar, don't just rely on the phone.
- Register the Portal First: Use your NPI and TIN at provider.hioscar.com.
- Assign an Admin: Make sure your office manager is the "Org Admin" so they can invite other staff.
- Use the Right Sub-Menu: When calling (855) 672-2755, remember: Option 4 for providers, then Option 5 if it's a website tech issue.
- Verify via CAQH: Keep your CAQH profile updated. Oscar pulls their credentialing data from there. If your CAQH is expired, no amount of calling the provider line will get your claims paid.
- Check the EDI Status: If a claim is missing, check your clearinghouse first to ensure it cleared the "OSCAR" gateway before calling.
Log into the Oscar Provider Portal today and verify that your "Taxonomy Code" and "Service Location" match exactly what is on file with the CAQH to prevent future "Provider Not Found" denials.
