Provider based billing

No Surprise Billing

When you're treated by an out-of-network provider at an in-network facility, you are protected from balance billing. In these cases, you shouldn't be charged more than your plan's copayments, coinsurance and/or deductible. Learn about your rights and protections against surprise medical bills
