What Is Out-of-Network Reimbursement
Out-of-network reimbursement is the amount your insurance company pays toward a medical bill when you receive care from a provider who has no contract with your plan. Your insurer sets this reimbursement level independently, often based on what they consider "reasonable and customary" charges in your geographic area. You receive an Explanation of Benefits (EOB) showing what the insurer paid, what you owe, and how they calculated the reimbursement rate.
How Reimbursement Is Calculated
Your insurer typically reimburses out-of-network claims using one of three methods:
- Percentage of billed charges: Your plan pays 60 to 80 percent of what the provider bills, leaving you responsible for the balance plus any deductible or coinsurance.
- Usual, Customary, and Reasonable (UCR) amount: Your insurer compares the provider's fee to the average charge for that service in your zip code. If the provider bills $2,000 for an MRI but the UCR is $1,200, the insurer may only reimburse based on the $1,200 figure. You still owe the remaining $800 plus your cost-sharing.
- Fee schedule: Some plans use fixed reimbursement rates for specific procedures, regardless of what the provider actually charges.
Why Denials and Underpayments Happen
Insurance companies frequently deny or reduce out-of-network reimbursements claiming lack of prior authorization, lack of medical necessity, or that the charge exceeds reasonable limits. Many states require insurers to pay out-of-network claims at a level that ensures adequate access to care, but enforcement varies. If your claim was denied or underpaid, check your EOB for the specific reason code.
Common grounds for appeal include:
- The insurer failed to obtain prior authorization before you sought emergency care, which many states protect from penalty.
- The provider was in-network at the time of service, but the insurer's records show otherwise.
- The UCR amount the insurer used does not reflect current market rates in your region.
- The claim involves mental health or addiction services, which carry separate state-mandated parity requirements.
Internal and External Appeals
Most state insurance regulations require a two-step appeal process. File an internal appeal with your insurance company within 30 to 180 days of the EOB (depending on your state and plan type). If the insurer denies the internal appeal, you can request an external appeal to an independent reviewer. Many states require insurers to cover external appeal costs if the reviewer decides in your favor. Document everything: the EOB, the provider's bill, your medical records showing why you needed out-of-network care, and any communications with your insurer about prior authorization.
Common Questions
- Can I be charged more than my insurer reimburses?
- Yes. Out-of-network providers are not bound by your plan's negotiated rates. You are responsible for any amount the provider bills above what your insurer pays. However, emergency out-of-network care receives stronger protections in most states, limiting what providers can balance-bill.
- Does the amount my insurer reimburses count toward my deductible?
- Not typically. Your deductible usually applies before the insurer pays anything. So if your deductible is $1,500 and a provider bills $3,000, you may owe the full $1,500 deductible plus coinsurance on the remaining balance, regardless of what the insurer considers "reasonable."
- What if I didn't get prior authorization because it was an emergency?
- Federal law and most state laws protect emergency out-of-network care from prior authorization requirements. If you faced a true emergency, the insurer cannot penalize you for lack of authorization. Document the emergency circumstances on your appeal.
