Bill vs EOB
EOB Says Insurance Paid but I Got a Bill Anyway
When your EOB shows insurance paid but the provider still bills you, the bill may be for your coinsurance, deductible, or a service not covered.

Quick answer
If your EOB shows insurance paid and you still receive a bill, the bill may be for your remaining patient responsibility, a service not covered by your plan, or an out-of-network balance. Compare the EOB patient responsibility to the bill amount.
Understand What Insurance Paid Means
The Insurance Paid line on your EOB shows what your plan sent to the provider - but that is rarely the total amount the provider receives. Your plan pays its share, and you owe the rest. The bill you receive is typically for the patient responsibility portion.
Verify the Bill Amount
Compare the bill amount to the patient responsibility total on your EOB. If they match, the bill is correct. If the bill is higher, the provider may be billing for amounts not approved by your plan.
Out-of-Network Balance
If you received care from an out-of-network provider, the provider may balance bill you for the difference between their charge and what insurance paid. This is legal in most states unless the No Surprises Act applies.
What the research says
Most health insurance plans require the patient to share costs through copays, coinsurance, or deductibles.
Frequently asked questions
If insurance paid, why do I owe anything?
Insurance paying its share does not mean your share is zero. Your plan typically covers a percentage of the allowed amount or pays after you meet your deductible.
Can I dispute the bill if insurance already paid?
Yes, if the bill exceeds the patient responsibility on your EOB. The provider should not bill you for more than your EOB states you owe.
