Understanding a medical bill, and disputing one

Never pay a medical bill until your insurer's explanation of benefits has arrived and the two documents agree. Ask for an itemized bill, check every line, and remember that the first number a hospital sends is an opening position, not a final price.

Understanding a medical bill, and disputing one

The paperwork, in order

After a visit, two documents arrive separately. The explanation of benefits comes from your insurer and is not a bill. It lists what the provider charged, the lower rate the insurer negotiated, what the insurer paid, and the amount marked as your responsibility. The bill comes from the provider, often weeks later, and a hospital stay can produce several of them from the facility, the surgeon, the anesthesiologist and the laboratory. The amount on each bill should match the patient responsibility line on the matching explanation. When it does not, or when no explanation exists yet, do not pay. Call the billing office and ask whether the claim was actually submitted to your insurance.

Ask for the itemized bill

A summary bill that reads "hospital services" tells you nothing. Request an itemized statement with billing codes, which you are entitled to receive, and read every line. The common errors are duplicate charges, charges for services or medicines you never received, a canceled test that was billed anyway, a wrong insurance number, and a preventive visit coded as a diagnostic one. Dispute errors in writing and keep copies.

Protections worth knowing

The federal No Surprises Act bars out-of-network balance bills for most emergency care, and for out-of-network clinicians who treat you at an in-network hospital. In those cases you owe only your normal in-network share. If you are uninsured or paying cash, you are entitled to a good faith estimate in advance, and you can dispute a final bill that exceeds it by four hundred dollars or more. If your insurer denies a claim, you have the right to an internal appeal and then to an external review by an independent party. The denial letter states the deadline.

If the bill is right but impossible

  1. Ask for the hospital's financial assistance application, because nonprofit hospitals are required to have a written charity care policy, and many forgive bills for incomes well above the poverty line.
  2. Ask for a prompt-payment or self-pay discount, which billing offices grant more often than people expect.
  3. Ask for an interest-free payment plan, and offer a monthly amount you can truly sustain.
  4. Keep the debt off your credit card, which converts a negotiable, interest-free bill into a fixed, expensive one.

Tip Before any scheduled procedure, call your insurer with the billing codes from the provider's office and ask what you will owe. The answer is easier to argue about before the surgery than after it.
