Medical Bills and Insurance, Explained
Almost every medical bill problem is more winnable than the letter implies. A denial is an opening position, not a verdict. A surprise bill is often a billing error or a protection you can invoke. An EOB you can't read is hiding numbers you may not actually owe.
These guides cover the whole money fight: reading an EOB line by line, appealing a denied claim, disputing a surprise or balance bill, getting prior authorization approved, negotiating a cash price, applying for hospital charity care, and handling a bill that has gone to collections. Each one is written from thousands of real patient stories, so the steps match how the system actually behaves, not how the paperwork says it should.
Start with the guide that matches the letter on your table. If you want the reading and the drafting done for you, text Kite the bill or denial and it walks you through the next step.

Frequently asked questions
Should I pay a medical bill I think is wrong?+
Not until you have checked it. Request an itemized bill and your EOB, and compare them. Billing errors are common, and paying a disputed charge can weaken your position. You have the right to dispute a charge before paying, and doing so does not automatically send it to collections.
How long do I have to appeal a denied claim?+
It depends on the plan, but many give you 180 days from the denial for an internal appeal, then a window for an external review by an independent party. The deadline is printed on the denial letter. Appeal in writing, keep a copy, and note every date and name.
Can a hospital lower my bill?+
Often, yes. Nonprofit hospitals are required to offer financial assistance (charity care), and most bills can be reduced through a self-pay or prompt-pay discount, a payment plan, or negotiation against the cash price. Ask for the financial assistance application before you agree to any amount.
