My Explanation of Benefits says the claim was denied but that I owe $0. What does that mean, and what should I check?

In short

  1. An EOB is not a bill, so read the line for what you owe.
  2. Ask the plan for the specific reason its notice must give [4].
  3. For some care out of network, Texas limits what you can be billed [1] [2] [3].

What this means

Two numbers on that page do different jobs. One is what the provider charged. The other is what the plan says you owe. Why a claim can be denied while your share is zero is not something these sources explain. For a job-based plan the notice itself must carry the reason [4]. The practical test is simpler. Does the office bill match the you-owe line? If the reason turns out to be that the plan does not cover the service, these sources do not say the office is barred from billing you.

Texas does put facts on that page for some care. Was the service by an out-of-network provider? Then the notice in your Explanation of Benefits must state the billing prohibition that applies [1]. It must also give the total the provider may bill you, with the copayments, coinsurance, deductibles and other amounts itemized [1]. So for those claims the page itself shows your ceiling.

The ceiling is firm for emergency care. Under an exclusive provider plan, an out-of-network provider may not bill you more than your copayment, coinsurance and deductible, and you do not have financial responsibility above that [3]. The amount is based on what the insurer first determined payable, or on a modified amount from its own internal appeal [3]. The chapter sets the same kind of limit for emergency care under a preferred provider plan [2]. A bill above that is the one to dispute in writing.

Is your plan through a job? Then the denial notice has its own content rules. It must give the specific reason or reasons for the decision [4]. It must point to the plan provisions the decision is based on [4]. It must describe any more material or information you need to send, and why it is needed [4]. And it must describe the plan review procedures and their time limits [4]. If your page does none of that, ask for those four things by name.

Your next step

Put the EOB next to the office bill and compare the you-owe line with the amount billed. Write to the plan and ask for the specific reason for the denial in plain words [4]. If the bill is higher than the you-owe line, write to the office too, quote the total the provider may bill you from the notice [1], and ask for a corrected bill. Was it emergency care out of network? Say in the letter that you do not have financial responsibility above your copayment, coinsurance and deductible [2] [3]. The sources give no deadline for those letters, so date them and keep copies.

Check it yourself

Find three lines on your EOB: billed amount, plan paid, and patient responsibility. Then find the billing-prohibition statement and the total you may be billed [1]. If your plan is through a job, check whether the notice gives the four things the federal rule lists [4]. What a particular denial code on your page means: "Don't know yet" here, so ask the plan to spell it out.
