What Do I Do If My Insurance Company Denied a Claim I Thought Was Covered?
Getting a bill or an explanation of benefits that shows “denied” next to something you were sure was covered is one of those moments that feels both confusing and a little infuriating. The good news is that a denial is rarely the final word, and there’s a fairly standard process for challenging it.
The short answer
The general first step is to request a written explanation of the denial from the insurer, since it’s required to state the specific reason. From there, most policies include a formal appeals process, often with more than one level, that allows a claim to be reconsidered with additional documentation or a clearer case for why it should have been covered. State insurance regulators also offer an external review option in many cases if the internal appeal doesn’t resolve things.
Start with the written denial explanation
Insurers are generally required to provide a written reason for denying a claim, not just a vague “not covered” notice. This document, sometimes called an explanation of benefits or a formal denial letter, typically cites the specific policy provision or medical necessity determination behind the decision. Reading it carefully matters, since denials happen for a range of reasons: a coding error, a missing prior authorization, a provider being outside the plan’s network, or a genuine coverage exclusion. Each of those points toward a different next step.
Understand the internal appeals process
Most insurance policies include a formal internal appeals process, and it’s usually described in the policy documents or the denial letter itself. This typically involves submitting a written appeal, sometimes with supporting documentation from a provider explaining why the service was medically necessary or otherwise should be covered. Internal appeals often have more than one level, meaning a denial upheld at the first stage can sometimes still be escalated within the company before other options come into play.
Deadlines matter more than they seem
Appeals generally come with strict deadlines, both for filing the initial appeal and for the insurer to respond. Missing a deadline can close off options that were otherwise available, so it’s worth noting the relevant dates as soon as the denial letter arrives rather than setting it aside.
What happens if the internal appeal doesn’t work
If an internal appeal is denied again, many states offer an external review process, where an independent third party outside the insurance company evaluates the claim. This option generally exists specifically because internal appeals alone don’t always feel like a fair hearing when the same company that denied the claim is also the one deciding the appeal. A state department of insurance is typically the right resource for understanding what external review looks like in a given state, since the exact process varies.
Other things worth keeping track of
- Keep a written record of every call. Names, dates, and what was said tend to matter later if a dispute drags on.
- Ask what documentation would change the outcome. Sometimes a denial comes down to a missing form or a note from a provider, not a fundamental coverage issue.
- Watch how a denial interacts with your out-of-pocket maximum. A claim that should have counted toward that limit but was denied instead can affect the math on what’s owed for the rest of the year.
- Understand that certain billing situations carry specific protections, particularly around out-of-network emergency care, which sometimes overlap with denial disputes.
What to weigh
A denied claim isn’t automatically the end of the conversation. Requesting the written reason, understanding the internal appeals process and its deadlines, and knowing that external review exists as a further option, tend to be the pieces that turn a frustrating denial into a claim that gets a fair second look.
