# When A Claim Is Denied

Here are a few tips to follow if you get billed for a medical, dental, or vision service that you thought was covered by your plan.

## Create A Paper Trail

Before you act, have all your claim documentation. This includes:

* Copies of claim denial letters and your explanation of benefits
* Any correspondence between you and your health care provider (doctor, hospital, or lab), as well as any correspondence between your health care provider and your medical plan
* Detailed notes of any phone conversations with your plan provider

## Know Your Plan Rules

Your medical plan has a formal process for resolving disputes about denied claims. Read your plan rules to learn the specifics about your plan’s process. Contact your [medical plan’s claims department](https://www.nvidiabenefits.com/resources/contacts-and-policy-numbers#Medical) with any questions. Summary plan descriptions are available on the [U.S. Benefits Enrollment Site](https://nvidiabenefits.bswift.com/).
