Undiagnosed Diseases Program


The Vanderbilt Undiagnosed Diseases Program exists to solve medical mysteries for patients with complicated conditions and rare diseases.

Our patients benefit from a team approach involving experts from across Vanderbilt University Medical Center.

Financial information

Insurance covers many services, such as lab tests and diagnostic imaging, that are a necessary part of diagnosing rare diseases. Vanderbilt contracts with many, but not all, insurance companies. If Vanderbilt contracts with the patient’s insurance company and the services are covered by the insurance policy, Vanderbilt will bill the insurance company for those services. We will work with your insurance company to get any “pre-authorizations” needed before you are seen and tests are run. Services not covered by insurance will be billed to the patient. Patients will also be charged an administrative fee for program costs not covered by insurance. We will discuss the anticipated costs with you before you make a decision about participation in the program. Following this, if there are certain services that your insurance company will not cover, we will notify you of the cost before you receive the service.
