What is the process for Appeals?

CERiS provides an appeal process for all claims on which their review has been utilized. Once an appeal is received, either by post mail or fax, it is logged and submitted to an Appeals Representative for review. The Appeal Representative will review all of the information and documentation submitted with the appeal.  If the Appeal Representative determines that the documentation requires the additional review of a medical review professional, the file will be resubmitted to our Medical Review Department for determination. 

Once a determination has been made on the file, the Appeals Representative will generate a response with the corresponding documentation to be faxed to the appeal contact.  Escalation of the appeal is not solely based upon the request of the provider, but is determined based upon the Appeal Representative’s research of the original determination, as well as, their review of the correspondence and documentation submitted by the provider and/or the provider’s representative.

How are Appeals submitted to CERiS?

An appeal can be submitted in writing by post mail or fax. When submitting your appeal, please indicate the charge or charges that you are disputing with supporting documentation for our appeals staff to review. Please also include a contact name, phone number and fax number to whom the appeal response will be sent.

Why is CERiS requesting an Itemized Bill?

As an agent of the payor(s) authorized representative, CERiS has been contracted to review the charges billed by the provider for the services. As such, additional documentation is required to review the services rendered and provide a recommendation to the payor(s) authorized representative accordingly.

Does CERiS review for medical necessity?

No.  CERiS is not reviewing for medical necessity.

Does CERiS issue any payments on the claim or perform any recoupments?

No. CERiS does not issue any payments or handle any recoupments on any of the claims reviewed.

Does a nurse or medical professional actually review the claim?

We do have a team of medical professionals, including Registered Nurses, Certified Surgical Technicians and Professional Medical Coders, with varying backgrounds and specialties, who will review the itemized charges submitted by the provider for payment.

Is the CERiS review an audit?

No. The review is not a traditional audit and is more of a claim edit. We are not reviewing the medical charges against the medical records, but rather, we are simply looking at the charges billed against national billing standards, removing any charges that may result in duplicate payment as the result of a billing error, duplicate charge, etc.

Our Purpose

At CERiS, our goal is to account for every item charged, for every hospital patient. We pride ourselves on holding our organization, our associates, and facility review process to the highest standards of integrity, objectivity and fair business practices. We understand the unique and sensitive nature of our partnerships and strive to maintain valuable relationships with our providers. Our reputation within the industry is built on fulfilling the payors fiduciary responsibility with trust and professionalism. It is with these two components we approach how we do business with you.

Additional Solutions

Beyond our itemization review, CERiS offers a complete array of services for in and out of network claims. 

Facility Repricing

CERiS provides comprehensive solutions for out of network claims. We help ensure claims accuracy by providing clinical reviews, while repricing to a range of methodologies that include reasonable and customary, reference based pricing, or a mix based on your needs.

Implant Repricing

These claims are clinically reviewed and referenced to our premier database that contains all manufacturer implant device invoice data from across the country. This information is used to determine average cost and reasonable account reimbursement. 


Our team of professionals has extensive legal, finance and healthcare experience and utilizes our average charge and cost databases for negotiations. We leverage our strong relationships with the provider community to achieve high acceptance, while averaging 25-45% in reductions on 50% of claims processed.

Professional Claim Review

Over 80% of medical claims contain incorrectly coded charges on professional fees such as services not administered, multiple billing for the same services, unbundling of global charges and coding errors. CERiS provides a clinical review and validation of medical claims for professional charges. Our clinical experts examine the course of care to identify gaps by cross checking the care provided and the billed charges.


Our clients share their stories.

“Our shared goal is to treat medical providers fairly while we identify errors and duplicate charges.   CERiS has the only true itemization review that we have seen that does both."

National Carrier Client
