Dear Appeals Department,

This letter constitutes a formal appeal of the above-referenced claim denial on behalf of rendering provider name and credentials of practice name. We respectfully request that your organization reconsider this denial and process the claim for payment in accordance with our provider agreement and your coverage policies.

Not Credentialed Denial

Argument: Provider Was Credentialed at Time of Service

The claim was denied on the basis that provider name was not credentialed with payer name at the time of service. This determination is incorrect. We provide the following evidence:

We request that this claim be reprocessed with an effective credentialing date of MM/DD/YYYY. Enclosed: copy of credentialing approval letter, application confirmation, and relevant contract provisions.

Timely Filing Denial

Argument: Claim Was Submitted Within the Required Filing Period

The claim was denied for failure to submit within the timely filing window. We dispute this denial on the following grounds:

We request reprocessing of this claim based on the original submission date. Enclosed: clearinghouse confirmation report, ERA/remittance history, and original claim copy.

Medical Necessity Denial

Argument: Services Were Medically Necessary and Covered Under the Member's Plan

The claim was denied on the basis of medical necessity. We strongly disagree with this determination and submit the following in support of our appeal:

We request an independent clinical review by a physician reviewer in the same specialty, as required under most state appeal regulations. Enclosed: clinical notes, operative report (if applicable), relevant imaging/lab results, and supporting clinical literature.

Out of Network Denial

Argument: Services Were Rendered Under Emergency / Continuity of Care Provisions

The claim was denied on the basis that provider name is out-of-network. We request reconsideration under the following provisions:

We request reprocessing at in-network benefit levels. Enclosed: documentation supporting the basis for appeal listed above, patient treatment records, and applicable regulatory references.

Resolution Requested: We respectfully request that payer name reconsider this denial and process the claim for the full billed amount of $0.00, or at the contracted/applicable rate, within 30 business days of receipt of this appeal.
