Provider Disputes or Appeals


CareSource provides several opportunities for you to request review of claim or authorization denials. Actions available after a denial include:


Peer-to-peer rights are separate and distinct from your clinical appeal rights. If you received an authorization denial, your peer-to-peer rights were provided in your denial letter from CareSource. Please refer to your denial letter to exercise your available peer-to-peer rights. CareSource provides peer-to-peer reviews as an additional level of review for your pre- or post-service medical necessity requests. If a Peer-to-peer is requested, it must be completed prior to you submitting a clinical appeal.

Clinical Appeals

A clinical appeal is a written request by a provider to review a prior authorization denial with a clinical decision regarding medical necessity. Clinical denials are issued from the CareSource Utilization Management department. You may submit clinical appeals pre- or post-service. All pre-service appeals are clinical appeals and require the member’s AOR. For more information about requirements for pre- and post-service appeals, view the Clinical Appeals section below.

Claim Dispute

A dispute is typically submitted prior to submitting a claim appeal. You can submit a claim payment dispute when you disagree with payment and any other post-service claim denial.

Claim Disputes

If you believe a claim was processed incorrectly due to incomplete, incorrect or unclear information on the claim, you should submit a corrected claim. You do not need to file a dispute or appeal. Refer to the Claims page or the Provider Manual for further information related to claims submission.

Process for Claim Disputes

Requests for adjustment for underpayment or overpayment may be submitted through the claim dispute process. You do not need to submit an appeal for this type of review.

A request for review of a claim denial should be submitted as an appeal.

Claim disputes must be submitted in writing.

The dispute must be submitted within 90 calendar days of the date of payment.

At a minimum, the dispute must include:

  • Sufficient information to identify the claim(s) in dispute
  • A statement of why you believe a claim adjustment is needed
  • Pertinent document to support the adjustment

Incomplete requests will be returned with no action taken. The request must be resubmitted with all necessary information within 90 calendar days of the claim payment or 10 calendar days of the date on the letter notifying you of the incomplete request.

Claim disputes can be submitted to CareSource through the following methods:

  • Provider Portal
  • Fax: 937-531-2398
  • Mail: CareSource
    Attn: Provider Appeals Department
    P.O. Box 2008
    Dayton, OH 45401

CareSource will render a claim dispute decision letter within 30 calendar days of receipt. If the decision is to uphold the original claim adjudication, providers may appeal the claim adjudication if timely filing rights still apply.

Claim Appeals

If you do not agree with a denial on a processed claim, you have 365 calendar days from the date of service or discharge, unless otherwise specified in your contract, to submit an appeal.

If you do not submit the appeal within the required time frame, CareSource will not reconsider the claim, and the appeal will be denied. You will receive notification in writing if the appeal is denied. If your appeal is approved, your payment will appear on the Explanation of Payment (EOP).

Please note: If you believe a claim processed incorrectly due to incomplete, incorrect or unclear information, you should submit a corrected claim through the claim submission process. You do not need to file a pre-service appeal. You have 365 days from the date of service or discharge to submit a corrected claim.

Peer-to-Peer Process


CareSource provides the opportunity for providers to discuss the Utilization Management (UM) medical necessity determination of a denial or decrease in level of care with CareSource’s Medical Director/Behavioral Health Medical Director or designee within five business days of the notification of the determination. The peer-to-peer process is independent of the appeal process and does not impact the timeframe a member and/or provider has to appeal.

To initiate the peer-to-peer process, please call CareSource’s Utilization Management team at 1-833-230-2168.

Clinical Appeals

If you disagree with a clinical decision regarding medical necessity, we make it easy for you to be heard.

After receiving a letter from CareSource denying coverage, a provider or member can submit a pre-service or post-service clinical appeal.

  • Pre-Service Appeal: denial of an authorization for a service prior to being completed. You have 60 days from the date of the authorization denial to submit a pre-service appeal. The pre-service appeal must be accompanied with a member’s written consent, must be specific to the service requested, is only valid for that appeal and must be signed/dated by the member. You can use the Consent for Provider to File an Appeal on Patient/Member’s Behalf form, available on our Forms webpage.
  • Post-Service Appeal: denial of an authorization for a service that has already been completed. You have 180 days from date of service, discharge or authorization denial to submit a post-service appeal. Member consent is not required for post service requests.

If you have not received an authorization denial from the CareSource Utilization Management Department for a service that requires a prior authorization, you must submit a retro-authorization request prior to filing a clinical appeal.

How to Submit Appeals

You can submit appeals through our Provider Portal or using the Navigate Provider Appeal Form. The Provider Portal is the most efficient method of submitting appeals. Clinical appeals can also be submitted on the Provider Portal.

Include the following required documentation:

  • Progress notes including symptoms and their duration, physical exam findings, conservative treatment that the member has completed, preliminary procedures already completed and the reason service is being requested.
  • Any documentation of specialists’ reports or evaluations, any pertinent previous diagnostic reports and therapy notes.
  • If the service has already been provided, a copy of the original remittance advice and/or the denied claim.
  • If filing an appeal on behalf of a member or for pre-service issues, the member’s written consent, which must be specific to the service being appealed, is only valid for that appeal and must be signed by the member. Please note: You can use the Navigate Consent for Provider to File an Appeal on Patient/Member’s Behalf form to record this consent.
