CO-107 Denials Explained: How to Identify, Appeal, and Prevent Them

Denial codes are a persistent challenge for healthcare revenue cycle management (RCM) teams, and CO-107 denials are no exception. This denial code arises when claims lack references to related or qualifying services, leading to revenue delays and operational inefficiencies. Understanding the root causes of CO-107 denials and mastering strategies for appeals and prevention is critical to maintaining financial health in today’s complex healthcare landscape.

In this article, we’ll break down the CO-107 denial code, compare it to similar codes, explore common causes, and provide actionable steps for appeals and prevention. By the end, you’ll have the knowledge and tools to protect your organization’s revenue and streamline your denial management process.

What Is a CO-107 Denial?

The CO-107 denial code indicates that the related or qualifying claim/service was not identified on the submitted claim. This denial stems from missing or incomplete references to prior claims or services that are essential for the payer to process the current claim.

Prefix Breakdown

• CO (Contractual Obligation): This prefix signals that the denial is due to the provider’s contractual agreement with the payer, making the provider financially responsible for addressing the issue.
• In contrast, other prefixes like PR (Patient Responsibility) or OA (Other Adjustment) shift responsibility to the patient or other entities.

In the case of CO-107, the provider bears the financial responsibility for resolving the denial, as it relates to claim submission errors or omissions.

Comparison: CO-107 vs Similar Denial Codes

Denial Code	Prefix Meaning	Reason/Description	Who's Financially Responsible
CO-107	Contractual Obligation	The related or qualifying claim/service was not identified on this claim.	Provider
CO-109	Contractual Obligation	Claim/service not covered by this payer/contractor.	Provider
PR-22	Patient Responsibility	This care may be covered by another payer per coordination of benefits.	Patient

While CO-107 and CO-109 both fall under contractual obligations, CO-107 specifically relates to missing references to related claims, whereas CO-109 involves non-covered services. PR-22, on the other hand, shifts responsibility to the patient, often due to payer coordination issues.

Common Causes of CO-107 Denials

1. Missing Reference to Prior Claim or Service: Failure to link the current claim to a previous claim or qualifying service, such as a prerequisite procedure.
2. Incomplete Clinical Documentation: Insufficient details in the claim to justify the relationship to a prior service or procedure.
3. Incorrect Claim Submission Format: Errors in the 837 claim file, particularly in the 2110 loop where related claim information should be included.
4. Payer Policy Variances: Lack of awareness or adherence to payer-specific requirements for referencing related claims.

Impact on Revenue Cycle Teams

CO-107 denials create significant financial and operational challenges for healthcare organizations:

Financial Impact

• Revenue loss due to delays in claim resolution and potential write-offs.
• Increased accounts receivable (AR) days, affecting cash flow and financial planning.
• Higher operational costs from rework and appeals.

Operational Impact

• Staff time diverted from other critical RCM functions to manage denials.
• Increased need for clinical documentation reviews and payer-specific expertise.
• Added complexity in tracking denial trends and managing appeals.

To address these challenges, healthcare organizations should implement robust denial management strategies.

Steps To Appeal a CO-107 Denial

If your organization receives a CO-107 denial, follow these steps to resolve it:

Step 1: Review the Denial Notice

Carefully analyze the explanation of benefits (EOB) or remittance advice (RA) to confirm the denial reason and identify missing references.

Step 2: Gather Documentation

Compile all necessary documentation, including prior claim details, clinical notes, and any other supporting materials that establish the relationship between services.

Step 3: Verify Eligibility

Ensure the patient’s eligibility and coverage details align with the payer’s requirements for linked claims.

Step 4: Prepare Appeal Letter

Draft a clear, concise appeal letter that includes:
- Patient and claim details
- Explanation of the denial reason
- Supporting documentation
- A request for reconsideration

Step 5: Submit Within Deadline

Payers typically have strict timelines for appeal submissions. Ensure your appeal is submitted promptly to avoid forfeiting your right to dispute the denial.

Step 6: Track and Follow Up

Monitor the appeal status and follow up with the payer as needed to ensure timely resolution.
