CO-27 Denial Code: Expenses Incurred After Coverage Terminated

If you’ve been in the medical billing industry for a while, you’ve probably encountered denial codes that can disrupt the revenue cycle. One of the most common among them is CO-27 Denial Code, which stands for “Expenses Incurred After Coverage Terminated.”

The CO-27 denial code is assigned when an insurance company rejects a claim because the date of service falls outside the period of active coverage. In simple terms, the patient’s insurance was no longer valid on the date the service was provided.

This code is commonly included in the explanation of benefits (EOB) or remittance advice (RA), notifying the provider that payment has been denied due to terminated coverage.

Common Causes of the CO-27 Denial Code

The CO-27 denial often results from issues related to insurance coverage, data errors, or verification gaps. Recognizing these causes can help reduce denials and streamline claims processing.

1. Terminated Insurance Policy: This denial is common when a patient’s policy is no longer active due to non-payment, job changes, or policy expiration. If the coverage lapses and isn’t renewed, the claim will be rejected.
2. Incorrect Insurance Information: Claims get denied when outdated or incorrect insurance details are provided. Patients may forget to update their coverage information after switching plans, leading to submission errors.
3. Data Entry Errors: Simple mistakes like incorrect policy numbers, wrong service dates, or misspelled names can cause claims to be denied. Even minor errors can lead to major setbacks if not caught early.
4. Failure to Verify Eligibility: Eligibility checks performed too early or overlooked entirely can result in denials. If the patient’s coverage changes before the date of service and this isn’t verified, the claim will be rejected.
5. Coordination of Benefits Issues: When patients have multiple insurance policies, it’s crucial to bill the primary insurer first. Failing to do so or misidentifying the primary payer often triggers a denial until the claim is processed in the correct order.

5 Steps to Resolve a Denial Code CO-27

Resolving a CO-27 denial requires a structured approach to identify and correct the underlying issue. Timely action can prevent delays in reimbursement and ensure claim accuracy. Follow these steps to address it effectively:

• Verify Coverage: Begin by confirming the patient’s insurance status on the date of service. Use the insurance provider’s online portal or contact their customer service for the most accurate and up-to-date information. Ensure the policy is active during the service period.
• Check for Errors: Carefully review the claim for common data entry mistakes, such as incorrect policy numbers, service dates, or patient information. These errors are often the root cause of denials and should be corrected before resubmitting the claim.
• Contact the Patient: If the insurance policy was terminated, reach out to the patient for clarification. Ask them if they have obtained new coverage or updated their existing policy. Collect any new insurance details to update the claim accurately.
• Resubmit the Claim: Once all errors are corrected and the patient’s coverage is verified, resubmit the claim with the correct information. Ensure you attach any necessary supporting documentation to avoid further issues.
• Appeal if Necessary: If the claim is still denied after corrections, file an appeal with the insurance company. Provide evidence of active coverage during the service period or documentation that supports the validity of the claim. Appeals should be submitted promptly to meet the insurer’s appeal deadline.

Prevention Strategies for CO-27 Denials

Prevention is always more efficient than dealing with denials after they occur. By implementing proactive strategies, you can significantly reduce the chances of CO-27 denials and improve claims processing.

• Perform Real-Time Eligibility Checks: Always verify the patient’s insurance coverage on the date of service. Eligibility checks should be conducted in real-time to ensure the policy is active and the patient is covered. This step can prevent most coverage-related denials.
• Train Staff on Data Accuracy: Accuracy in data entry is crucial. Ensure your billing staff is well-trained to double-check policy numbers, service dates, and patient information before claim submission. Even small errors can lead to claim denials.
• Update Patient Information Regularly: Make it a routine practice to collect updated insurance information from patients at each visit. Coverage details can change frequently, and relying on old data increases the likelihood of denials.
• Use Automated Eligibility Tools: Take advantage of technology by using automated eligibility verification tools. These tools provide real-time updates on coverage changes, reducing manual errors and ensuring accurate claims submission.
• Establish Clear Communication with Patients: Educate patients on the importance of informing your office about any changes in their insurance coverage. Clear communication can help avoid surprises and ensure claims are submitted with the correct information.

How CO-27 Denials Can Impact Your Revenue Cycle

Denied claims can disrupt the revenue cycle and create financial challenges for healthcare practices. Here’s how CO-27 denials can affect your practice:

• Delayed Payments: Denials lead to delays in reimbursement, causing cash flow issues and increasing accounts receivable.
• Higher Administrative Costs: Investigating, correcting, and resubmitting claims require additional time, staff effort, and resources.
• Reduced Efficiency: Repeated denials slow down the billing process, diverting staff from focusing on other critical tasks.
• Potential Financial Losses: If not resolved promptly, denied claims may go unpaid, leading to lost revenue for the practice.
• Signs of Underlying Problems: Frequent CO-27 denials may indicate issues such as inadequate staff training or poor eligibility verification processes that need immediate attention.
• Impact on Patient Experience: Addressing denials can result in longer resolution times, which may affect patient satisfaction and trust.

Importance of Documentation and Follow-Up

Effective documentation and timely follow-up are critical when dealing with CO-27 denials. Ensure that every interaction with the insurance company is documented, including dates, times, and names of representatives you spoke with. 

This information can be crucial when filing an appeal or following up on a pending claim. Develop a systematic follow-up process to track the status of all denied claims. Assign dedicated staff members to manage claim follow-ups, ensuring nothing slips through the cracks.

Conclusion

While the CO-27 Denial Code may cause frustration, resolving it is entirely manageable with the right steps in place. Prompt action to verify insurance coverage, correct errors, and resubmit claims will minimize delays.

Preventive strategies, such as automating eligibility checks and consistently updating patient insurance details, can greatly reduce CO-27 denials. Denials are an inherent part of the billing process, but by staying proactive and focused, you can keep your revenue cycle smooth and your practice’s finances stable.
