What is the CO 20 Denial Code? 

The CO 20 denial code signifies that the billed procedure or service is not covered by the patient's insurance plan. This denial occurs when the responsibility for payment lies with another party, such as an insurance company or a liability carrier. Understanding the complexities of medical billing and the CO 20 denial code is crucial for healthcare providers to maintain financial stability and provide quality care to their patients. 

Denial Code 20 Explained 

Denial code 20 means that the injury or illness being claimed is covered by the liability carrier. In other words, the healthcare provider's claim for reimbursement has been denied because the responsibility for payment lies with another party, such as an insurance company or a liability carrier. 

Common Reasons for Receiving a CO 20 Denial Code 

• The injury or illness being treated is related to a liability claim, such as a workplace injury or a motor vehicle accident. In these cases, the liability carrier is responsible for covering the medical expenses.
• The healthcare provider may have submitted the claim to the wrong insurance carrier.
• The documentation provided by the healthcare provider may not clearly indicate that the injury or illness is related to a liability claim.
• The liability carrier may have specific requirements or guidelines for processing claims related to injuries or illnesses.
• The claim may be missing necessary supporting documentation, such as accident reports or witness statements.
• The healthcare provider may not have obtained the necessary authorization or approval from the liability carrier before providing treatment.
• The liability carrier may have specific coverage limitations or exclusions that apply to the injury or illness being treated.
• Errors or inaccuracies in the claim submission, such as incorrect patient information or coding mistakes.
• The liability carrier may have reached its coverage limit for the specific injury or illness.
• Changes in the liability carrier's policies or procedures. 

Financial Implications of a CO 20 Denial Code 

A CO 20 denial code can delay or reduce reimbursement, requiring additional time and resources for appealing the denial or resubmitting the claim. This impacts revenue, cash flow, and overall profitability. 

Best Practices for Resolving CO 20 Denial Code 

• Verify insurance coverage: Before providing any services, it is crucial to verify the patient's insurance coverage. Ensure that the patient's liability carrier information is accurate and up to date.
• Obtain pre-authorization: For certain procedures or treatments, obtain pre-authorization from the liability carrier.
• Accurate documentation: Ensure that all relevant information, including the details of the injury or illness, is accurately documented in the patient's medical record.
• Clear communication: When submitting claims, ensure that all necessary information is included and accurately conveyed.
• Stay updated with liability carrier policies: Regularly review any updates or changes in coverage criteria to ensure compliance.
• Utilize technology and automation: Implement revenue cycle management software or tools to streamline the claims submission process and reduce errors. 

How to Address Denial Code 20 

• Review the patient's insurance information: Verify that the patient has provided accurate and up-to-date insurance information.
• Gather necessary documentation: Collect all relevant documentation related to the injury or illness.
• Contact the liability carrier: Reach out to the liability carrier to initiate the claims process.
• Follow up regularly: Stay in touch with the liability carrier to ensure that the claim is being processed in a timely manner.
• Coordinate with other parties involved: If there are multiple parties involved in the liability claim, collaborate with them to ensure a smooth claims process.
• Monitor the claim status: Regularly check the status of the claim.
• Document everything: Maintain detailed records of all interactions, documentation, and steps taken throughout the claims process.
• Appeal if necessary: If the liability carrier denies the claim or provides inadequate reimbursement, consider appealing the decision.
