As healthcare providers, have you ever felt like medical claims are playing hide and seek with your practice’s revenue? One misstep can lead you directly into the abyss of rejected or denied claims.

Think of a medical claim as a paper plane: a rejected claim is like a plane that never leaves the runway, grounded due to errors in patient information, improper coding, or formatting issues.

On the other hand, denials are more like a plane that takes off but gets redirected mid-flight because it doesn’t meet payers’ specific requirements. These claims come back marked with “try again.”

Understanding the difference between rejected and denied claims is essential to keeping your healthcare organization’s revenue cycle on track.

What are Rejected Claims?

When a claim doesn’t meet the initial requirements and standards set by the clearinghouse or payers, it can be rejected. Rejected claims cannot proceed further because errors are detected during the initial screening phase. Common issues that lead to rejections include invalid patient details, incomplete fields, incorrect coding, and noncompliance with format specifications.

Rejected claims do not enter the insurance payers’ adjudication system, so there’s no generation of an Explanation of Benefits (EOB) or Remittance Advice (RA). A claim rejection report is sent back to healthcare providers, outlining the reasons for rejection that need to be addressed before resubmitting the corrected claim.

When submitting claims, you may encounter various rejection codes from clearinghouses or insurance payers:

• Both primary and secondary insurance are listed as Medicare plans, which is not allowed.
• Subscriber claim filing indicator codes cannot be “MB” (Medicare Part B).
• An invalid diagnosis code needs correction to comply with the latest coding standards.
• Subscriber primary identifier is missing or invalid, preventing claim processing.
• Insurance type code is required but missing for non-primary Medicare payers.
• Referring provider name is missing.
• Missing pick-up location details for ambulance services claims.
• Subscriber ID or information doesn’t match payer records.

What are Denied Claims?

Sometimes, claims are processed by payers but marked as unpayable, resulting in a denial. Claim denials occur after the claim adjudication process, with the Explanation of Benefits (EOB) and Remittance Advice (RA) identifying the reasons for denial.

Denials can stem from issues like lack of medical necessity, services not covered by the patient’s insurance plan, or failure to obtain prior authorization. Denied claims can be addressed through a formal appeal process and supported by documentation to challenge the payer’s decision and secure payment.

Here are some common claim denial responses you may encounter:

• Lack of medical necessity
• Services not covered under the patient’s insurance plan
• Incorrect coding or invalid diagnosis
• Out-of-network providers (providers not in the insurance company’s network)
• Policy exclusions (claim falls under a specific exclusion)
• Incomplete information (missing patient demographics or provider details)
• Missing prior authorization

Key Differences Between Rejected and Denied Claims

It’s important for healthcare providers to distinguish between rejected and denied claims because each requires a different approach. Although both terms refer to claims, they have distinct meanings. Understanding the difference between these two helps streamline claim management and leads to faster reimbursement. Make a clear distinction between rejection and denial to improve financial health.

Initial Screening vs. Adjudication

Rejected Claims

Rejected claims can be identified during the initial screening process conducted by clearinghouses or insurance payer systems. These claims are marked as red flags for incorrect information or incomplete data, preventing them from entering the formal adjudication process.

For example, a claim can only be accepted if the patient’s date of birth is entered correctly or if no fields are left blank. Errors in claims detected early can be corrected immediately for further interaction with payers.

Denied Claims

In contrast to rejected claims, denied claims pass through the complete adjudication process by the insurance payer but are ultimately found to be unpayable. This can happen if the provided services are deemed not medically necessary or fall outside the insurance coverage.

Denied claims require a comprehensive appeal process that includes the submission of additional documentation and supportive evidence to challenge payer decisions, which can be complicated.

Understanding the Processing Stage

Rejected Claims

The processing stage for rejected claims can stop at the initial review, meaning claims can be sent back to healthcare providers immediately after submission. This immediate action allows healthcare providers to make necessary corrections and resubmit claims promptly. For example, a claim would be rejected for an incorrect procedural code, which can be fixed without delay.

Denied Claims

In the case of denied claims, the processing stage is completed, meaning the payer has reviewed the claim and marked it as unpayable based on policy guidelines or other patient-specific information. A claim denial clearly indicates that a deeper review has been conducted, such as verifying service coverage or medical necessity, and also involves formal notification that outlines the reasons for denial.

Identifying the Type of Errors

Rejected Claims

Common errors that cause claim rejections can be technical or administrative, and these errors are relatively simple to correct. There might be improper, invalid, or outdated use of ICD-10, CPT, or HCPCS coding. For example, the submitted code might no longer be valid. Failing to provide the provider’s NPI, patient demographics, or insurance information can also lead to rejection.

Denied Claims

Denied claims often arise from more substantive issues. Denials can occur due to errors in determining the correct insurance policy and the medical necessity of services. This requires a thorough review of clinical documentation to justify the need for medical services. Additionally, failing to secure prior authorization for certain services can result in denials.

Implementing Corrective Actions

Rejected Claims

Corrective actions for rejected claims should focus on identifying technical or administrative errors before submission. All data can be updated for rejected claims, such as patient demographics, procedure codes, and diagnosis codes. It’s important to verify all information before submission; automated audits and checks can be implemented to correct errors and reduce the likelihood of further claim rejections.

Denied Claims

Unlike rejected claims, denied claims involve a more formal appeal process that requires collecting and submitting additional documents to support the medical records, detailed treatment justifications, and letters of medical necessity. A proper appeal letter should be submitted to the payer to address all concerns, ensuring that the appeal process follows payer-specific guidelines and timelines.

Exploring Notification Methods

Rejected Claims

Rejected claims are accompanied by a rejection report that outlines the specific issues leading to the rejection. This report enables providers to immediately identify and correct errors, facilitating prompt resubmission. For example, the rejection report highlights any fields that are left blank or contain incorrect procedures.

Denied Claims

On the other hand, denied claims are accompanied by an Explanation of Benefits (EOB) or Remittance Advice (RA) that specifies the reasons for denial. This report provides detailed information on why claims are denied, such as lack of medical necessity or insurance coverage issues. Healthcare providers must review this document and fully understand the reasons for denial to plan an effective appeal.

Turnaround Time for Resolution

Rejected Claims

The turnaround time for resolving rejected claims can be shorter, allowing for quick corrections and resubmission without extensive documentation. Rejected claims can typically be sorted within a day or two, enabling the billing staff to update all information and ensure compliance with submission standards.

Denied Claims

Denied claims can take longer to address due to the need for appeals. This process involves gathering additional documentation, writing appeal letters, and waiting for payers to review and respond. This can extend from several weeks to even months, depending on the complexity of the denials.

Reasons for Claim Rejection

Claims can be rejected in the initial phase due to errors or invalid information. We have compiled several reasons why claims are rejected that need to be addressed immediately to avoid payment delays and revenue leakage.

1. Incorrect Patient Information: Incorrect details, such as the date of birth or subscriber ID, can lead to rejection. For example, if a patient’s name is misspelled, the claim will not be processed further. Accurate data entry is crucial for initial acceptance to ensure that all details are correct and match the information the insurance provider has on file.
2. Outdated or Invalid Codes: Using outdated, incorrect, or invalid ICD, HCPCS, or CPT codes can cause a claim to be rejected. A code that doesn’t match the treatment provided will be flagged. This highlights the importance of staying updated with coding systems and standards, which can prevent this issue and keep us informed and proactive.
3. Missing or Invalid Prior Authorization Numbers: Missing or invalid prior authorization numbers can also lead to rejection, especially for procedures that require pre-approval. Ensure that this information is corrected before submitting the claim.
4. Duplicate Claims: Submitting the same claim multiple times without correction can also lead to rejection.
5. Invalid Payer ID: Submitting the claim with an invalid payer ID is a common reason for claim rejection, as the claim cannot be routed correctly. Always cross-check the payer ID before submitting claims.
6. Non-compliance with Payer Guidelines: If the claim format does not adhere to payer guidelines, it can also result in rejection. Proper formatting guidelines must be strictly followed.

Reasons for Claim Denial

Claim denials require more extensive resolution efforts that include appeals and additional documentation. Here are some reasons that can trigger claims to be denied by payers:

1. Medically Necessary Treatment: If payers identify that the treatment is not medically necessary, the claim can be denied. Payers may require detailed documents and justifications to support the claim.
2. Coverage Limitations: If services are not covered under the patient’s insurance policy, claims can be marked as denied. It’s important to understand the limitations of your insurance policy.
3. Incorrect or Inconsistent Billing Practices: Practices such as unbundling services or upcoding can lead to denials.
4. Inactive Dates of Service: If patients do not have an active date of service, the claim can be denied. Always cross-check eligibility before services are rendered to mitigate these risks.

How to Follow Up on Rejected and Denied Claims

Following up on rejected and denied claims is important for ensuring timely reimbursement and maintaining a balanced revenue cycle. Here’s how you can manage follow-ups for both rejected and denied claims.

Follow Up on Rejected Claims

1. Review the Rejection Report: Start by reviewing the rejection report provided by the clearinghouse to identify errors or missing information.
2. Correct and Resubmit: Once all errors are corrected, resubmit the claim. Ensure that all information is accurate and completely adheres to the payer’s formatting guidelines.
3. Track Resubmitted Claims: Keep track of resubmitted claims and ensure they are processed successfully. Use an automated system to monitor the status and follow up on these issues.
4. Implement Regular Audits: Try to implement a regular audit system to catch errors before claim submission and resolve them immediately.

Follow Up on Denied Claims

1. Review the EOB or RA: Carefully review the Explanation of Benefits (EOB) or Remittance Advice (RA) to understand the specific reasons for denial.
2. Gather Supporting Documentation: Collect all additional information and documentation required to support the appeal, such as physician notes, prior authorization, or any other relevant medical records.
3. Prepare and Submit Appeals: Prepare and submit formal appeals to insurance payers, addressing all denial reasons with supportive documentation. Ensure that you completely follow the insurance payer’s specific appeal process guidelines and timeframe.
4. Monitor Appeal Status: Regularly monitor the status of your appealed claims and follow up with payers as needed. Keep a comprehensive record of all payer-provider communication for timely resolution.
