Exploring the Differences and Benefits of Concurrent Audits, Prospective Audits, and Retrospective Audits

Hospital decision-makers face the delicate balance of submitting claims quickly while ensuring the utmost accuracy, as claim errors can trigger costly delays, denials, or even regulatory scrutiny. To navigate this challenge, many healthcare facilities turn to audits to identify coding issues and ensure accurate reimbursements.

But when it comes to auditing practices, which approach is best: concurrent, prospective, or retrospective audits? Each type of audit offers distinct advantages and drawbacks, and understanding their differences can help healthcare providers choose the most effective strategy for their needs.

What Are Concurrent, Prospective, and Retrospective Chart Reviews?

Before diving into the specifics, let’s define each type of audit:

Concurrent Audits: Real-Time Oversight

Concurrent audits are conducted during the patient’s care or before claim submission, allowing coders and compliance teams to review documentation and coding in real-time. The goal is to identify and correct errors before claims are submitted to payers, ensuring accuracy and reducing the likelihood of denials.

When should I use a concurrent audit? Use concurrent audits for real-time accuracy. If your primary goal is to prevent errors before claims are submitted, concurrent audits are the best choice. They help ensure that claims are accurate and compliant from the outset, reducing the risk of denials and improving cash flow.

Concurrent audits are particularly useful for high-volume environments such as inpatient care or outpatient services where timely submissions are critical. This audit type is ideal when an organization needs to keep the revenue cycle moving smoothly without sacrificing accuracy. For instance, if a physician’s documentation lacks the specificity required to support a particular diagnosis code, the audit process can highlight this issue while the patient is still under care, allowing for timely corrections.

Prospective Audit: Pre-Submission Validation

Prospective audits, also known as pre-implementation or preoperative audits, are conducted before services are provided or a procedure is performed. These audits review cases to ensure medical necessity, verify prior authorizations, and confirm that planned procedures meet payer requirements. The goal is to prevent claim denials by catching potential issues before the claim is ever submitted.

When should I use a prospective audit? Use prospective audits in the pre-authorization process, where they serve to confirm that all requirements are met before services are provided. This proactive approach allows healthcare organizations to make necessary adjustments in advance, reducing the likelihood of coding or billing errors.

These audits are especially effective for high-risk, high-dollar services, where ensuring that the claim meets all necessary requirements can significantly reduce the risk of denials or payment delays.

Retrospective Audit: In-depth Post-Claim Review

Retrospective audits are conducted after claims have been submitted and, ideally, adjudicated. This means the claim has either been paid, denied, or is still pending. A retrospective audit aims to conduct a deep dive into the claim, identifying any errors or trends that might be affecting the organization’s billing processes. By reviewing claims that have already gone through the payer’s system, auditors can uncover systematic issues that may not have been evident during the submission process.

When should I use a retrospective audit? Use retrospective audits for root cause analysis. If you want to uncover systemic issues in your billing and coding processes, retrospective audits are ideal. They provide a comprehensive review of previously submitted claims, helping you identify trends and root causes of recurring issues.

Retrospective audits are invaluable for analyzing the broader picture of an organization’s billing practices. For example, if certain types of claims are being consistently denied or adjusted, the audit process can highlight these recurring problems, allowing healthcare providers to implement corrective actions. Moreover, retrospective audits can also help identify overcoding and undercoding, ensuring that the organization is optimizing its revenue cycle without risking compliance violations.

These audits are beneficial for organizations with a large volume of claims or those that are experiencing increased denials. While retrospective audits can’t prevent errors from occurring in the first place, they offer critical insights for continuous process improvement. They can serve as a foundation for future audits, including prospective ones.

The Pros and Cons of Each Type of Audit

Each audit type serves a specific purpose and can be used to meet different organizational goals. Let’s examine the advantages and limitations of concurrent, prospective, and retrospective audits.

Concurrent Chart Reviews

Advantages:

• Timely Detection of Errors: Concurrent audits offer real-time feedback to coders and providers, catching errors as they occur and preventing inaccurate claims from being submitted to payers in the first place. This is crucial for maintaining claim accuracy and reducing the risk of denials.
• Improved Compliance: By reviewing coding and documentation before claim submission, concurrent audits help ensure compliance with regulatory requirements and payer-specific guidelines. This proactive approach reduces the likelihood of audits, fines, or penalties.
• Faster Claims Processing: Since errors are corrected before claims are submitted, the reimbursement process is expedited, leading to faster payments and improved cash flow for the organization.

Disadvantages:

• Resource Intensive: Concurrent audits require dedicated resources and staff to review patient charts and documentation in real-time. This can increase the workload on coding and auditing teams, particularly in large healthcare organizations with high volumes of claims.
• Limited Scope: The sample size for concurrent audits is often small, meaning that only a limited number of cases are reviewed. This can lead to gaps in identifying errors across a broader range of claims.

Prospective Chart Reviews

Advantages:

• Preemptive Error Prevention: Prospective audits help identify potential billing or coding issues before services are provided, ensuring compliance with payer requirements and reducing the risk of claim denials.
• Ensures Compliance with Regulations: By verifying medical necessity and confirming prior authorizations ahead of time, prospective audits help ensure that planned procedures align with regulatory standards and payer guidelines.
• Enhanced Resource Planning and Risk Identification: These audits allow healthcare organizations to assess capacity risks and compliance issues before services are provided, enabling better planning and resource allocation.

Disadvantages:

• Limited Sample Size: Since prospective audits focus on a small sample of cases selected based on high-risk criteria, they may not provide a complete picture of overall coding and billing accuracy for all claims.
• Potential Delays in Service Implementation: The review process may slow down the initiation of procedures, as it requires verification and approval before services are rendered, which can impact scheduling and patient care.

Retrospective Chart Reviews

Advantages:

• Comprehensive Review: Retrospective audits allow for a more thorough review of claims that have already been submitted. This in-depth analysis can uncover trends, recurring issues, or areas of non-compliance that may not be apparent in a smaller sample of prospective claims.
• Larger Sample Size: Since retrospective audits focus on claims that have already been processed, auditors can analyze a larger dataset. This increases the chances of identifying systemic issues or trends that might be affecting billing and coding accuracy.
• Root Cause Analysis: One of the key benefits of retrospective audits is the ability to identify the underlying causes of recurring issues. Whether it’s problems with documentation, coding, or compliance processes, retrospective audits help organizations pinpoint the root causes of errors and develop corrective action plans.

Disadvantages:

• Doesn’t Prevent Errors from Going Out: Unlike concurrent and prospective audits, retrospective audits cannot prevent incorrect claims from being submitted. This means errors may have already resulted in delayed payments, denials, or other compliance issues.
• Time Delay: Since retrospective audits are conducted after claims have been adjudicated, the process may take longer to uncover issues and resolve them. This delay can affect the timely resolution of billing issues and may delay payments.

Combining Audits for a Comprehensive Strategy

While each audit type has its strengths, the most effective strategy for ensuring billing accuracy and compliance often involves a combination of concurrent, prospective, and retrospective audits. By leveraging the strengths of each audit, healthcare organizations can create a more robust revenue integrity program that addresses both immediate issues and long-term process improvements.

For example, an organization could start with a retrospective audit to identify broad trends and systemic issues. Then, it could use the insights from the retrospective audit to inform a more focused prospective audit of high-risk areas or specific providers. Finally, concurrent audits can be used in real-time to ensure that claims are accurate before they are submitted.
