Essential 5 Step Medical Coding Audit Checklist

It’s an unfortunate reality: Many of today’s medical practices struggle with increased volumes of claim denials. There are a number of reasons why this is happening. Payer requirements, personnel shortages that tempt staff to “cut corners” when it comes to compliance, and a general lack of insight into medical coding and other denial trends are just a few reasons denials are up.

While there are no easy answers to prevent claim denials, one of the most effective ways to promote proactive compliance is to conduct an internal medical coding audit in your office.

Regular medical coding audits are absolutely essential. They help maintain coding accuracy, ensure compliance with regulations, and optimize reimbursement. To support a regular practice, this guide outlines a simple, structured approach to conducting internal medical coding audits.

Purpose of Medical Coding Audits in Healthcare🔗

Per an industry-wide survey on medical coding, 47% of medical practices audit internally. About a third audit quarterly (34%) or annually (32%), while just over a quarter audit at least monthly (26%). Regardless of how often it’s done, auditing your medical claims is paramount.

The purpose of medical coding audits in healthcare is threefold:

• Ensuring data integrity
• Promoting quality patient care and safety
• Enhancing business performance

Conducting medical coding audits is a key part of the Office of Inspector General’s (OIG) seven basic elements of a voluntary compliance program for physician practices—#6, to be exact.

An internal medical coding audit provides immediate feedback on what you are doing well and what you can improve, identifying and correcting coding errors. It enables you to intervene quickly and prevents staff from submitting inaccurate claims to payers, thereby preventing underbilling. In addition, coding audits enhance overall documentation quality, improving coder and clinician knowledge. They also produce valuable business insights, identifying trends and critical risks.

Given their importance, all medical practices should conduct coding audits regularly. A simple, five-step process makes it easier for all practices to start.

Step 1: Define Audit Objectives and Scope🔗

First, identify the focus of your internal medical coding audit. If this is the first time you’ve audited your medical claims, we recommend beginning with a baseline assessment.

An internal retrospective (post-bill) audit (i.e., auditing claims after payers have processed them) might be a good place to start because it can help you pinpoint areas of vulnerability that you might not have otherwise uncovered. From there, you can narrow your focus and shift to prospective (pre-bill) audits (i.e., auditing claims before payers have processed them).

While a bigger scope may seem ideal, narrowing the focus of your coding audit helps ensure your time is well spent on strategic priorities, and it often yields the biggest return on investment.

Whatever scope you choose, determine your sample size using factors like claim volume, risk areas, or previously uncovered issues. Ten to twenty claims per physician is usually a good place to start, although a larger sample will help determine trends and outliers more accurately.

Step 2: Assemble a Medical Coding Audit Team🔗

Before you start the audit itself, assemble a team to conduct the audit and analyze its findings. This starts with a careful process of identifying key roles for the audit team.

Staff to recruit for the audit team include, but are not limited to:

• Certified medical coders
• Compliance officers
• Billing specialists

With individuals in place, you’ll need to assign responsibilities accordingly. Clearly define roles (e.g., data collector, code assessor) for each team member to ensure efficient audit processes.

You’ll also need to provide training for everyone on the team. Ensure all stakeholders are fully up-to-date with coding guidelines, compliance requirements, and payer-specific requirements.

Step 3: Conduct the Medical Coding Audit🔗

This is where the medical coding audit proper starts. Using the scope determined in Step 1, your audit team will assess clinical documentation and medical coding accuracy. They’ll review any relevant patient records, physician notes, and billing statements to verify coding accuracy.

During this review, auditors should specifically verify that:

• Selected codes accurately reflect the documented services provided
• Modifiers are applied correctly and consistently
• Medical necessity is clearly supported in the clinical record

These issues are among the most common contributors to avoidable claim denials and delayed reimbursement.

A medical coding audit template may help with impactful, practice-based questions like:

• Does medical coding adhere to official coding guidelines?

• Does clinical documentation comply with payer requirements?

• Do documentation and medical coding satisfy all internal policies and procedures?

Members of the audit team should leverage coding audit software and resources to assist in the audit process, including the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) and Current Procedural Terminology (CPT®) manuals.

Step 4: Analyze Findings and Identify Trends🔗

Finding discrepancies is only half the battle; your team must also identify the root causes of any errors or omissions, ideally using a medical coding audit tool template. The first part of this root-cause analysis involves categorizing errors by type (e.g., documentation, coding, billing).

Once all discrepancies or issues are categorized, their impacts need to be understood. This involves analyzing potential short- and long-term financial and compliance implications for all issues and assigning scores or other numerical values for comparison. Teams can use those figures, along with estimated mitigation timelines, to prioritize which issues and root causes to address.

Identifying patterns can also help teams prioritize. Recurring errors indicate systemic problems in coding practices, which should be addressed sooner than one-off or inexplicable issues.

Step 5: Implement Corrective Actions and Monitor Progress🔗

Medical coding audits aren’t conducted just for their own sake; their findings need to be acted upon. Audit teams should work with leadership to develop action plans or strategies to address identified issues. Potential courses of action include additional training or process changes.

Physicians and other staff should be educated on areas of opportunity for improvement as well as areas of success. Consider providing additional training modules on how to assign a medical code. It’s also helpful to quantify the financial impact of the internal medical coding audit in revenue terms to make the stakes more obvious in operations-focused education programs.

Policies and procedures may need to be updated, as well. Some practices opt to create a comprehensive final report outlining practice-wide recommendations for improvement.

Audit teams and leadership should also regularly review subsequent audits to ensure corrective actions have been taken and are effective—and make adjustments in cases where they aren’t.

Optimize Your Medical Coding Audit Process🔗

Regular medical coding audits are vital for maintaining compliance, improving coding accuracy, and optimizing reimbursement. They’re a critical part of revenue cycle management (RCM).

Internal medical coding audits ensure clinical documentation integrity, improve patient care and safety, identify financial gaps and vulnerabilities, and help practices standardize their business practices to enhance overall performance. All this is much easier to achieve when following a straightforward process—and when working with a quality medical billing and RCM partner.
