How Claim Audits Check for Billing and Coding Compliance

One of the Biggest Benefits of Medical Claim Audits

Billing and coding compliance is a major factor in the healthcare industry, especially for third-party claim administrators (TPAs) that manage company-funded medical plans. Billing and coding errors affect a plan’s beneficiaries access to needed healthcare and medications, could enable fraud and ultimately affect costs. With healthcare reimbursement as expensive and complex as it is, the stakes for accurate billing and coding have never been higher.

Medical claim auditing is a first line of defense because it makes certain that bills and the resulting claims are coded correctly, preventing financial losses, meeting fiduciary responsibilities, and assuring regulatory compliance.

Understanding Billing and Coding Compliance

Billing and coding compliance refers to the adherence to rules, regulations, and standards set by governmental agencies and payers when submitting medical claims. The process includes translating patient care into standardized codes—such as ICD-10, CPT, and HCPCS—that correctly depict the services provided. Errors in this process lead to improper payments, legal consequences, and damage to reputation for plan sponsors and healthcare providers. For pharmacy plans, plan benefits define the billing  and coding of drugs, with costs driven by contractual terms and guarantees which rely on a variety of rules as well as pricing standards that range from publicly available “Average Wholesale Pricing” (AWP) to proprietary Maximum Allowable Costs and numerous variations thereof.

Why Claim Auditing is Essential and Effective

Claim auditing is the systematic review of medical claims to ensure that billing and coding methods are accurate and comply with regulatory requirements. Auditing 100% of claims, as opposed to random sampling, enables organizations to detect every instance of upcoding, undercoding, and mismatched claims. This thorough technique catches honest mistakes and diminishes the risk of fraud, waste, and abuse, which are common and costly issues in healthcare reimbursement.

Upcoding and Undercoding: The Twin Threats

• Upcoding occurs when a provider uses a billing code that shows a more severe diagnosis or a more expensive procedure than was actually performed. This practice might lead to overstated claims and overpayments.
• Undercoding is the opposite—using a code for a less severe diagnosis or less expensive procedure.

While upcoding is the bigger cost concern for health plan sponsors, both are compliance violations. They can result in financial penalties and bring about legal issues.

The Claim Audit Process

A thorough claim audit includes several essential steps:

1. Data Collection: Collect all relevant claims data, including submitted codes, medical records, and payment information.
2. Review and Analysis: Compare billed services with the medical records to ensure that each code accurately represents the care provided.
3. Reporting: Document findings, highlighting any instances of upcoding, undercoding, or mismatched claims.
4. Corrective Action: Request changes to billing methods, suggest staff training, and propose revised policies to prevent future errors.

Benefits of Comprehensive Auditing

Auditing 100% of claims provides multiple benefits compared to random sampling:

• Increased Detection: All compliance violations are identified, not just a sample.
• Better Risk Management: Early detection of issues reduces the risk of large-scale financial losses or regulatory sanctions.
• Improved Data Validity: Guarantees the accuracy of claims data, supporting better decision-making for plan sponsors.
• Enhanced Provider Relationships: Supports clarity and trust between providers and payers.
• Plan Members: Accurate payments and full equal access to all the benefits a plan sponsor’s Employees and Dependents have been promised.

Challenges in Billing and Coding Compliance

Despite the benefits, maintaining billing and coding compliance is not exempt from challenges:

• Complex Regulations: Healthcare billing rules change frequently, demanding ongoing staff education and audit system upgrades.
• Volume of Claims: High claim volumes often strain internal resources, meaning comprehensive reviews require auditors’ state-of-the-art systems.
• Human Error: Coding is complex, and mistakes are common, even among experienced professionals.
• Technological Needs: Access to advanced audit software is essential to avoid limiting the effectiveness of reviews.

Best Practices for Assuring Compliance

To maximize the effectiveness of claim audits and ensure billing and coding compliance, organizations should adopt these best practices:

1. Access Audits and Technology

Automated claim auditing software can review 100% of claims quickly and accurately. These systems use artificial intelligence plus machine learning to spot potential compliance issues for human review.

2. Commit to Ongoing Training

Regular training for billing and coding staff ensures that they stay up-to-date with the latest regulations and coding standards. Training should cover common pitfalls, such as upcoding and undercoding, as well as new rules from CMS and other payers.

3. Develop a Culture of Compliance

TPA leadership should accentuate the value of compliance and create an environment where staff feel comfortable reporting errors or concerns. Establishing clear policies and procedures helps guide staff in proper billing methods.

4. Engage External Auditors

Independent medical and Rx plan auditors bring an unbiased perspective and can identify compliance issues that internal teams could miss. They add useful recommendations for improving processes.

The Role of Claim Audits in Company-Funded Medical Plans

For employers that sponsor self-funded health plans, claim auditing is particularly important. These companies or nonprofits bear the financial risk for claims paid, so inaccuracies directly impact their bottom line. Comprehensive claim audits help control costs, reduce the risk of fraud, and ensure that plan funds are used appropriately (fiduciary responsibilities).

Legal and Regulatory Considerations

Non-compliance with billing and coding regulations might result in considerable legal and financial consequences for providers. Regulatory bodies such as the Centers for Medicare & Medicaid Services (CMS), the Office of Inspector General (OIG), and the Department of Justice (DOJ) and State Attorneys General actively investigate and penalize fraudulent billing methods. Penalties can include:

• Repayment of overpayments
• Civil monetary penalties
• Exclusion from federal healthcare programs

On the flip side, plan sponsors must remain compliant through rigorous claim audits. In addition, sponsors have recently begun to be hit with class-action fiduciary breach lawsuits, which is another reason for claim auditing and tighter plan oversight and management.

Correct Codes Underpin Correct Claim Payments

As regulatory scrutiny intensifies, employer plans that apply advanced audits and continuous monitoring of claim payments will be better equipped to detect incorrect coding, sustain compliance, and protect their financial and legal interests.

Billing and coding review is a keystone of effective medical claim audits. By investing in oversight, encouraging a TPA culture of compliance, and auditing 100% of claims, sponsors reduce risk, control costs, and preserve the soundness of their health plans.

Frequently Asked Questions

Q1: What is the difference between upcoding and undercoding?

A: Upcoding is the practice of using billing codes that reflect more expensive services than were actually provided, resulting in overpayment. Undercoding is using codes for less expensive services, leading to underpayment. Both are compliance violations and can result in audits and penalties.

Q2: Why is it important to audit 100% of medical claims rather than just a random sample?

A: Auditing 100% of claims ensures that all instances of billing and coding errors, including upcoding and undercoding, are identified. Random sampling may miss significant issues, allowing non-compliance to go undetected and increasing the risk of financial loss or regulatory action.

Q3: What are the common challenges organizations face to maintain billing and coding compliance?

A: The main challenges entail keeping up with changing regulations, managing high claim volumes, preventing human error, and overcoming technology limitations. Ongoing training, investment in technology, and frequent audits help meet these challenges.

Q4: How can technology improve the claim audit process?

A: Automated audit software can quickly analyze large volumes of claims, marking potential compliance issues for further review. AI and machine learning increase accuracy and capability, permitting organizations to audit 100% of claims without inundating their staff.

Q5: What are the effects of non-compliance in billing and coding?

A: Noncompliance may lead to employee complaints and dissatisfaction, repayment of overpayments, civil monetary penalties, exclusion from government programs, and criminal charges in cases of intentional fraud. It can also damage the organization’s image and economic soundness.

Q6: How often should organizations conduct claim audits?

A: Best practice is to conduct ongoing, real-time audits using automated tools, supplemented by regular internal and external audits. Frequency may vary by the organization’s size, claim volume, and risk profile, but continuous auditing is ideal.

Q7: What steps should organizations take if they discover billing and coding errors during an audit?
