5 Payer Audit Errors Every Hospital Must Avoid

5 payer audit errors

Revised September 2022

Most healthcare providers, from large hospitals to solo practitioners, experience an external audit at some point. The scrutiny can unveil errors and violations, which can lead to hefty penalties. 

The key to surviving an external audit, with the least amount of frustration, is to avoid these five common mistakes. 

1. Late Responses

Your deadline to submit relevant documentation begins upon receiving that external audit request. 

External audits may be requested by a commercial health insurance payer, or government agencies such as the Centers for Medicare and Medicaid Services (CMS) or Office for Civil Rights (OCR). While the origin of the audit request doesn’t matter, a timely response is essential. 

Take all deadlines seriously. If an extension is needed, ask for one, immediately. Missing deadlines can result in hefty fines and penalties. 

2. The Wrong Documentation

A common trigger for payer audits is improper or lack of necessary documentation.  As a healthcare practitioner, you must prove the medical necessity of each test or procedure used to diagnose and treat your patients. 

Here’s the tricky part. Sometimes payers and providers disagree on what tests or procedures are medically necessary.  Additionally, medically necessary guidelines change frequently. CMS provides local coverage determinations (LCDs) and national coverage determinations (NCDs) to help with your documentation. Be sure you are aware of changes to these coverage determinations.  

The best way to mitigate this problem is to educate your staff on what services the payer considers medically necessary, and what documentation is required to establish medical necessity. 

 Additionally, clearly document the need for a particular procedure to treat or diagnose a patient. Finally, when required, ensure that authorization is received from the payer before rendering services. 

3. Billing the Wrong Codes

Incorrect billing and coding practices can raise suspicion of fraud, failed claims, or delayed reimbursement, and — you guessed it — external payer audits. Providers and patients overpay a whopping $68 billion annually due to incorrect billing. 

 Coding systems developed by the American Medical Association and the Centers for Medicare and Medicaid are designed to streamline the billing process. Every medical procedure and service from ambulance rides to chemotherapy drugs to doctor visits are contained within coding systems such as the ICD-10, CPT, and HCPCS. 

Studies show 80 percent of medical bills in the U.S. contain errors. This percentage can decrease by ensuring appropriate staff stay current with billing and coding updates and communicate those changes to the right clinical and administrative staff to avoid old and outdated codes. 

4. No Self-Audit

One way to prepare for payer audits is to perform regular self-audits within your facility.  Internal audits are great for identifying and eliminating weak spots that can potentially lead to headaches down the road, like rejected claims and costly compliance failures. 

 One drawback is the strain on precious resources like time and personnel. You can get around this problem by hiring a third-party audit service. Make sure you have HIPAA-compliant Business Associate Agreements (BAA) so that you’re allowed to share your patient health information with third parties providing auditing services.  

 Another option is to use software provides 24/7 access to survey compliance data. Ideally, this software will provide automatic tracking of all documentation and decisions involved in the process of running your organization. 

 This ensures that compliance professionals can get immediate reporting on how well their team is doing, conducting audits more efficiently and effectively. It’s a time and cost-effective solution to hiring an outside third-party provider. 

5. No Legal Help

Having a healthcare attorney in your corner can mean the difference between a smooth audit experience and an audit nightmare. 

Here’s how a healthcare legal team can benefit your health practice: 

  • Work intimately with your staff to analyze any risky billing procedures. 
  • Challenge any demands from payers for overpayment. 
  • Challenge any allegations of fraudulent billing practices. 
  • Push back on any denied claims and the overuse of service claims. 

 Again, software is a useful tool to support your attorney’s work. A system that stores all compliance information, including payment practices, and has search capability will provide your legal team with the information they need to fight payer audit discrepancies when the time arrives. 

 External payer audits don’t have to be a nightmare. By being adequately prepared and vigilant, your next audit experience can be more streamlined and less stress-inducing.
