OIG Watchlist: Radiology Billing Services Are Under Fire

 

 

Radiologists spend hours interpreting medical images, collaborating with other healthcare professionals, and guiding patient treatment.    

Radiology billing has landed squarely in the spotlight, and the attention is anything but flattering. The Office of Inspector General (OIG) has sharpened its focus on radiology billing practices across the U.S. They especially targeted those tied to radiology centers and outpatient departments.    

However, this scrutiny isn't based on guesswork. It follows mounting evidence of billing irregularities. That includes inconsistent coding to claims that simply don't match documentation.   

Why Radiology Billing Has Become a Federal Concern 

Radiology billing and coding are complex. It involves layered services, detailed modifiers, and billing codes that vary by payer. The industry sees a high volume of claims with a wide margin for error. That's exactly why it's come under OIG investigation.       

Recent additions to the OIG Work Plan highlight repeated issues with radiology claims. Many radiology billing services involve incorrect use of modifiers or improper billing for both technical and professional components. We have also observed duplicate submissions for the same service. These errors aren't just technical flaws; they point to larger compliance issues.   

When these mistakes occur consistently, they suggest more than oversight. They raise questions about billing integrity. That's when audits begin.   

What Imaging Centers Billing Mistakes Actually Cost 

Mistakes in radiology billing often lead to more than just denied claims. They damage payer trust. In some cases, they even threaten participation in insurance networks. Consequently, these missteps triggered delays, recoupments, and in several cases, OIG probes.   

Moreover, errors tied to CT scans, MRIs, and advanced diagnostic imaging frequently show up in audit reports. If radiology centers bill for services that are not medically necessary or misrepresent the complexity of procedures, they will eventually face OIG audits.   

Key Areas the OIG Is Watching 

OIG auditors are trained to detect patterns. Their current focus includes several recurring trouble spots: 

  • Dual billing of professional and technical components for the same procedure 
  • Frequent use of modifier -26 without appropriate documentation 
  • Inflated coding for complex imaging studies 
  • Repetitive use of certain high-reimbursement diagnosis codes 
  • Claims submitted without supporting provider notes 

Each of these issues can open the door to audits, fines, or worse. Once flagged, a practice can face reviews that go back several years.   

Practical Ways to Avoid Audit Risk

Radiology providers don't need to fear audits if they stay ahead of them. Routine internal audits are a good first step. Moreover, they should check recent claims for accuracy. It helps in flagging issues before they become patterns.   

Here, imaging centers' billing services must submit all-inclusive documents to payers. Vague or inconsistent reporting is a top reason claims get returned or denied. Hence, radiologists should ensure documentation explains the thorough medical necessity and procedure scope.   

The Role of Certified Coders in Preventing Errors 

Coders are the first line of defense in revenue protection. But not all coders are created equal. Imaging centers should prioritize hiring or partnering with certified coders who understand the nuances of radiology billing.   

Credentials such as the CPC or RCC confirm that a coder has training in CPT, HCPCS, and ICD-10 specific to imaging. With certified staff reviewing documentation and assigning codes, error rates drop and compliance improves.   

Moreover, untrained staff may overlook small but costly details, like improper use of modifier TC or failing to separate components correctly. As a result, the imaging center may face claims denials and loss of reimbursement.   

Data Security Is Also Under Scrutiny 

OIG oversight doesn't end with codes. It also includes how patient and billing data are handled. Centers should ensure their systems meet HIPAA and HITECH requirements. They need to use encrypted platforms for sharing documentation. Moreover, radiologists should limit data access to essential staff only.   

Auditors check more than just codes. They evaluate how safely practices store and transmit sensitive information. If the patient data isn't secure, everything else falls apart.

When Outsourcing Becomes the Smarter Option 

Not every imaging center has the time or staff to handle complex billing internally. Moreover, employing qualified billing experts and certified coders may break the bank of radiology centers, especially for small practices. Here, outsourcing will be a smart move. However, choosing the right outsourced radiology billing company is crucial.   

To ensure optimum accuracy, centers need to choose a third-party vendor that specializes in radiology billing. Moreover, radiologists need to ensure the billing vendor has in-depth experience with payer audits and that they keep up with regulatory changes. Furthermore, these outsourced billing partners are significantly cost-effective. Radiology centers can save up to 80% of operational costs with their assistance.   

In addition, radiology billing outsourcing services should offer thorough claim tracking and detailed performance reports. This allows providers to retain full oversight without managing daily operations.  

Imaging Centers shouldn't wait for an OIG Letter 


Some providers treat audits as an unexpected problem. The smarter move is to treat them as preventable ones. Regular compliance checks should be part of your routine operations. Whether in-house or third-party, having a compliance officer or consultant periodically review billing trends makes a big difference.   

Being proactive builds credibility with payers. It also ensures you can respond quickly if questions come up about your billing patterns. The OIG isn't out to punish honest providers. But it is holding radiology billing to a higher standard—and rightfully so.   

By outsourcing to a reputable radiology billing company, you can rest assured about clear documentation, trained coders, reliable tools, and strong compliance practices. Most third-party billing services offer all-inclusive RCM and specialty-specific billing. Hence, other practices, like physicians, DME suppliers, and SNFs, can also outsource billing for accuracy and cost-reduction.    

Finally, when billing is accurate, revenue is secure. When it's not, even the best care can go unpaid.
