Diagnostic Radiology Coding:

Risks Are Too High to Gamble With Radiology Revenue

With radiology claims under tighter OIG scrutiny, compliance is always your safest bet.

Radiology has faced compliance issues for years, according to Marianne Durling, MHA, RHIA, CPC, CCS, CDIP, CPCO, CIC, CDEI, AAPC Approved Instructor, in her HEALTHCON 2024 session “Don’t Gamble With Your Facility’s Radiology Revenue by Ignoring Radiology Compliance Issues.”

“No matter what you did, you got paid for it: It was not a big deal,” Durling said. Auditors didn’t really look at radiology, “but that’s all changed,” she continued. Auditors are now looking at both lab and radiology services. What used to be considered safe, comfortable income for radiology facilities and providers is now up for review.

Avoid gambling with your revenue stream and putting your practice at risk by reviewing recent government rulings, common compliance issues, and areas of risk to watch out for in radiology.

Review Recent OIG Findings

The Office of Inspector General (OIG) has been clamping down on radiology fraud and abuse. Recent million-dollar investigations and settlements include:

  • $85.5 million settlement: Cardiac Imaging, Inc. (CII) agreed to pay $75 million, and its CEO Sam Kancherlapalli agreed to $10,480,000, for allegedly paying referring cardiologists excessively to supervise PET scans between March 1, 2014, and May 31, 2023. Fees were paid for time when cardiologists weren’t present and services weren’t provided. The settlement resolved claims brought under the whistleblower provisions of the False Claims Act, where CII and Kancherlapalli knowingly caused false or fraudulent claims submission to federal healthcare programs, violating the anti-kickback statute and the Stark Law.
  • $3.1 million settlement: The Radiology Group and Lalaji paid this sum to the OIG after the United States-based radiologists admitted to not conducting meaningful and adequate review of radiology scan draft interpretations prepared by India-based contractors who were not licensed. They also allegedly submitted claims for reimbursement to federal healthcare programs in which the radiologist who reviewed and interpreted the imaging was not the person listed on the claim.
  • $6.5 million lawsuit: Between 2016 and 2019, Pennsylvania interventional radiologist James McGuckin, MD, and his practice allegedly submitted more than 500 false claims to Medicare for unnecessary vascular procedures, including angioplasty, atherectomy, and placement of stents. McGuckin is a repeat offender, having been sanctioned in several states in previous years for similar wrongdoing.

Adhere to Proper Billing Requirements

To be compliant with radiology billing requirements, you need:

  • A valid order,
  • Supervision and interpretation,
  • A written report, and
  • Images stored permanently in the patient record.

A valid order means the provider is credentialed, is allowed to place the order, and is properly entered and recognized in your billing system. To bill normal radiology services, all these things need to be present.

According to Durling, “When radiology has to be part of another service line’s procedure, we’ve got to really make sure we have people at the table discussing coding challenges, the billing challenges, the regulatory requirements so that they’re met.” For example, there’s a good chance that somebody in neurosurgery, pediatrics, or gastroenterology has no clue about what the radiology components are; they just know they are supposed to do radiology as part of the procedure.

When billing radiology services, you need to know modifier use when only part of a service is rendered, bundling rules, and what is included in the global package. Consider the following modifiers for proper billing:

  • Modifier 26 (Professional component): Append modifier 26 if you are just billing for the professional reading and interpretation.
  • Modifier TC (Technical component …): Append modifier TC if you are the facility or location that’s expensing the cost for the equipment and staff to perform the radiology service.
  • Global package: If you are addressing all components together, and it’s all being paid from one entity, bill the procedure code without a modifier.

Check the National Correct Coding Initiative (NCCI) Procedure-to-Procedure Edits, Medically Unlikely Edits (MUEs), and Add-on Code Edits to help ensure you are reporting correct coding combinations for reimbursement. “Make sure you’re aware of the NCCI edits and you understand the bundling rules,” Durling said, “because … a lot of services are bundled into another service.”

It’s not always easy to meet all four components of billing requirements. For example, there has been a trend in point-of-care ultrasound (POCUS) in some facilities. The downside to them is that “with point-of-care ultrasounds, you don’t necessarily get supervision and interpretation, and a lot of times images are not permanently stored somewhere,” Durling said. With a lot of new radiology services (i.e., POCUS), all billing requirements are forgotten, so you can’t bill for them.

Understand Precertification and Preauthorization

More preauthorization (pre-auth) requirements have been added for radiology services, not just for CTs and MRIs. Durling said, “We are seeing additional services that never required pre-auths needing pre-auths all of a sudden.”

Many providers were setting up acceptable use criteria (AUC) prior to COVID-19. “Then COVID hit,” said Durling, “and kind of threw it under the bus for a while.” She ensures that AUC will make a comeback because it ensures providers are ordering the appropriate radiology services.

Many high-volume radiology facilities pay radiologists to do “protocoling” the day before, which is where they look at all the orders coming up for the next day or two and ask themselves, “Does this study make sense to address the clinical indication/question?” They will then spend time changing and protocoling orders. AUC can help providers who don’t do a lot of necessary radiology orders, such as family medicine and internal medicine doctors. “AUC defines what tests are needed, what’s appropriate, and whether something else needs to be ordered prior to the imaging,” according to Durling.

Be cautious about using AUCs and product updates, however. You may have everything set up and then an update will come out that is not compliant. The AUC product contractors may try to push the updates on you even though they aren’t compliant and refuse to make changes to remedy the compliance issues. This puts your claims and healthcare organization at risk. “Please make sure that even after everything’s signed and done that somebody’s looking at those updates to make sure they are still compliant,” Durling warned.

Example: Durling had a physician group call and say they have been doing facet joint injections for the same group of patients for 10 to 20 years, and now the Centers for Medicare & Medicaid Services (CMS) is making them jump through hoops to get them paid, to the point that the physician group wants to make the patients self-pay out-of-pocket. According to Durling, the problem is the new rules are for new patients, and the new requirements don’t address patients who have been getting injections for years. “My suggestion was we dig back through medical records and find all the original diagnostic things that were done to qualify them the first go-round,” Durling said. “There were paper records somewhere, and that’s the best you can do for these patients to ensure the facet joint injections are still covered.”

Be proactive when you know there are payment or policy changes coming so you don’t have to find out the hard way — months after the fact — that you aren’t meeting pre-auth requirements. Talk with your payer relations group to see if new policy changes affect your specific contracts with commercial payers.

Learn About Other Risks and Audit Areas

There are other areas that are risky in terms of maintaining compliance or that the OIG is paying extra attention to, as well. They include:

  • Limited vs. complete: CPT® codes for ultrasound make the distinction between a “limited” and “complete” exam. When you report a complete exam, be sure all components are imaged and documented.
  • Intensity-modulated radiation therapy (IMRT): Recovery audit contractors (RACs) are auditing diagnostic and therapeutic radiology, and the most recent focus has been on IMRT.
  • Duplex scans: Targeted probe-and-educate auditors have been reviewing duplex scans.
  • Independent diagnostic testing facilities (IDTF): To be considered “independent,” Medicare coverage and payment policy rules for IDTFs “have a ton of hoops you have to jump through to qualify,” said Durling. You can only do diagnostic procedures, and it’s very limiting.
  • Nuclear medicine: Auditors are looking at billing compliance of ventilation-perfusion (VQ) scans, brain scans, and full body scans (similar to PET scans).
  • New technologies: These can include approved and non-approved devices and procedures that are not part of an approved trial or study. For example, if you are using the new CT-enhanced digital mammography and magnetic resonance-guided hi-intensity focused ultrasound (MRgHIFU) for essential tremor treatment, be sure you know the requirements, who and what you can bill, bundling rules, modifiers, etc.

Good resources to help bolster radiology claims compliance include professional medical societies for diagnostic radiology, such as the American Society of Radiology and American Society of Nuclear Cardiology.
