Don't Let Radiation Oncology Coding Errors Zap Your Revenue

Common Coding Mistakes in Radiation Oncology (And How to Avoid Them)


Radiation oncology coding and billing is nothing short of complex. 

 

It’s a process that requires systematic and structured review of the charge process to validate the necessity of treatment modalities, apply proper coding techniques, catch/prevent errors, ensure billing compliance, and optimize revenue. We’ve found a strong cause and effect relationship tied to quality assurance checks for proper coding that promotes—or hinders—the outcome of the revenue cycle. 

 

At Radformation, we’ve had the unique opportunity to work one-on-one with departments across the country, exploring their billing practices in depth. We’ve gained valuable insights by reviewing the varied approaches of our clinical partners, uncovering many common missteps in their process. It’s our pleasure to identify opportunities for process improvement and provide education and strategies to promote revenue integrity. Below is a compilation of the recommendations we’ve gleaned as a result of our conversations with clinics. 

 

Getting Direct 

The written directive outlines the plan of care for radiotherapy, providing a guide for the expected services during a course of radiation. This document is the compass for a patient’s course of treatment and dictates the services needed, preliminary medical necessity, and defined goals. It can also serve as a guide for authorization and coding when well documented. 

 

When reporting 77261-77263 codes represented in the clinical directive documentation, it’s crucial to understand that only one code is applicable for the patient’s entire course of therapy. That’s the case even if multiple treatment sites are present, combined modalities are necessary, or significant changes occur through the entire course of radiotherapy. Almost all questions related to coding and billing require review of this documentation to determine the intent and plans for care. This is the best place to start, because if we can’t get this documentation right, it’s all downhill from here!

 

Why is Documentation So Important? 

The absence of documentation can make it hard to demonstrate that any given service was actually required or ever completed. This can be the most common risk of compliance in all service lines and can lead to poor revenue outcomes for all general and specialty medical services. According to recent data from the Centers for Medicare & Medicaid Services (CMS), it’s obvious that we’ve got work to do as it pertains to documentation.

 

CMS runs an audit of all its claims each year to estimate the number of  improper payments via their Comprehensive Error Rate Testing (CERT) program. Each year, they review a stratified random sample of fee-for-service claims to determine if they were paid properly under Medicare coverage, coding, and payment rules. The 2023 Medicare FFS estimated improper payment rate was a staggering 36% for radiation oncology, representing $330M in improper payments.

In our experience, we’ve seen similar issues with documentation misses and errors with the departments we partner with. Whether it’s a missing document, the documentation lacks a physician signature or timestamp, or the proper date of service and supporting information is missing, failing documentation puts facilities at risk of non-compliance and payer revenue recovery. What’s your process for preventing this risk?

 

The Claim Paid So It Must Be Right! 

Is receiving a payment for services a guarantee? The answer is NO! 

 

Payment for services can be reviewed or audited for any reason, at any time. Without consistent claim review to ensure proper coding and billing, you may be at risk even if you’ve already received payment. Like departments, at times even payers make mistakes, and they have teams in place to recoup their payments when this occurs.

 

Common Mistakes Seen That Can Delay Payment or Lead to Payment Losses: 

  • Diagnosis codes that do not meet medical necessity according to national, regional, state, or payer guidelines. 
  • Improper payment of Correct Coding Initiative (CCI) edits due to service bundling.
  • Lack of documentation—or errors in documentation—found during payer audit or request for documentation.
  • Improper authorization for complex or higher service modalities.
  • Patient complaint for services or lack of understanding the codes or services reported to payers.
  • Lack of self auditing or understanding of the revenue process.

Charge Audits

The best way to prevent errors in billing is to periodically evaluate internal standards on a full episode of care performed by physicians and medical staff. Performing billing audits is crucial for protecting revenue and compliance by identifying coding, billing, and documentation problems before a payer does. 

There are several ways to go about this quality assurance for billing, including leveraging the expertise of a third party company or consultant, performing a self-audit (either manually or using software), or securing software or analytics programs to perform an audit. The findings of an audit can validate standard operating procedures, identifying coding mistakes and issues, performing documentation checks, and improving revenue integrity. A comprehensive audit should include a proper evaluation of the following departmental operations:

  • Scheduling and appointments, record completion, date validation

  • Verify and review all documentation for services
    • Evaluation and intent for treatment
    • Diagnosis codes and medical necessity 
    • Proof of service delivery
    • Proper supporting documentation for care provided
    • Validate signatures, date, and time stamp
  • Charge capture process
    • Verify charge activity
    • Validate appropriate code against documentation
    • Check for charge export or push to the billing system
  • Coding edits or scrubs
    • Verify any stops or reviews required prior to claim submission
  • Verification of claim submission or review transmittal reports from the clearinghouse to identify shortfalls. 

  • Review of the electronic official benefits statement should be evaluated in the efforts of a self audit. 

  • Tracking billing trends including
    • Statistical payment data
    • Denials
    • Voided and Corrected Claims
    • Accounts Receivable

The outcome of an audit identifies gaps, errors, and risks which are difficult to appreciate from day to day operations. The process reinforces and promotes the accountability of each member of the treatment team, enhances optimal reimbursement, and reduces compliance risks.

Common Coding Flops

Through helping departments perform coding audits with QuickCode, we’ve seen it all. While some errors are unique, we frequently see the same issues crop up at multiple institutions. Here are a few common coding misses and opportunities for improvement:

  • The radiation therapy plan defined as either a simple treatment plan (77261), an intermediate treatment plan (77262), and a complex treatment plan (77263) documents the written directive and goals for treatment.

    This code is commonly missed because it often may not be tied to a direct face-to-face encounter with the physician or clinic or lacks consistency when it’s reported. Consider the best option for your department and establish a safeguard for reporting! 

  • Immobilization devices (77332, 77333, or 77334) created during a patient’s initial simulation appointment are a common miss due to lack of order, documentation, definition, or understanding of what’s being used to immobilize the patient. Missing these opportunities can have a large impact on facilities because the devices have associated costs and reimbursement is needed to assist with these costs. 

  • Radiotherapy treatment planning charges for lower modalities such as electron planning (77321), simple isodose planning (77306), or complex isodose planning (77307) show a higher rate of error compared to other planning techniques used in facilities. Errors are common for these planning techniques due to a lack of standardization for planning processes and understanding of their guidelines, lack of documentation or conditions necessary to support these charges, and improperly reported or missed codes at the time of the charge capture. 

  • Common radiotherapy coding misses can be seen for special services including the special treatment procedure (77470), special physics consultation (77370), respiratory management simulation add-on service (77293), respiratory gating or DIBH associated with daily treatment delivery (G6017 or 77387). Often these services deviate from the standard episode of care, require special documentation, and may not have a designated person to capture the service. 

  • Treatment planning charges, from the initial and boost plans to necessary replans, frequently give departments trouble. These range from basic dosimetry calculations (77300) to  treatment devices including 77334 or 77338. The most common reason these codes are missed is the lack of standardized processes, error in charge capture, error in prescription or documentation, or understanding the necessity of these codes for the initial episode of care or a change within the episode of care. 

  • Finally, physician weekly treatment management codes (77427, 77431, 77432, and 77435) and the physics weekly management (77336) codes are sore spots for some. This coding process requires a strong level of nuanced understanding of billing standards that involve complex scheduling, documentation, and timing considerations. 

Individually, These errors may seem small but the effects are huge in clinics everywhere! It is highly recommended for facilities to establish standard operating procedures related to planning processes to include the validation and process for review to prevent these costly misses or errors. Consider these misses when reviewing daily charges, performing month end checks, or auditing the patient’s codes and documentation as part of the final treatment process.
