Common Medical Coding & Billing Mistakes: Unbundling Coding, Misinterpreting Guidelines & More

Accurate medical coding is the linchpin that connects patient care to financial reimbursement. Yet, even the most experienced medical coder can fall victim to errors. These mistakes, while seemingly minor, can have a significant ripple effect, impacting not only a healthcare organization’s financial health but also patient care and overall industry efficiency.

In this article, we delve into the most common medical coding mistakes we see in the industry as coding consultants, we explore the financial ramifications we see in healthcare organizations, and provide actionable strategies for preventing these errors. By understanding these pitfalls and implementing robust safeguards, we see a great improvement on how our healthcare partners can ensure accurate coding, optimize revenue streams, and prioritize patient well-being.

Unveiling the Culprits: Common Medical Coding & Billing Mistakes

1. Inaccurate Coding: This encompasses a range of mistakes, including selecting the wrong code for a procedure or diagnosis, missing essential details (laterality, severity, etc.), unbundling codes, or failing to capture the highest level of specificity. It is important to utilize a single code that encompasses payment for all the component parts of a procedure. Unbundling occurs when a coder uses multiple CPT codes for the separate parts of the procedure, either intentionally or from a misunderstanding. Inaccurate coding can lead to undercoding, where reimbursement falls short of the actual service provided, or upcoding, where a more complex code is used than warranted. Both scenarios create financial discrepancies and potential audits.
2. Incomplete Documentation: Incomplete physician notes are a major culprit behind medical coding errors. Without clear documentation detailing diagnoses, procedures, and treatment plans, coders lack the necessary information to assign accurate codes. This can lead to denials, delays, and the need for rework. When details of the patient visit are missing in the documentation, we have to put the encounter on hold and send a physician query, which we’ve seen lead to delayed reimbursements and a high DNFB rate.
3. Outdated Coding Systems: The healthcare landscape is constantly evolving, with new procedures, diagnoses, and coding guidelines emerging regularly. Failure to update coding systems with the latest versions of CPT and ICD-10 codes can result in inaccurate coding and missed opportunities for capturing appropriate reimbursement. We’ve seen how long it can take health systems to implement system updates. We recommend HIM professionals review the applicable Coding Clinic and CPT Assistant advice for the most current, accurate coding guidelines. Additionally, external coding education vendors, like YES, offer ongoing education on the updates. It’s critical that coders and auditors familiarize themselves with the updates ahead of time if the system isn’t updated yet.
4. Misinterpreting Payor Billing Guidelines, Modifiers, POS Codes, LCD/NCDs: Modifiers provide additional details about a service performed, impacting reimbursement. Incorrect modifier usage, such as neglecting to include a modifier for a repeated procedure or an unusual presentation, can significantly impact claim accuracy. We’ve seen firsthand how our clients’ misinterpretations of payer modifier guidelines, as well as changes to how modifiers are billed, led to errors and denied claims. Modifier guidelines frequently change, especially as the healthcare industry evolves. The most recent policy changes have affected telehealth services and Place of Service (POS) requirements. It’s important that HIM professionals continuously review payer modifier and medical necessity guidelines to ensure the encounter is coded accurately.
5. Lack of Communication: Inadequate communication between coders, providers, and other healthcare professionals can lead to misunderstandings and inaccurate coding. Regular communication channels and clear documentation practices are essential for ensuring everyone is on the same page. For one client, our team created a standardized template for physician queries. By analyzing the client’s inpatient severe malnutrition cases over a period of three years, we were able to develop and implement a standardized severe malnutrition review form template for inpatient coders. This allowed them to submit their documentation findings to the hospital’s Physician Advisor efficiently. Additionally, the case study helped identify educational opportunities for the consistent use of the ICD-10 code for severe protein-calorie malnutrition diagnoses.

The Price of Medical Coding Mistakes: Financial Repercussions for Healthcare Organizations

Medical coding errors carry a hefty financial burden for healthcare organizations. Here’s how these errors can impact the bottom line:

• Reduced Reimbursement: Undercoding leads to missed revenue opportunities. Conversely, upcoding can trigger audits and potential penalties if discrepancies are discovered.
• Increased Administrative Costs: Correcting coding errors requires additional staff time and resources, diverting valuable resources from other areas.
• Delayed Payments: Incorrect claims lead to claim denials and delays, which impact cash flow and create financial strain.

In addition, the repercussions of medical coding mistakes extend far beyond the financial realm. Inaccurate coding can lead to:

• Potential for Fraud Investigations and Regulatory Penalties: Repeated, deliberate coding errors can raise red flags and trigger investigations by insurance companies or regulatory agencies, leading to increased scrutiny and potential penalties.
• Delayed or Denied Treatment: Denials due to coding errors can delay or deny patients access to necessary treatment, impacting their health outcomes.
• Inefficient Healthcare Resource Allocation: Inaccurate coding can distort data on healthcare resource utilization, hindering efficient resource allocation and impacting patient care quality.

Safeguarding Your Revenue: Strategies for Preventing Medical Coding & Billing Mistakes

Combating medical coding mistakes requires a multi-pronged approach. Here are some key strategies to consider:

• Invest in Ongoing Coder Education: Regular training on the latest coding guidelines, including CPT and ICD-10 updates, is crucial for maintaining accuracy.
• Implement Robust Auditing Practices: Regular audits of coded claims by qualified professionals can identify and rectify errors before they impact reimbursement. Audits have the power to improve coding quality.
• Standardize Documentation Practices: Develop clear templates and guidelines for physician documentation, consistently capturing all necessary details.
• Utilize Coding Software with Error-Checking Features: Advanced coding software can highlight potential coding errors based on pre-programmed rules and logic.
• Foster Open Communication: Establish clear communication channels between coders, physicians, and other staff to promptly address uncertainties and resolve coding discrepancies.
• Invest in Coder Certification: Certified coders have demonstrated a thorough understanding of coding principles and best practices, reducing the risk of errors.

Prioritizing Accuracy for Optimal Performance

Medical coding errors are a persistent challenge in the healthcare industry. However, by implementing the strategies outlined above, healthcare organizations can significantly reduce errors and safeguard their financial health. Remember, accurate coding isn’t just about the bottom line; it’s about ensuring patients receive the appropriate care, resources are allocated efficiently, and the industry functions optimally. By prioritizing accuracy, healthcare organizations can foster a culture of quality, optimize revenue streams, and contribute to a more efficient and effective healthcare system for all.
