8 Medical Coding Mistakes That Can Cost You

Each step taken in medical coding can have a direct impact on the financial health of your healthcare organization. The precision of medical coding isn’t just about compliance; it’s a pivotal factor that determines the flow of revenue into a practice.

In this intricate dance of numbers and codes, even the smallest misstep can lead to significant setbacks. In this context, it’s crucial to be aware of  medical coding mistakes that can cost you, setting the stage for a discussion on the importance of accuracy and detail in medical coding practices.

4 Common Oversights in Medical Coding

1. Incorrect code usage: a common mistake involves using outdated or incorrect use applications of various code sets, namely CPT, ICD-10-Cm, and HCPS codes. EA Each code type serves a distinct purpose in the healthcare billing, and misunderstanding their use can lead to significant billing errors. This not only causes a delay in the payment process, but it also increases additional follow-up costs.

    • CPT Codes: These codes are integral for documenting medical, surgical, and diagnostic services. Using outdated or incorrect CPT codes for procedures can cause claim rejections, as these codes communicate the specific services provided to the patient. It’s essential to stay updated with the annual CPT code changes to ensure accurate billing.
    • ICD-10-CM Code: These codes are used for diagnosing and are crucial for indicating the medical necessity of the procedures performed. Incorrect or outdated ICD-10-CM codes can lead to denials, as they may not accurately reflect the patient’s condition, leading insurers to question the necessity of the treatment.
    • HCPCS Codes: Primarily used for products, supplies and certain services not covered by CPT codes. Incorrect HCPCS coding can result in unpaid claims for necessary medical equipment and supplies. Ensuring the correct HCPCS codes are used is vital for the reimbursement of these items and services.

2. Undercoding: To avoid audits or accusations of overcharging, some practices might undercode, which means not billing for all the services provided. This leads to a direct loss of revenue and can inadvertently signal to payers that the level of care provided was less complex than it actually was.

3. Upcoding: This mistake occurs when codes are used for more complex (and expensive) procedures than were actually performed. Upcoding can result in significant legal and financial consequences, including permanent exclusion from taking part in Medicare, fines and loss of provider credibility.

4. Lack of Specificity: Failing to use the most specific codes available can lead to claim denials. Specificity is crucial in medical coding not only to accurately represent the patient’s diagnosis and the services provided, but it is also required under the Health Insurance Portability and Accountability Act (HIPAA).

4 Uncommon Medical Coding Mistakes

  1. Misapplication of Global Surgery Rules: Global surgery packages are comprehensive, covering all necessary services typically provided around a surgical procedure, including pre-op, the surgery itself, and post-op care.

Each Medicare Administrative Contractor (MAC) may have specific guidelines that vary by state, affecting how these rules are applied. A common mistake is misunderstanding the extent of the global period, which for major surgeries typically spans 90 days and includes related Evaluation and Management (E/M) services. Incorrectly billing services that fall within this period can lead to improper claims submissions. 

  1. Overlooking Modifier Use: Modifiers are essential tools for providing clarity in medical coding, particularly when special circumstances apply. They can adjust the description of a procedure without altering its code, ensuring the precision of billing. 

The challenge arises in both the underuse and misuse of modifiers, which can significantly impact claim accuracy. This is especially true for CPT codes that denote “separate procedures,” where specific guidelines dictate when a service can be billed independently of related procedures.  

Level II Modifiers: Level II Modifiers, often referred to as HCPCS Level II alphanumeric codes (mentioned earlier), are used primarily to communicate with Medicare and other insurers about supplies, services, and certain procedures that are not covered by traditional CPT codes.  

These modifiers provide essential details that can affect reimbursement, such as whether an item was rented or purchased, or if a service was performed by a specialist in a specific field. 

A deep understanding of when and how to use these modifiers is paramount for denial management and the financial health of your organization. 

  1. Fragmented Billing: Sometimes, services that should be billed as a single comprehensive code are instead broken down and billed separately, a practice known as “unbundling” or split billing. This error can bypass critical claim edits and adjudication processes, potentially appearing fraudulent by payers and can lead to denials and audits. Recognizing when services are integral to one another and should be billed as a single entity is vital to prevent claim denials and potential audits.
  1. Ignoring LCDs and NCDs: Local Coverage Determinations (LCDs) and National Coverage Determinations (NCDs) provide crucial guidance on what services are covered under Medicare, with LCDs varying by region and MAC. Ignoring these determinations when coding can result in services being denied for not meeting medical necessity or coverage criteria.

National coverage determinations (NCDs) are established using an evidence-based procedure that allows for participation by the public. In certain circumstances, CMS’s research is supplemented by an outside technology review and/or consultation with the Medicare Evidence Development & Coverage Advisory Committee (MEDCAC). 

Understanding and addressing these less common coding mistakes requires an experienced approach, including a deep understanding of the specific guidelines set forth by different MACs and the intricacies of coding systems like CPT, HCPCS, and the application of modifiers. These complexities highlight the need for meticulous attention to coding practices to ensure accuracy, compliance, and optimal reimbursement.
