In the world of medical billing, there are various modifiers used to describe specific circumstances surrounding a healthcare service or procedure. One of the most commonly used, yet often misunderstood modifiers, is Modifier 59. This simple two-digit code can significantly impact the reimbursement process and help avoid claim denials and improper payments. In this blog, we will demystify Modifier 59 and provide clear guidance on its appropriate use to ensure accurate medical billing practices.
Understanding Modifier 59
Modifier 59 is classified as a "Distinct Procedural Service" modifier by the Centers for Medicare and Medicaid Services (CMS) and the American Medical Association (AMA). Its purpose is to identify and separate services or procedures that are distinct from others provided during the same encounter. Essentially, it indicates that two procedures that are usually bundled together should be paid separately when specific criteria are met.
When to Use Modifier 59
The use of Modifier 59 should adhere to specific guidelines to prevent potential misuse or abuse, which could lead to claim denials or even fraud accusations. CMS and AMA have outlined some essential principles for using Modifier 59 appropriately:
Different Anatomical Sites: When two procedures are performed on different anatomical sites or organs, Modifier 59 can be used to indicate that they are distinct and separate services. The documentation should clearly demonstrate that the procedures were performed at unrelated sites to justify the use of this modifier.
Different Sessions: If two procedures are performed during different patient encounters on the same day, Modifier 59 can be applied to indicate that they are separate services and not part of the same treatment session.
Different Incidents: Modifier 59 may be used when two procedures are performed during the same encounter but are not typically reported together due to different diagnoses or injuries.
Staged Procedures: When a procedure is planned to be performed in multiple stages, Modifier 59 may be necessary to indicate that each stage is distinct and separate from the others.
Different Procedure Codes: Modifier 59 should be used when there is no other suitable modifier available to describe the relationship between two procedures.
Common Misuse of Modifier 59
Unfortunately, Modifier 59 is often misused, leading to compliance issues and claim denials. Some common pitfalls to avoid include:
Unbundling: Using Modifier 59 to unbundle procedures that are considered part of a comprehensive service can lead to overbilling and may be considered fraudulent.
Routine Use: Avoid using Modifier 59 routinely as a default modifier. It should only be utilized when other specific modifiers do not accurately describe the circumstances.
NCCI Edit Overrides: Do not use Modifier 59 solely to bypass National Correct Coding Initiative (NCCI) edits without proper documentation justifying its use.
CMS and AMA Guidelines
The CMS and AMA have provided additional guidelines to ensure proper usage of Modifier 59:
NCCI Edits: Always review the National Correct Coding Initiative (NCCI) edits before applying Modifier 59. If the edit allows for a more specific modifier, such as X(EPSU) modifiers, use them instead to describe the relationship between the procedures.
Documentation: Accurate and detailed documentation is crucial when using Modifier 59. It should clearly demonstrate the medical necessity and rationale for the separate and distinct procedures.
Use of Modifiers X(EPSU): In some cases, CMS and AMA have introduced more specific modifiers, known as X(EPSU) modifiers, to replace Modifier 59 for certain scenarios. These X(EPSU) modifiers provide a clearer description of the circumstances for the separate services and should be used when applicable.
Appeals Process: If a claim with Modifier 59 is denied, follow the appeals process to provide additional documentation and clarification supporting the appropriate use of the modifier.
Best Practices for Correct Use
To ensure compliant and accurate medical billing, consider the following best practices:
Education and Training: Conduct regular education and training sessions for coding and billing staff to keep them updated on the latest CMS and AMA guidelines regarding Modifier 59.
Review and Audit: Perform periodic reviews and audits of claims with Modifier 59 to identify any patterns of misuse and rectify them promptly.
EHR Support: Leverage electronic health record (EHR) systems that offer prompts and alerts to guide coders in selecting the appropriate modifiers.
Consulting with Experts: Seek advice from experienced medical billing experts or consultants to clarify any doubts or complex scenarios related to Modifier 59.
