Mastering Modifiers: Using Modifier 25 and Modifier 59 together for Accurate Billing

modifier 25 and modifier 59

The medical billing field is not easy as the billing is not just about the simple numbers instead complicated codes and modifiers are included in it. Each code is different for each claim and knowing which one is accurate for the provided service is a difficult task. These codes vary from payer to payer. That’s why it is a difficult task to manage these codes and modifiers. Among those modifiers, Modifier 25 and Modifier 59 are very important to differentiate separate services. But people get confused in those modifiers which causes denial of claim. This misconception is caused by the similarities between the two modifiers. 

In the CPT code, both modifiers show two different services that are billed on the same date of services but not billed together. This sets them apart from each other. Both of these modifiers are almost the same but are different. And to know the difference between both of these modifiers is very crucial. So let’s see when and how to use modifiers 25 and 59 to reduce your billing mistakes.

What is Modifier 25?

The modifier 25 means “Significant, Separately Identifiable Evaluation and Management Service by the Same Physician or Other Qualified Healthcare Provider on the Same Day of the Procedure or Other Service.” An Evaluation and Management (E/M) code can have this modification added to it to show that the E/M service that was rendered on the same day as another operation was separate and essential. 

Key Points of Modifier 25:

E/M Service: Modifier 25 is only used with E/M codes.

Same Provider, Same Day: This modification applies when the same provider conducts both the E/M service and another operation on the same day.

Significant and Separate: The E/M service must be significant and needs to be identified separately from the procedure performed.

Misuse of Modifier 25

One of the common errors in using Modifier 25 is appending it to non-E/M codes or when the E/M service is not significantly distinct from the procedure. You need to avoid it by ensuring that the E/M service is substantial and separately identifiable. Moreover, do not use Modifier 25 for procedures without a distinct E/M service.

Modifier 59:

Modifier 59 shows a distinct procedural service code. It is specifically designed to indicate that different services are provided to the patient on the same day and are separate from each other during the same session. This modifier is used to bill a pair of codes that cannot be billed together. This modifier helps to prevent bundling and ensures that separate procedures are recognized and reimbursed correctly. If you do not include the right modifier your services will be reimbursed for one of the procedures by the payer. The reason is that the payer will assume that one of the services was built into the other. 

Key Points of Modifier 59:

Non-E/M Codes: Modifier 59 is applied to procedural codes that are not E/M.

Unique Service: The process needs to be unique from other services that are offered that day.

Preventing Incorrect Bundling: Modifier 59 is essential for eliminating the improper bundling of services that need to be billed individually.

When to Use Modifier 59?

  • If you are a healthcare provider then you must use a modifier in the following conditions. 
  • If you bill for two different services that form an NCCI edit pair and provide services that are separate from each other. 
  • In the documentation, you must enlist that you performed those services independently that are different from each other.

Examples of Modifier 59 Usage

Distinct Procedural Services: Modifier 59 should be used to indicate that therapeutic exercise (97110) and manual therapy (97140) provided by a therapist to the same patient on the same day were independent and individually identifiable treatments. 

Avoiding Bundling: Modifier 59 ensures that neuromuscular re-education (97112) and gait training (97116) are provided separately and that each is valued for the unique function it plays in the patient’s treatment strategy. 

Misuse of Modifier 59

A common misuse of modifier 59 is to get around Correct Coding Initiative (CCI) modifications, which might result in audits or rejections. Use Modifier 59 only when methods are genuinely unique and independent to avoid abuse. Services that should be bundled in accordance with CCI modifications should not be unbundled using Modifier 59. 

When to Use Modifier 25 and Modifier 59 Together

If you are thinking about using modifiers 25 and 59 together then yes it is possible. But there are some unique scenarios in which you can use both concurrently, such as when a patient receives a significant, separately identifiable E/M service and many procedural services on the same day. For example, if a patient visits for the purpose of a full check-up (E/M service) and also needs a minor surgical treatment, here both modifiers will be applied to ensure correct billing.

Example:

A patient comes with symptoms that necessitate a thorough assessment and management service (E/M). During the same appointment, the clinician will perform a small surgical procedure.

  • Modifier 25 is added to the E/M code to represent a major and separate identified service.
  • Modifier 59 is added to the procedural code to differentiate it from the other procedural services performed that day.  

Documentation Requirements

When employing Modifiers 25 and 59 together, certain documentation criteria must be met to guarantee accurate and detailed documentation. The medical record must clearly reflect the separate nature of the services provided. This includes: 

E/M Documentation: Clearly document the patient’s history, examination, and medical decision-making process.

Procedure Documentation: Write down the characteristics of the procedure, including its need and distinction from the E/M service.

Best Practices for Using Modifiers 25 and 59

Here are some guidelines that you must adopt when using modifiers 25 and 59. 

  • Regularly review and update your knowledge of the Current Procedural Terminology (CPT) and CCI guidelines. Changes in coding rules can impact the correct use of modifiers, so it is important for you to stay informed.  
  • Then another crucial factor is your billing staff. Make sure that your billing team is well-trained and understands the proper use of modifiers. You can improve this more by arranging regular training sessions and keeping them updated. This practice helps to reduce errors and improve billing accuracy. 
  • Auditing is very important in billing processes. So, you must conduct regular audits of your billing methods to identify and fix any misuse of modifiers. Audits also help to maintain compliance and avoid potential payer denials or audits.
  • After that focus on the importance of detailed documentation. Accurate and specific documentation supports the use of modifiers and ensures that claims are substantiated.

Frequently Asked Questions

Modifier 25 is a CPT code modifier used to indicate that an Evaluation and Management (E/M) service provided on the same day as another procedure was significant and separately identifiable from the procedure.

Modification 59 is a CPT code modification that indicates that a treatment or service was unique or independent of other services conducted on the same day, ensuring that different operations are appropriately identified and reimbursed. 

Modifier 25 should be used when an E/M service is provided on the same day as another procedure and the E/M service is significant and separately identifiable from the procedure.

Modifier 59 should be used when two services that form an NCCI edit pair are provided independently from one another. It indicates that the services are distinct and should not be bundled together.

Yes, Modifier 25 and Modifier 59 can be used together when a patient receives a significant, separately identifiable E/M service, and distinct procedural services on the same day. But remember that using these modifiers together requires proper documentation.
