Do you add modifier 59 to add on codes when filling out medical billing forms? If you’re not sure, you’re not alone. Many people in the healthcare world are confused about whether or not to use this modifier. It’s a question that can lead to lots of head scratching and double-checking before hitting the submit button. In this article, we’ll explore this topic in depth and give you the answers you need to put your mind at ease.
Billing and coding can be complicated and confusing, even for people with years of experience. Code modifiers, in particular, can cause headaches for those who are not familiar with all the ins and outs of medical billing. The use of modifier 59, in particular, has been a topic of debate in recent years. It’s a necessary tool in certain situations, but it’s not always clear when it’s appropriate to use. That’s why we’re going to delve into what modifier 59 is, when it’s appropriate to use it, and the consequences of using it incorrectly.
We’ll also cover some common scenarios where you may need to use modifier 59. For example, if a patient receives two services during the same visit that are normally considered to be bundled into one payment, you may need to use modifier 59. The modifier indicates that the services are distinct and separate, meaning that both should be paid for. Similarly, if a patient requires two procedures that are normally not performed together, modifier 59 may be necessary to indicate that both are necessary for proper treatment. So, if you’re unsure whether to use modifier 59 or not, this article is for you.
Correct Use of Modifier 59
Modifier 59 is a common modifier used in medical billing and coding to distinguish between procedures or services that are normally bundled together but are performed separately on the same day. It’s a tool that ensures accurate billing and prevents duplicate payments for services that should only be billed once.
However, the use of modifier 59 has been a source of confusion and errors for many medical coders and billers. It’s important to have a clear understanding of when and how to use modifier 59 to avoid denials and ensure compliance with coding regulations.
Guidelines for Using Modifier 59
- Modifier 59 should only be used to indicate that a procedure or service was distinct or independent from other services performed on the same day. It should not be used to bypass bundling edits or to indicate a different site or organ system.
- It’s important to provide documentation that supports the use of modifier 59, such as notes showing a different session, separate injury, or different anatomical site.
- If a more appropriate modifier exists, such as modifier 51 for multiple procedures or modifier 25 for significant, separately identifiable evaluation and management (E/M) service, it should be used instead of modifier 59.
Examples of Correct Use of Modifier 59
The following are examples of situations where modifier 59 would be appropriately used:
- A patient undergoes a knee arthroscopy and a separate ankle arthroscopy on the same day
- A patient receives a screening mammogram and a diagnostic mammogram on the same day due to a suspicious lump
Modifier 59 and NCCI Edits
The National Correct Coding Initiative (NCCI) implements bundling edits to prevent billing of services that are typically performed together as part of a larger procedure. Modifier 59 can override these edits and allow for separate payment of the services.
| Modifier | Description |
|---|---|
| Modifier 59 | Distinct procedural service |
| Modifier 51 | Multiple procedures |
| Modifier 25 | Significant, separately identifiable E/M service |
However, the use of modifier 59 with NCCI edits requires careful consideration and documentation. The Centers for Medicare and Medicaid Services (CMS) recommends that billing professionals use modifier 59 sparingly and only when necessary.
What are add-on codes?
Add-on codes are supplemental codes that healthcare providers use to complement the main service or procedure. These codes are often added when a second, complementary service is provided in conjunction with the main service. Add-on codes cannot be used alone and must be reported with a primary code. These codes are identified by the symbol “+”, and payment is usually based on the bundling adjudication process. It is important to remember that add-on codes are not always reimbursed separately when reported with the primary procedure unless the modifier 59 is added.
When to use modifier 59 with add-on codes
- Distinct procedural Service: This modifier is used to identify services that are separate and distinct from other procedures or services performed on the same day.
- Same procedural Family: This modifier is used when the add-on code is from the same procedural family as the primary code and is typically used when multiple procedures are performed on the same day.
- Multiple procedures: This modifier is used when multiple procedures are performed during the same session by the same healthcare provider.
Why use modifier 59 with add-on codes
Modifier 59 establishes that a service or procedure was distinct or independent and not necessarily a part of the initial service. It identifies that the service was performed separately from the primary service and should be paid separately. Since the concept of add-on codes is relatively new, additions to the codes are still repetitive or included in the main procedure’s payment. In such cases, modifier 59 becomes necessary when the add-on code is distinct or independent of the main procedure and should be paid separately.
Summary Table of modifier 59 with add-on codes
| Modifier 59 | Description | Usage |
|---|---|---|
| Distinct procedural service | To identify distinct services performed on the same day | When a procedure is separate and distinct from other procedures or services performed on the same day |
| Same procedural family | To identify distinct services in the same procedural family | When the add-on code is from the same procedural family as the primary code |
| Multiple procedures | To identify separate multiple procedures performed in one session by the same provider | When multiple procedures are performed during the same session by the same healthcare provider |
In conclusion, when add-on codes are used in conjunction with primary codes, the use of modifier 59 may be necessary to receive proper reimbursement. This modifier helps to identify independent and distinct services that should be paid separately. Healthcare providers should ensure they understand the proper use of modifier 59 to ensure accurate billing and avoid potential audit risks.
Common Coding Errors Related to Modifier 59
Modifier 59 is one of the most used modifiers in medical billing and coding. It is used to indicate that a procedure or service is different from other procedures or services performed on the same day. However, improper use of modifier 59 can lead to coding errors and potential denials. Here are some common coding errors related to modifier 59:
Errors in Identifying Distinct Procedural Services
- Using modifier 59 instead of a more specific modifier
- Using modifier 59 when a more specific anatomical modifier should be used
- Using modifier 59 to bypass National Correct Coding Initiative (NCCI) edits
One of the main reasons for coding errors related to modifier 59 is the failure to properly identify distinct procedural services. Modifier 59 should only be used when no other more specific modifier is available to accurately describe the service performed. If a more specific modifier exists, it should be used instead. Additionally, using modifier 59 to bypass NCCI edits is not appropriate and may lead to claim denials.
Errors in Documentation
Another common coding error related to modifier 59 is insufficient documentation. Providers must document the distinct procedural service and the reason why it was necessary to perform the service separately from other services on the same day. If documentation does not support the use of modifier 59, the claim may be denied.
Errors in Billing
Finally, billing errors can lead to improper use of modifier 59. One common error is using modifier 59 for add-on codes that do not require it. Add-on codes should not be reported with modifier 59 unless they meet the specific criteria for its use. Additionally, using modifier 59 on multiple line items on the same claim without proper documentation may lead to claim denials.
| Scenario | Correct Coding | Incorrect Coding |
|---|---|---|
| Two codes describe different procedures, performed on the same day, at different anatomical sites | Modifier 59 appended to one of the codes | None |
| Two codes describe different procedures, performed on the same day, at the same anatomical site | Additional anatomical modifier(s) appended to the codes | Modifier 59 appended to one of the codes |
| Two codes describe a procedure and a separate, distinct service, performed on the same day | Modifier 59 appended to the separately reportable code | Modifier 59 appended to both codes or none appended to either code |
Proper use of modifier 59 is critical to accurate medical billing and coding. Providers and billing staff must ensure that the modifier is used appropriately and with sufficient documentation. By avoiding common coding errors related to modifier 59, claim denials and delays can be minimized, leading to more efficient and effective healthcare services.
When to use modifier 59 with add-on codes?
If you are in the medical billing industry, you know that it can be complicated and challenging to navigate all the rules and guidelines to bill correctly. The proper use of modifiers can significantly impact your claims’ success and ensure that you get proper reimbursement for your services. Modifier 59 is one of the most used modifiers when billing add-on codes. Here is what you need to know about using modifier 59:
- When you perform multiple procedures on the same day, the provider must select the primary procedure code and add additional service codes using add-on codes. However, if the procedures have a mutually exclusive edit or are not typically performed at the same session or anatomical site, you must use modifier 59 to unbundle the codes.
- Modifier 59 should only be used when no other appropriate modifier fits the service’s circumstances. Providers must ensure that they understand the modifiers’ definitions to avoid using the wrong modifier or misrepresenting the service provided.
- The use of modifier 59 should be rare and used only when necessary. Providers who overuse modifier 59 may experience increased scrutiny over their claims, leading to audits and delays in payment.
If you need to use modifier 59, here are some best practices to follow:
- Make sure that the documentation supports the use of modifier 59 to unbundle the codes.
- Use the most specific and appropriate CPT code for the service provided. Do not use a generic code or a code that may overlap with other codes.
- Educate your staff and providers on the proper use of modifier 59 and any other modifiers that apply to their services. A lack of knowledge and understanding of modifiers could lead to the misuse of the modifier.
Examples of when to use modifier 59 with add-on codes
Here are some examples of when it may be appropriate to use modifier 59 with add-on codes:
| Procedure | Code | Modifier 59 Scenario |
|---|---|---|
| Bilateral ear tubes insertion | 69436 | 69210 (unilateral ear exam with modifier 59) |
| Excision of a benign lesion on the arm measuring 3.5 cm x 2.5 cm | 11403 | 11402 (excision of a benign lesion measuring 1.1 to 2.0 cm with modifier 59) |
| Diagnostic colonoscopy with polypectomy | 45385 | 45380 (colonoscopy with biopsy with modifier 59) |
These are just a few examples. Be sure to check with the payer for specific guidelines and documentation requirements. In summary, proper documentation and coding practices are essential for ensuring accurate reimbursement and avoiding potential billing errors and audits. Make sure your staff and providers understand the proper use of modifiers, especially modifier 59, to reduce the risk of denials and delays in payment.
Guidelines for using modifier 59 with add-on codes
Modifier 59 is often used to indicate that a procedure or service was distinct or independent from other services performed on the same day. When used with add-on codes, there are specific guidelines to follow to ensure accurate billing and coding. Here are some key points to keep in mind:
- Modifier 59 should only be used if no other modifier more accurately describes the relationship between the procedures.
- Modifier 59 should only be used when the procedures or services are performed during the same session or encounter.
- Modifier 59 should only be used when the procedures or services are not considered a component of another procedure or service.
It’s important to note that improper use of modifier 59 can result in denied claims and potential audit scrutiny. Make sure to carefully review the applicable billing and coding guidelines before using this modifier with add-on codes.
Examples of when to use modifier 59 with add-on codes
Here are some examples of situations where modifier 59 may be appropriate when using add-on codes:
- A patient with two lacerations on the same arm requires repair. The physician performs a complex repair on the larger laceration and a simple repair on the smaller laceration. In this case, modifier 59 should be used with the add-on code for the simple repair to indicate that it was a distinct service from the complex repair.
- A patient with a history of breast cancer requires a mammogram and breast ultrasound during the same encounter. Both services are performed and billed separately with add-on codes, and modifier 59 is used to indicate that they were separate and distinct services.
Common errors when using modifier 59 with add-on codes
Despite clear guidelines for using modifier 59 with add-on codes, there are still common errors that can lead to denied claims or other issues. Some of these errors include:
- Using modifier 59 when another modifier more accurately describes the relationship between the procedures.
- Using modifier 59 when the procedures or services are considered a component of another procedure or service.
- Using modifier 59 when the procedures or services are not performed during the same session or encounter.
To avoid these errors, it’s important to carefully review the billing and coding guidelines and ensure that modifier 59 is only used when appropriate.
Modifier 59 and NCCI edits
The National Correct Coding Initiative (NCCI) maintains a list of codes that are considered mutually exclusive. This means that the codes cannot be billed together unless there is a specific reason to do so. Modifier 59 can be used to override some NCCI edits, but only when specific criteria are met. The NCCI manual includes guidelines for using modifier 59 with NCCI edits, so it’s important to review these guidelines carefully if you are using this modifier with add-on codes.
| Criteria for using modifier 59 with NCCI edits: | Examples of when modifier 59 can be used to override NCCI edits: |
|---|---|
| The procedures or services are distinctly different. | Injection of a therapeutic agent and a diagnostic injection are performed at the same session. |
| The procedures or services are performed at different anatomic sites. | A CT scan of the cervical spine and a CT scan of the brain are performed during the same session. |
| The procedures or services are performed by different practitioners. | A physician performs a biopsy and a pathologist performs a separate interpretation of the biopsy tissue. |
Remember to follow NCCI guidelines carefully when using modifier 59 to override edits, and ensure that all criteria are met before submitting a claim with this modifier.
Impact of Incorrect Modifier Use on Reimbursement
When it comes to medical billing, proper use of modifiers is crucial to ensure accurate reimbursement. Incorrect use of modifiers can lead to claim denials or reduce the amount of reimbursement received. Here we’ll focus on the impact of incorrect use of modifier 59 on reimbursement.
- Denial of Claims: When modifier 59 is used incorrectly on add-on codes, it can lead to claim denials. This can result in loss of revenue, increased workload for the billing department, and delayed payments. Claims may be denied due to the lack of proper documentation, incorrect coding, or misuse of modifiers.
- Reduced Reimbursement: Incorrect use of modifier 59 on add-on codes can also result in reduced reimbursements. This is because the Centers for Medicare & Medicaid Services (CMS) and other payers have established rules for the use of modifiers that impact reimbursement. If modifiers are used incorrectly, the amount of reimbursement could be lower than expected.
- Audit Risk: Misuse of modifier 59 can also increase the risk of audits. When a high volume of modifier 59 is used, it raises a red flag for auditors who may scrutinize each code billed with modifier 59. This can lead to additional workload and stress for the billing team and impact the provider’s reputation.
Examples of Incorrect Modifier 59 Use on Add-On Codes
Below are some examples of incorrect use of modifier 59 on add-on codes:
| Incorrect Modifier Use | Correct Modifier Use |
|---|---|
| Adding modifier 59 to a code that is already bundled into another code | Using a more specific modifier instead of modifier 59, or not using a modifier at all if the code is not billable separately |
| Using modifier 59 on add-on codes that describe different aspects of the same service | Using a more specific modifier that accurately describes the service performed |
| Using modifier 59 when there is a more specific modifier available | Using the more specific modifier that accurately describes the service performed |
It’s important to accurately document and code each service provided to avoid claim denials, reduced reimbursements, or audit risk. Proper use of modifiers is key to accurate billing and to ensure that the maximum amount of reimbursement is received.

The Importance of Accurate Modifier Usage, Including Modifier 59
Modifiers serve a critical role in medical billing, providing additional information that helps to clarify the services provided and support proper payment. Modifier 59, in particular, is used to indicate that a service was distinct or separate from other services performed on the same day. However, using Modifier 59 can be a bit tricky, and medical billers should take care to apply it correctly. To ensure accurate modifier usage, be sure to:
- Understand the definitions of each modifier and their appropriate usage
- Verify that the documentation supports the use of the modifier
- Ensure that the modifier is correctly applied and reported on the claim
- Stay up-to-date on guidance and changes related to modifiers
| Modifier | Description | Usage |
|---|---|---|
| Modifier 59 | Distinct Procedural Service | Used to indicate that a service was distinct or separate from other services performed on the same day. For example, if a patient received a surgical procedure on their right leg and another surgical procedure on their left leg, Modifier 59 could be used to indicate that the two procedures were separate and distinct from each other. |
| Modifier 25 | Significant, Separately Identifiable Evaluation and Management Service by the Same Physician or Other Qualified Healthcare Professional on the Same Day of the Procedure or Other Service | Used to indicate that a significant and separately identifiable E/M service was performed on the same day as a procedure or other service. For example, if a patient received a procedure and also had an E/M visit on the same day, Modifier 25 could be used to indicate that the E/M visit was separate and distinct from the procedure. |
| Modifier 51 | Multiple Procedures | Used to indicate that multiple procedures were performed during the same surgical session. For example, if a patient underwent multiple procedures during a single surgical session, Modifier 51 could be used to indicate that multiple procedures were performed. |
Improving coding accuracy in medical billing requires a combination of knowledge, skill, and attention to detail. By staying informed, following best practices, and avoiding common mistakes, you can help ensure that your medical billing is accurate, complete, and timely.
