Understanding Commonly Used Modifiers and Their Impact on Reimbursements

Apart from selecting the appropriate ICD-10, CPT, and the circumstances surrounding HCPCS codes, the correct utilization of modifiers plays a significant role in billing accuracy. These modifiers provide additional information about a procedure or service, helping to clarify a claim. Navigating the complexities of applying modifiers in medical billing can be daunting. Each third-party payer has its guidelines for using modifiers in conjunction with HCPCS and CPT billing codes. To ensure accurate code, modifier assignment, and prompt reimbursement, outsourcing medical billing services to experts is a wise choice.

In this article, we will delve into commonly used modifiers, their significance, and how they can affect reimbursement in the healthcare industry.

Modifiers in Medical Billing, Role & Importance of Modifier in Medical Coding

What is a modifier in medical billing?

Modifiers are two-character codes added to Current Procedural Terminology (CPT) or Healthcare Common Procedure Coding System (HCPCS) codes to provide additional information about a service or procedure performed. They offer a more detailed description of a medical service, thereby influencing reimbursement and claim adjudication.
Laura Reeds, director of coding compliance at IASIS Healthcare in Franklin, Tenn, says, "They are important tools in medical coding." The CMS-1500 and UB-04 claim forms, widely used in healthcare billing, provide space for up to four modifiers.

Examples of modifiers in medical coding

Example 1: During a wrist repair surgery (CPT code 25607), a concurrent procedure, carpal tunnel release (CPT code 64721), is performed. To accurately reflect this, it's essential to apply modifier 51, signifying that the secondary procedure was conducted alongside the primary one.
Example 2: If a patient had a knee injection (20610) and a separate shoulder injection (20670) on the same day, modifier 59 may be used.

When is the modifier used in medical billing?

The CPT code book offers guidance on situations in which the use of a modifier may be warranted:

1. When a procedure involves both professional and technical aspects.
2. When the service or procedure addresses more than one anatomical location.
3. In cases where multiple providers have participated in delivering the procedure.
4. If a service or procedure is administered to the patient on multiple occasions.
5. When a procedure is performed bilaterally.
6. When the provided service or procedure deviates from the standard code requirements, either by increasing or reducing it.

Types of Modifiers in Medical Billing

Level I Modifiers (CPT Modifiers)

Level I Modifiers, or CPT Modifiers, consist of two numeric digits and are copyrighted and annually updated by the American Medical Association (AMA). They are appended to the end of a CPT code using a hyphen, which is crucial in providing essential information for claims processing. They convey details such as whether multiple procedures were conducted, the medical necessity of a procedure, the specific anatomical location where the procedure was performed, and the involvement of multiple surgeons in a surgical procedure, among other pertinent information.

Modifier 25 This modifier indicates that a separately identifiable evaluation and management (E/M) service was rendered on the same day as another procedure or service.

Do not include the 25 modifier when an office visit solely involves an evaluation and management (E/M) service without any accompanying procedure.

Avoid applying the 25 modifier when billing for services conducted within a postoperative timeframe if they are directly connected to the previous surgical procedure.

Refrain from attaching the 25 modifier to an E/M service when a minor procedure is conducted on the same day unless the level of service can be distinctly justified as significant and separate.

Modifier 59: Distinct procedural services, preventing them from being bundled together.
Modifier 22: Increased procedural services
Modifier 50: Bilateral procedure
Modifier 51: Multiple procedures on the same day
Modifier 55: Follow-up care only
Modifier XE: Separate encounter, distinct service
Modifier 76 and 77: Repeat procedures during the same session or on the same day by the same provider
Modifier -62: Procedures performed by two surgeons working together as primary surgeons.

Level II Modifiers (HCPCS Modifiers)

Level II Modifiers, also called HCPCS modifiers, are composed of alphabetic characters or alphanumeric combinations with a letter as the initial character of the code. These modifiers, copyrighted and updated by the Center for Medicare & Medicaid Services (CMS), serve a similar purpose as CPT modifiers. They provide supplementary information about a medical procedure or service without altering the fundamental definition of the service itself.

• Modifier -E1: Used to indicate a lower left eyelid service.
• Modifier -RT and -LT: Indicate right and left sides, respectively.
• Modifier -NU: Denotes new equipment.
• Modifier -RR: Signifies rental equipment.

Role of Modifiers

Modifiers are extra details added to CPT and HCPCS codes to give more information about a medical procedure or service when submitting a claim. These modifiers don't alter the core meaning of the code. Essentially, they help clarify situations where a medical service or procedure didn't precisely match the code description, but the code itself is still applicable. Modifiers help explain why a healthcare professional performs a particular service or procedure.

Using Modifiers in Medical Billing- Key Points

Modifiers provide crucial details about the procedure, which can influence payment/reimbursement.
Categorization
Modifiers are classified into two primary categories:

1. Pricing Modifiers: Also known as payment-impacting or reimbursement modifiers, these modifiers directly affect the pricing and reimbursement for the reported code. On the CMS 1500 claim form, 24D is the appropriate place for this.
2. Informational Modifiers: These modifiers, also called statistical modifiers, while not primarily impacting payment, convey important information. They can still influence whether a specific code is eligible for reimbursement, making them relevant to the payment process.

Sequence Matters for Medicare Billing
When billing Medicare, it's essential to prioritize the HCPCS modifier by listing it on the claim form. The informational modifier should be listed second.
Documentation is Key
The mere placement of modifiers after CPT or HCPCS codes does not guarantee reimbursement. Payers may request medical documentation to validate the appropriate use of the assigned modifier.
Accuracy is Crucial
Correct usage of modifiers is imperative. Failure to include modifiers or improper use can result in claim rejection or denial. Furthermore, misuse of modifiers can trigger audits and noncompliance issues, particularly when billing government programs such as Medicare and Medicaid.
Compatibility of Modifiers
It is essential to note that certain HCPCS modifiers may not be compatible with specific CPT modifiers.
For instance, CPT modifier -50 indicates a bilateral procedure, while HCPCS modifiers -LT and -RT specify the side of the body where the procedure is performed.
CPT modifier -50 and HCPCS modifiers -LT and -RT are mutually exclusive.

NCCI Modifiers

A Modifier Associated with NCCI PTP (National Correct Coding Initiative Procedure-to-Procedure) is a specialized modifier acknowledged and approved by Medicare and Medicaid for utilization in situations with valid clinical reasons to override or bypass an NCCI PTP edit. This process of overriding edits is commonly referred to as "unbundling." Modifier 59 is an example of the modifiers available for bypassing NCCI edits.

How the use of modifier affects the reimbursement amount?

It is important to emphasize that applying different modifiers can significantly impact the reimbursement rates for various diagnostic procedures and surgical interventions. For instance, when the CPT Code Modifier 22 is employed, the payer will disburse compensation at a rate 110% higher than the standard reimbursement rate to the performing surgeon or diagnostic specialist. Conversely, the utilization of CPT Code Modifier 50 signifies the repetition of the same procedure, resulting in a reimbursement rate elevated to 150% of the initial baseline reimbursement rate.
Nevertheless, it is also essential to know how can the incorrect use of modifiers affect reimbursement of claims. Inadequate or inaccurate utilization of modifiers can lead to insurance payers denying or rejecting claims. Healthcare establishments are susceptible to experiencing aged accounts, write-offs, and revenue loss when they lack a comprehensive understanding and control over the appropriate application of modifiers.
