This guide will cover everything healthcare practitioners need to know about orthopedic billing modifiers.

What Are Modifiers in Medical Billing?

Modifiers are two-character codes added to CPT (Current Procedural Terminology) or HCPCS (Healthcare Common Procedure Coding System) codes. They provide additional information about the procedure performed without changing the core meaning of the service. For Orthopedic Medical Billing, modifiers help convey specific details, such as whether a procedure was performed on multiple sites, during a different session, or if surgery was bilateral.

Types of Modifiers

• Level I Modifiers: Known as CPT Modifiers, these consist of two numeric digits and are updated annually by the American Medical Association (AMA). They supplement information or adjust care descriptions to provide additional details about the procedure or service.
• Level II Modifiers: HCPCS Modifiers consist of two alphanumeric characters (AA through VP) and are updated annually by the Centers for Medicare and Medicaid Services (CMS).
• Accurate orthopedic medical billing requires a thorough understanding of when and how to apply code modifiers. Modifiers indicate that a procedure was altered by specific factors, which can either increase or decrease reimbursement. Incorrect or missing modifiers can lead to claim denials or underpayments. Some modifiers are exclusive to Ambulatory Surgical Centers, some to physician practices, while others apply to both provider types.

Common Modifiers Used in Orthopedic Surgery Billing

Certain modifiers are frequently applied in orthopedic medical billing due to the nature of the treatments and procedures involved.

Some common examples include:

• GQ: Used when services are delivered via an asynchronous telecommunications system, where medical data (e.g., history, images) is collected and sent to specialists for review. Common in federal telemedicine programs.
• GT/95: Used for telemedicine services where the diagnosis or treatment is provided through live audio and video communication. Modifier 95 is the standard, but GT is used when specified by the insurance provider.
• G0: Used for telehealth services related to diagnosing or treating acute stroke symptoms.
• Modifier 24: Applied when a patient receives an unrelated evaluation or management (E/M) service during the post-operative period of major surgery (within 90 days) by the same physician. It is not used for procedures.
• Modifier 25: Commonly used in pediatrics, this is applied when an E/M service is performed on the same day as a major surgery by the same physician
• Modifier 26: Used when billing for the professional component of a service, such as a physician’s interpretation of a radiology scan, while the technical component refers to the equipment used.
• Modifier 27: Applied when a patient receives multiple E/M services at different outpatient facilities (e.g., emergency department, pharmacy) on the same day by the same or different physicians.
• Modifier 51: Used to bill for multiple procedures or surgeries performed by the same provider during the same session, including diagnostic imaging.
• Modifier 50: Indicates a bilateral procedure (performed on both sides of the body).
• Modifier 52: Used when a service or procedure is partially reduced or eliminated by the physician’s choice.
• Modifier 59: Indicates that a procedure is distinct and separate from other non-E/M services performed on the same day.
• Modifier 76: Used when the same procedure is repeated on the same day by the same physician after the initial procedure.
• LT/RT:
• LT: Indicates the procedure was performed on the left side of the body.
• RT: Indicates the procedure was performed on the right side of the body.

Using modifiers incorrectly or omitting them can lead to claim denials and lost revenue for healthcare providers. Proper use of modifiers is essential for ensuring accurate billing and avoiding revenue leakage.

How Modifiers Impact Reimbursements for Orthopedic Procedures

Modifiers play a critical role in determining reimbursement levels. Using the right modifier helps avoid underpayment or overpayment. For example, failing to apply Modifier 50 for a bilateral procedure might result in the insurance company reimbursing for only one side, leading to a lower payment. Correct modifier use ensures that practitioners receive the appropriate reimbursement for the services rendered.

Avoiding Mistakes in Orthopedic Modifier Billing

Using modifiers correctly is essential to avoid claim denials and revenue loss in Orthopedic Medical Billing. 

Here are some common mistakes and tips to avoid them:

• Incorrect 7th Character in ICD-10 Codes

Always choose the correct 7th character to reflect the patient’s current condition. For example, if a follow-up visit reveals a nonunion in a fracture, update the 7th character accordingly. Pay attention to documentation for accurate reporting.

• Pre-Assigning Diagnosis

Avoid assigning a diagnosis when the provider only suspects an illness or injury. Instead, use codes for the symptoms until tests confirm a diagnosis. For instance, if an ACL tear is suspected, code for knee pain and swelling, not the tear itself.

• Forgetting T-Codes

In cases involving prosthetic devices or complications, remember to use T-codes for accurate reporting. For example, if there’s mechanical loosening in a hip prosthesis, use the appropriate T-code from Chapter 19 of the ICD-10.

• Ignoring Parenthetical Note

Always read the parenthetical notes in the CPT codes. They often provide important information about bundled procedures or additional services like imaging guidance, which can prevent claim denials.

• Overusing Laterality Modifiers

Don’t add laterality modifiers (RT, LT) when the CPT code already specifies “bilateral.” For example, CPT code 73521 covers bilateral hip X-rays, so adding RT or LT will trigger a claim rejection.

By avoiding these common mistakes, you can ensure accurate coding, minimize denials, and maximize reimbursements.

Tips for Using Modifiers in Orthopedic Billing

Here are some best practices to keep in mind when applying modifiers:

• Stay Updated: Modifier rules can change, so it’s crucial to keep up with the latest Coding Guidelines.
