As a physical therapist, providing quality care to your patients is your top priority. However, ensuring accurate billing is equally essential for maintaining a successful practice. One crucial aspect of physical therapy billing is the proper use of the GP modifier. In this blog post, we’ll dive into the intricacies of the GP modifier and provide you with tips for accurate billing.

What is the GP Modifier?

The GP modifier, short for “Physical Therapy Services Delivered Under an Outpatient Physical Therapy Plan of Care,” is used to indicate that a service was provided under a physical therapy plan of care. This modifier is appended to the appropriate CPT code when billing for physical therapy services.

When to Use the GP Modifier

The GP modifier should be used when:

  • The services are provided by a physical therapist or under the supervision of a physical therapist.
  • The services are part of a physical therapy plan of care.
  • The services are provided in an outpatient setting.

Importance of Using the GP Modifier

Using the GP modifier correctly is crucial for several reasons:

  1. Compliance: Proper use of the GP modifier ensures compliance with billing regulations and guidelines set by insurance providers and government agencies.
  2. Reimbursement: Accurate use of the GP modifier helps ensure timely and appropriate reimbursement for the services provided.
  3. Claim Denials: Incorrect or missing GP modifiers can lead to claim denials, which can negatively impact your practice’s revenue and cash flow.

Tips for Accurate GP Modifier Billing

Now that we understand the importance of the GP modifier let’s explore some tips for accurate billing.

Before providing physical therapy services, always verify the patient’s insurance coverage. Ensure that the patient’s plan covers physical therapy and determine if there are any specific requirements or limitations related to the GP modifier.
