What is modifier gp?

As an AI language model, I do not have personal experience with things like modifier gp. However, I can give some general information on medical coding and modifiers.

Modifier GP is used in medical coding to indicate that services were performed by a physical therapist or occupational therapist in a specific setting. It is typically used with Current Procedural Terminology (CPT) codes in the 97000-97799 range and appears as a two-character suffix to the code. The GP modifier indicates that the services were provided under the direct supervision of a licensed therapist.

Modifiers are used to provide additional information about a medical procedure or service that has been performed. They are used in conjunction with CPT codes to provide more detailed billing information for insurance purposes. Modifiers can indicate things like the type of service performed, the provider of the service, the location where the service was provided, and the time frame for the service.

It is important to use modifiers correctly in medical coding to ensure proper billing and reimbursement. If a modifier is used incorrectly, it can result in claim denials or payment delays. It is also important to ensure that the documentation supports the use of the modifier, as it may be audited by insurance companies or government agencies.
