The modifier -TC is a commonly used term in the healthcare industry, particularly in the context of medical billing and coding. It is used to indicate that a service or procedure was provided via telecommunication technology, such as video conferencing, phone call, or secure messaging. The use of telecommunication technology in healthcare has become increasingly popular, especially in light of the COVID-19 pandemic, which has accelerated the adoption of telehealth services.

The modifier -TC is used in conjunction with Current Procedural Terminology (CPT) codes, which are used to describe medical procedures and services. The modifier -TC indicates that a particular CPT code was used to describe a telecommunication-based service. For example, a telemedicine visit with a physician would typically be coded using a CPT code that describes the type of service provided, such as a routine office visit or a consultation, followed by the -TC modifier to indicate that the service was provided via telecommunication.

One of the main advantages of using the -TC modifier is that it allows healthcare providers to bill for telehealth services in the same way that they would bill for in-person services. This means that healthcare providers can be reimbursed for telehealth services at the same rate as they would for in-person services, provided that the services meet the criteria for reimbursement set forth by the payer.

Another advantage of using the -TC modifier is that it allows for more accurate tracking of telehealth services. By using this modifier, healthcare providers can differentiate between services that were provided in person and those that were provided via telecommunication technology. This can be useful for tracking trends in the use of telehealth services over time, as well as for identifying areas where additional resources or training may be needed to support the delivery of high-quality telehealth services.

In addition to the -TC modifier, there is also a modifier -95, which is used to indicate that a service was provided via synchronous telecommunication technology. This modifier is used to indicate that the service was provided in real-time, such as during a live video conference or phone call. The use of the -95 modifier is important because it is required by some payers for reimbursement of telehealth services.

It is worth noting that the use of the -TC and -95 modifiers is subject to specific rules and regulations that vary by payer and by state. For example, some payers may have restrictions on the types of services that can be provided via telecommunication technology, or on the geographic location of the patient or provider at the time of the service. It is important for healthcare providers to be familiar with the rules and regulations governing telehealth services in their state and with their specific payers in order to ensure compliance and maximize reimbursement.

In conclusion, the modifier -TC is an important tool for healthcare providers who provide telehealth services. It allows for accurate tracking and billing of telehealth services, and helps to ensure that providers are reimbursed for telehealth services at the same rate as they would be for in-person services. As telehealth services continue to grow in popularity, the use of the -TC modifier is likely to become even more important for healthcare providers seeking to provide high-quality care to their patients.
