Navigating New Reimbursement CPT Codes and Modifiers: A Guide for Health Systems

The landscape of medical billing and reimbursement is continually evolving, with new Current Procedural Terminology (CPT) codes and modifiers being introduced regularly. These changes are crucial for health systems to stay compliant with regulations, ensure accurate billing, and maximize reimbursement. This article provides an overview of the latest CPT codes and modifiers, offering insights on how health systems can integrate these updates into their billing practices effectively.

Understanding CPT Codes and Modifiers

  • CPT Codes are standardized codes used by medical professionals to describe the services and procedures performed. They are essential for processing insurance claims and ensuring that providers are reimbursed correctly.

  • Modifiers are two-character codes that provide additional information about a procedure, such as its complexity, whether it was bilateral, or if it was performed in a specific setting. They help to clarify the circumstances of a service or procedure and can influence reimbursement rates.

Key Updates in CPT Codes for 2024

For 2024, several new CPT codes have been introduced to address advancements in medical technology, emerging healthcare needs, and changes in clinical practice guidelines. Here are some noteworthy additions:

  1. Telehealth Services Expansion: With the rise of telemedicine, new codes have been added to cover various remote patient monitoring and virtual consultation services. For example:

  • 99453: Remote monitoring of physiological parameters (e.g., weight, blood pressure, pulse oximetry, respiratory flow rate).

  • 99454: Supply and provisioning of devices for remote monitoring.

  1. Behavioral Health Integration: New codes have been introduced to support mental health services, reflecting the growing emphasis on integrated care.

  • 96156: Health behavior assessment or reassessment.

  • 96167: Health behavior intervention, individual, face-to-face; initial 30 minutes.

  1. Advanced Diagnostic Imaging: As imaging technology evolves, new codes capture the latest procedures.

  • 71271: Low dose CT scan for lung cancer screening.

Important Modifier Updates

Modifiers are equally critical, providing context that can impact reimbursement. Recent updates include:

  1. Modifier 93: Synchronous telemedicine service rendered via telephone or other real-time interactive audio-only telecommunications system. This modifier ensures that audio-only visits, which have become more common during the COVID-19 pandemic, are recognized and reimbursed appropriately.

  2. Modifier FT: Unrelated evaluation and management (E/M) service by the same physician or other qualified healthcare professional during a postoperative period. This modifier indicates that the E/M service is unrelated to the procedure performed during the postoperative period.

  3. Modifier 25: Significant, separately identifiable E/M service by the same physician on the same day of the procedure or other service. This modifier is crucial when reporting E/M services that are above and beyond the usual pre- and post-operative care associated with a procedure.

Best Practices for Implementing New Codes and Modifiers

To effectively integrate the new CPT codes and modifiers, health systems should adopt the following best practices:

  1. Training and Education: Regular training sessions for coding staff and healthcare providers on the latest updates. This ensures that everyone is aware of the new codes and how to use them correctly.

  2. Documentation Accuracy: Emphasize the importance of detailed and accurate clinical documentation to support the use of new codes and modifiers. Proper documentation is critical for justifying the services provided and ensuring reimbursement.

  3. Technology Integration: Utilize advanced billing software that is regularly updated with the latest CPT codes and modifiers. This can reduce manual errors and streamline the billing process.

  4. Audit and Review: Implement regular audits to review coding accuracy and compliance. Audits can help identify any issues early and provide opportunities for corrective action.

  5. Stay Informed: Subscribe to updates from the American Medical Association (AMA) and other relevant bodies to stay informed about future changes in CPT codes and modifiers.


Staying updated with the latest CPT codes and modifiers is essential for health systems to maintain compliance and optimize reimbursement. By implementing robust training programs, ensuring accurate documentation, leveraging technology, and conducting regular audits, health systems can navigate these changes effectively. Keeping abreast of these updates not only ensures financial stability but also enhances the overall quality of care provided to patients.
