CPT code 99606 refers to which type of appointment?

CPT code 99606 is specifically used to denote a follow-up visit for established patients that lasts for 15 minutes. This code is used in the context of medication therapy management, indicating that the appointment is focused on reviewing and managing the patient’s ongoing medication therapy rather than initiating a new treatment or performing a comprehensive review for a new patient.

In a follow-up visit, the pharmacist may assess the patient's current medication regimen, address any issues that have arisen since the previous appointment, and make necessary adjustments to the therapy. This process plays a crucial role in helping to optimize medication use, ensuring that the patients are receiving their medications effectively and safely.

This particular distinction emphasizes the importance of continuity in care for established patients, promoting better health outcomes through regular monitoring and adjustments as needed. The other options would not fit the definition of this specific CPT code as they refer to different types of appointments or services.
