What does CPT code 99607 represent?

CPT code 99607 is identified as an add-on code used specifically for billing additional time spent in Medication Therapy Management (MTM) services. This code is meant to be used in conjunction with 99605 or 99606, allowing healthcare providers to report each additional 15-minute interval that they spend on MTM services beyond what is indicated by the primary codes. This structure is crucial for healthcare professionals to accurately capture the total time and complexity of care provided to a patient during the MTM process. Therefore, the distinction of 99607 as an add-on code enhances the ability to account for extended patient interactions that may exceed the initial time allowed under the primary service codes.
