Common Language Description

The CPT® Code 99605 refers to a specific service provided by a pharmacist, known as medication therapy management (MTM). This service is characterized by a face-to-face interaction between the pharmacist and a new patient, lasting for an initial duration of 15 minutes. During this encounter, the pharmacist conducts a comprehensive assessment of the patient's medication therapy, which includes a thorough review of the patient's medical history and current medication profile. This profile encompasses both prescription and nonprescription medications, allowing the pharmacist to identify any potential drug interactions or medication-related problems that may affect the patient's health. The pharmacist's role is to optimize the patient's drug therapy, ensuring that the medications prescribed are effective and safe. This may involve making recommendations for adjustments to the medication regimen to enhance health outcomes and promote adherence to the treatment plan. It is important to note that this code is specifically designated for new patients, and there are additional codes available for established patients and for extended time spent on medication therapy management. For established patients, CPT® Code 99606 is used for a similar service lasting 15 minutes, while CPT® Code 99607 is applicable for each additional 15 minutes of service provided during either the initial or established patient encounter.
