    Clinical & Coding Specifications

    Clinical Context

    An established adult patient with a chronic condition (for example, type 2 diabetes with unstable glucose control or congestive heart failure with recent symptom change) initiates an asynchronous, non–face-to-face communication with a clinic’s qualified nonphysician healthcare professional (such as a nurse practitioner, physician assistant, or licensed clinical nurse specialist) via a secure patient portal message or an electronic assessment platform. Over the course of up to seven consecutive days, the clinician cumulatively documents problem assessment, review of medications and labs, and care plan adjustments totaling 21 or more minutes. The workflow includes triage by support staff, review of the patient’s electronic medical record, focused assessment questions, review of recent lab or device data, formulation of recommendations, and documented follow-up instructions. Communication may result in scheduled in-person visits, urgent referral, or medication changes; if synchronous audio/video is required, a separate telehealth visit code would apply. Typical site of service is the outpatient ambulatory clinic or virtual/telehealth setting where remote management of an established patient is provided by a qualified nonphysician clinician using an online E/M platform.
