    Clinical & Coding Specifications

    Clinical Context

    A 72-year-old primary care physician requests a short specialist consultation about a recent change in a patient's anticoagulation regimen after a minor gastrointestinal bleed. The consulting cardiologist reviews the electronic health record, including recent labs, medication list, and endoscopy report, and communicates with the requesting physician via secure EHR messaging. The consultant documents a focused review, provides clinical recommendations about resumption and dosing of anticoagulation, and uploads a written report to the EHR for the requesting clinician. The encounter is non–face-to-face, initiated by the requesting clinician, and the consulting clinician spends at least five minutes providing clinical input and a written report back to the requester. Typical workflow includes an initial request from the treating clinician, chart review by the consultant, optional asynchronous electronic communication, and a finalized written consult note sent to the requesting clinician and filed in the patient's record.
