    Clinical & Coding Specifications

    Clinical Context

    A 72-year-old male hospitalized on the medical ward following admission for acute decompensated heart failure. After initial inpatient evaluation and stabilization by the primary team, the patient requires a subspecialty cardiology follow-up consultation to assess persistent dyspnea, review response to diuretics, and adjust guideline-directed medical therapy. The cardiologist conducts a complex follow-up consultation via telehealth, spending approximately 35 minutes in real-time audio-video communication with the patient and the inpatient team, reviewing bedside telemetry, lab results, and imaging, and documenting recommendations in the inpatient record. The clinical workflow includes: initial chart review, coordination with nursing and the primary team to schedule the telehealth visit, the 35-minute synchronous telehealth encounter with the patient and/or surrogate at the bedside, documentation of findings and plan in the electronic health record, and communication of medication changes and follow-up testing to the primary team before discharge.
