Clinical & Coding Specifications
Clinical Context
A patient with complex medical needs is seen by a physician for an evaluation and management (E/M) service. After the face-to-face encounter, the physician spends a significant amount of time on a different day reviewing extensive medical records, consulting with other healthcare professionals, and preparing a detailed care plan. This non-face-to-face work is directly related to the ongoing management of the patient's condition and is necessary for high-quality care. The physician documents the total time spent on these activities, which exceeds 30 minutes but is less than 60 minutes, and reports CPT code 99358 for the first hour of prolonged service without direct patient contact.
