DRG 864 Overview
DRG 864 covers admissions primarily for fever and inflammatory conditions, including systemic inflammatory responses, undifferentiated febrile illnesses, and related diagnostic evaluation and management. These cases often involve broad-spectrum testing, antimicrobial management, and supportive care, which can drive resource use during an inpatient stay. For Medicare payment, classification under this Diagnosis-Related Group groups similar clinical presentations to determine bundled reimbursement for hospital services. Accurate documentation of presenting symptoms, infectious workup, and any complications is central to correct assignment and payment.
