what does e/m stand for in medical terms
Evaluation and Management Coding Evaluation and management coding (commonly known as E/M coding or E&M coding) is a medical coding process in support of medical billing. Practicing health care providers in the United States must use E/M coding to be reimbursed by Medicare, Medicaid programs, or private insurance for patient encounters.[citation needed]
Ejection fraction In a healthy 70-kilogram (150 lb) man, the stroke volume is approximately 70 mL and the left ventricular end-diastolic volume (EDV) is 120 mL, giving an ejection fraction of  70⁄120, or 0.58 (58%).
