Evaluation and Management Coding
Evaluation and Management Coding (commonly known as E/M Coding or E&M Coding) is a medical billing process that practicing health care providers in the United States must use to be reimbursed by Medicare, Medicaid programs, or private insurance for patient encounters.
E/M standards and guidelines were established by Congress in 1995 and revised in 1997. It has been adopted by private health insurance companies as the standard guidelines for determining type and severity of patient conditions. This allows medical service providers to document and bill for reimbursement for services provided.
In 2010, new codes were added to the E/M Coding set, for prolonged services without direct face-to-face contact.
