A mechanism for identifying and defining physicians’ and hospitals’ services. Coding provides universal definition and recognition of diagnoses, procedures and level of care. Coders usually work in medical records departments and coding is a function of billing. Medicare fraud investigators look closely at the medical record documentation which supports codes and looks for consistency. Lack of consistency of documentation can earmark a record as “upcoded” which is considered fraud. A national certification exists for coding professionals and many compliance programs are raising standards of quality for their coding procedures.
