In medicine, coding refers to the application of codes to represent clinical information. In simple terms, it is the changing of narrative description of injuries, diseases and medical procedures into alphabetical or numeric designations. Coding providers give coding that can be used to describe diagnostic information that is in line with the patientдЫЄs condition, services offered and procedures followed. These codes are so detailed that they can provide an accurate description of the medical diagnoses and medical procedures performed. They can also correct diagnoses made. The profession of medical coding does not involve the practice of medicine. Instead, it is a simply the application of coding rules to a set of medical or clinical facts.
