In this article we are going to discuss three types of codes that every medical coder will come across in his/her career.

A coder is a professional who will collect medical reports from a physician and turn that information (the condition of the patient, the diagnosis of the doctor, the prescription and any other procedure that the physician performed on the patient) into a set of codes.

There are three sets of code you’ll use on a daily basis as a medical coder.

  1. ICD
  2. CPT
  3. HCPCS

ICD 10 CM stands for International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) . This simply means that it is the 10th revision of the ICD code. The CM at the end of the code stands for clinical modification. The clinical modification revisions were put in place by the National Center for Health Statistics (NCHS). This clinical modification increases the number of codes to a great extent.

ICD-10-CM, contains over 68,000 codes.
