This test is based on the CPT Standard Edition code book and covers some of the basic parameters of CPT coding, both in a doctor's office environment and hospital setting. The test also covers the use of the CPT coding book to look up information and how to use the appendices and glossary to find answers. It also deals with some of the Medicare codes with modifiers that are used in billing today. * Having a 2015 CPT Standard Edition coding book available as a reference is recommended. For additional information regarding possible manuals, see the American Medical Association (AMA).
