Chapter 2 Introduction to ICD-10-PCS Review Exercises: Chapter 2 1. Answer: 0DJO8ZZ Character Section Body Syst em Root Ope ratio n Body Part Approach Device Qualifier
Explanation Medical and Surgical Gastrointestinal System Inspection
Upper Intestinal Tract Via Natural or Artificial Opening Endoscopic No Device No Qualifier
INDEX: Root Operation: Inspection. Index: Esophagogastroduodenoscopy (0DJ08ZZ) In this example, the complete seven character code is listed in the Index. The code still must be confirmed using the code Tables. EGD is an inspection procedure when no other procedures, such as a biopsy or excision, are performed with the EGD. Body part inspected is the upper intestinal tract. Approach is through the mouth so “via natural or artificial opening endoscopic” is the choice for this procedure. 2. Answer: 0HBU0ZZ Character Section Body System Root Oper ation Body Part Approach Device Qualifier
Explanation Medical and Surgical Skin and Breast Excision Breast, Left Open No Device No Qualifier
INDEX: When consulting the Index, the main term Mastectomy has two subterms: see Excision, Skin and Breast and see Resection, Skin and Breast. Since only part of the breast was removed, the root operation is Excision.
