This myriad of ICD-10-CM/PCS codes presents challenges and questions for thoracic surgery researchers and medical journal reviewers and editors when evaluating thoracic surgical outcomes research utilizing ICD-10-CM/PCS. In this review, we describe the development of ICD-10-CM/PCS and summarize how it applies specifically to thoracic surgery patients undergoing pulmonary lobectomy, sublobar resection (segmentectomy or wedge resection) and esophagectomy. As researchers begin using ICD-10-CM/PCS for outcomes research from administrative datasets, it is important to understand ICD-10-CM/PCS, as well as the strengths and challenges of these new classifications.



The recent implementation of the International Classification of Diseases, 10 th Revision, Clinical Modification and Procedure Coding System (ICD-10-CM/PCS) provides a robust classification of diagnoses and procedures for hospital systems.
