A little less than one year ago, the U.S. health care system underwent one of its most significant changes since the implementation of Medicare and Medicaid, when ICD-10-CM was implemented on October 1, 2015. Although years of planning and preparations preceded this event, there were predictions of significant upheavals in the system, including the inability of payers to process claims, payment delays, cash shortfalls, potential practice closures or bankruptcies, interruptions to patient treatments, etc. In this short article, we will review the history of ICD-10-CM, its implementation and the actual effects of its adoption on the health care system.
The World Health Organization (WHO) is responsible for developing and updating the International Classification of Diseases (ICD) code set for worldwide use. Each country can modify that code set to meet its own purposes. In the U.S., the modified ICD code set is designated by the term “Clinical Modification,” or CM. While CPT codes identify what services physicians provide to patients, the ICD codes identify why those services were needed.
