About the ICD-10-CM Code

The ICD-10-CM code set in the United States is maintained by the ICD-10 Coordination and Maintenance Committee. This committee includes representatives from the National Center for Health Statistics (NCHS) and the Centers for Medicare and Medicaid Services (CMS). This committee reviews all requests for changes or additions to the code set. The Director of NCHS and the Administrator of CMS make the final coding data set decisions. Changes become effective October 1 of each year. A grace period for implementing the new ICD-10 codes is not provided.

HIPAA requires insurers to accept new diagnosis codes beginning October 1.

This 2019 supplement discusses only the coding changes for 2019. Last year, ACOG’s Committee on Health Economics and Coding published its guide, Diagnostic Coding in Obstetrics and Gynecology 2018.

The ICD-10 Coordination and Maintenance Committee approved the changes below for 2019.
