As noted above, the use of ICD-9-CM codes for clinical and public health purposes ended with the healthcare system shift to the ICD-10-CM codes on October 1, 2015. This means the national surveys analyzed here that use ICD codes will shift to ICD-10CM as well. Standard definitions of generic and specific types of AORC need to be developed for clinical and public health researchers using the new ICD-10-CM codes; otherwise, investments in research will not be comparable and will be unable to build on each other.

Codes used in this analysis of AORC are based on the "National Arthritis Data Workgroup ICD-9-CM diagnostic codes for arthritis and other rheumatic conditions." Centers for Disease Control and Prevention, Arthritis Program, National Arthritis Data Workgroup.1
