ICD-10 Coordination and Maintenance Committee

The ICD-10 Coordination and Maintenance Committee (C&M) is a Federal interdepartmental committee comprised of representatives from the Centers for Medicare and Medicaid Services (CMS) and the Centers for Disease Control and Prevention's (CDC) National Center for Health Statistics (NCHS).  The committee is responsible for approving coding changes, developing errata, addenda and other modifications.  Requests for coding changes are submitted to the committee for discussion at either the Spring or Fall C&M meeting.

Coordination and Maintenance Committee Meetings

The Committee provides a public forum to discuss proposed changes to ICD-10.  The first day of the meeting is devoted to procedure code issues and is led by CMS.  The second day is devoted to diagnosis code issues and is led by CDC.  Tentative agendas for the meetings are posted one month in advance of the scheduled meetings. 

 A presentation is made at the C&M meeting, which describes the clinical issues and the procedure or technology. The participants at the meeting are encouraged to ask questions concerning the clinical and coding issues and to offer recommendations. Recommendations concerning proposed code revisions made both in person at the C&M meeting, and in writing before the end of the comment period, will be considered. Final decisions on code revisions are made through a clearance process within the Department of Health and Human Services. No final decisions are made at the meeting.
