ICD-10 Coordination and Maintenance Committee
Effective October 1, 2015, ICD-10-CM and ICD-10-PCS replaced ICD-9-CM as the HIPAA adopted code set for medical diagnoses and inpatient acute care procedures. As of the March 19, 2014 the ICD-9-CM Coordination and Maintenance Committee was renamed the ICD-10 Coordination and Maintenance Committee. A representative from the National Center for Health Statistics (NCHS) and one from the Centers for Medicare and Medicaid Services (CMS) co-chair the ICD-10 Coordination and Maintenance Committee meetings. Responsibility for maintenance of the ICD-10 is shared between these two agencies, with NCHS having lead responsibility for ICD-10-CM for diagnoses and CMS having lead responsibility for ICD-10-PCS for inpatient acute care procedures.
The ICD-10 Coordination and Maintenance Committee is a Federal interdepartmental committee. Suggestions for modifications come from both the public and private sectors. Interested parties must submit proposals for modification prior to a scheduled meeting. 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.
Proposals for a new code should include:
- Description of the code(s)/change(s) being requested
- Rationale for why the new code/change is needed (including clinical relevancy)
- Supporting clinical references and literature should also be submitted.
Proposals should be consistent with the structure and conventions of the classification.
For proposal samples, see proposal documents from previous meetings in Summary and Proposals.
Once proposals are reviewed all requestors will be contacted as to whether the proposal has been approved for presentation at the Coordination and ICD-10 Maintenance Committee meeting or not.
- The ICD-10 Coordination and Maintenance Committee meetings are open to the public and held at CMS headquarters in Baltimore, MD.
- Registration is required by CMS using their meeting registration website. Registration opens approximately one month prior to the meeting.
- Approved proposals are presented and comments are encouraged both at the meetings and in writing. Recommendations and comments are carefully reviewed and evaluated, once the comment period has closed, before final decisions are made.
- Official code revision packages, which are referred to as addenda, are available from this website. Procedure addenda is available from the CMS website.
- The tentative agenda for the upcoming meeting will be posted here approximately one month prior to the meeting.
- Electronic copies of meeting materials (proposals and other handouts) are posted on this website just prior to the meeting to allow participants to download them. No paper copies of these materials are available at the meeting.
The ICD-9-CM Coordination and Maintenance Committee implemented a partial freeze of the ICD-9-CM and ICD-10 (ICD-10-CM and ICD-10-PCS) codes prior to the implementation of ICD-10. The partial freeze will end October 1, 2016. For more information about the code set freeze see ICD-9-CM website. There was considerable support for this partial freeze. On April 1, 2014, the Protecting Access to Medicare Act of 2014 (PAMA) (Pub. L. No. 113-93) was enacted, which said that the Secretary may not adopt ICD-10 prior to October 1, 2015. Accordingly, the U.S. Department of Health and Human Services issued a final rule on August 4, 2014 that changed the compliance date for ICD-10 from October 1, 2014 to October 1, 2015. The final rule also requires HIPAA covered entities to continue to use ICD-9-CM through September 30, 2015. Links to the final rule are provided at CMS website.
The partial freeze will be implemented as follows:
- The last regular, annual updates to both ICD-9-CM and ICD-10 code sets were made on October 1, 2011.
- On October 1, 2012, October 1, 2013, and October 1, 2014 there were only limited code updates to both the ICD-9-CM and ICD-10 code sets to capture new technologies and diseases as required by section 503(a) of Pub. L. 108-173.
- On October 1, 2015, there will be only limited code updates to ICD-10 code sets to capture new technologies and diagnoses as required by section 503(a) of Pub. L. 108-173. There will be no updates to ICD-9-CM, as it will no longer be used for reporting.
- On October 1, 2016 (one year after implementation of ICD-10), regular updates to ICD-10 will begin.
