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.

Guidance for Submission of Proposals:

  • Provide description of the code(s)/change(s) being requested including suggested placement within the ICD-10-CM classification structure.
  • Include rationale for why the new code/change is needed (including clinical relevancy.)
  • Proposals (including clinical justification) should be no longer than two pages.
  • Proposals should be consistent with the structure and conventions of the ICD-10-CM classification system.
  • Supporting clinical references and literature should be submitted with the proposal.
  • Indicate the name of persons or organization requesting the code changes as well as a designated primary point of contact with contact information.

Incomplete proposals will be returned to the submitter.  All proposals received will be acknowledged. However, acknowledgment of receipt, does not guarantee approval for presentation.

Once proposals are reviewed all requestors will be notified of the status of their proposal.  If the proposal is accepted to be presented, clinical presentations are welcomed. The clinical presentation should not include reference to the proposed ICD-10CM code changes or any reimbursement issues.

If PowerPoint slides are being used, the slides must be handicap accessible (508 compliant) as described in  www.section508.gov). PowerPoint slides should be received at least three weeks prior to the meeting.

Proposals are to be submitted to nchsicd10CM@cdc.gov by the C&M Meeting deadline provided on the webpage at Upcoming Meeting .

Partial Freeze of Revisions to ICD-9-CM and ICD-10-CM/PCS

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.external icon

The partial freeze was 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.
