- Coding, Classification
From the Preface:
This sixth edition of the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) is being published by the United States Government in recognition of its responsibility to promulgate this classification throughout the United States for morbidity coding. The International Classification of Diseases, 9th Revision, published by the World Health Organization (WHO) is the foundation of the ICD-9-CM and continues to be the classification employed in cause-of-death coding in the United States. The ICD-9-CM is completely comparable with the ICD-9. The WHO Collaborating Center for Classification of Diseases in North America serves as liaison between the international obligations for comparable classifications and the national health data needs of the United States.
The ICD-9-CM is recommended for use in all clinical settings but is required for reporting diagnoses and diseases to all U.S. Public Health Service and the Centers for Medicare & Medicaid Services (formerly the Health Care Financing Administration) programs. Guidance in the use of this classification can be found in the section "Guidance in the Use of ICD-9-CM."
ICD-9-CM extensions, interpretations, modifications, addenda, or errata other than those approved by the U.S. Public Health Service and the Centers for Medicare & Medicaid Services are not to be considered official and should not be utilized. Continuous maintenance of the ICD-9-CM is the responsibility of the Federal Government. However, because the ICD-9-CM represents the best in contemporary thinking of clinicians, nosologists, epidemiologists, and statisticians from both public and private sectors, no future modifications will be considered without extensive advice from the appropriate representatives of all major users.
All official authorized addenda through October 1, 2011, have been included in this sixth edition.
Partial Code Freeze for ICD-9-CM and ICD-10 Finalized
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 which would end one year after the implementation of ICD-10. The implementation of ICD-10 was delayed from October 1, 2013 to October 1, 2014 by final rule CMS-0040-F issued on August 24, 2012. Links to this final rule may be found at http://www.cms.gov/Medicare/Coding/ICD10/Statute_Regulations.html .)
There was considerable support for this partial freeze. 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 and October 1, 2013 there will be 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, 2014, 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, 2015, regular updates to ICD-10 will begin.
The ICD-9-CM Coordination and Maintenance Committee will continue to meet twice a year during the partial freeze. At these meetings, the public will be asked to comment on whether or not requests for new diagnosis or procedure codes should be created based on the criteria of the need to capture a new technology or disease. Any code requests that do not meet the criteria will be evaluated for implementation within ICD-10 on and after October 1, 2015 once the partial freeze has ended.
