Preface
The sixth edition of the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) was published in October 2007 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, 2007, have been included in this sixth edition.
