**International      Classification of Diseases, Tenth Revision, Clinical Modification       (ICD-10-CM)**

**Note: ICD-10-CM is      currently undergoing revision, and it will not be available until late      2001. The draft version is no longer available. **

The National Center for      Health Statistics (NCHS), the Federal agency responsible for use of the      International Statistical Classification of Diseases and Related Health      Problems, 10th revision (ICD-10) in the United States, has developed a      clinical modification of the classification for morbidity purposes. The **ICD-10**      is used to code and classify mortality data from death certificates,      having replaced ICD-9 for this purpose as of January 1, 1999.       ICD-10-CM is planned as the replacement for  ICD-9-CM, volumes 1 and      2. 

The ICD-10 is      copyrighted by the **World      Health Organization (WHO)**, which owns and publishes the      classification. WHO has authorized the development of an adaptation of      ICD-10 for use in the United States for U.S. government purposes. As      agreed, all modifications to the ICD-10 must conform to WHO conventions      for the ICD. Except in rare instances, no modifications have been made to      existing three-digit categories and four-digit codes, with the exception      of title changes that did not change the meaning of the category or code. 

ICD-10-CM was developed      following a thorough evaluation by a Technical Advisory Panel and      extensive additional consultation with physician groups, clinical coders,      and others to assure clinical accuracy and utility. We believe the      clinical modification represents a significant improvement over ICD-9-CM      and ICD-10. The current draft of ICD-10-CM contains a significant increase      in codes over ICD-10 and ICD-9-CM. 

Notable improvements in      the content and format include: the addition of information relevant to      ambulatory and managed care encounters; expanded injury codes; the      creation of combination diagnosis/symptom codes to reduce the number of      codes needed to fully describe a condition; the addition of a sixth      character; incorporation of common 4th and 5th digit subclassifications;      laterality; and greater specificity in code assignment. The new structure      will allow further expansion than was possible with ICD-9-CM. 

The entire draft of the      Tabular List of ICD-10-CM, and the preliminary crosswalk between ICD-9-CM      and ICD-10-CM were made available on the NCHS website for public comment.      All comments received during the comment period, which began December 1997      and ended February 1998, were requested to be in writing. The 60 day open      comment period for the draft ICD-10-CM has concluded and the draft version      of the ICD-10-CM has been removed from the NCHS homepage.

An overview about the      comments received is available as a PDF file. **View      / download PDF** 18 KB

All of the comments      received are being reviewed. It is anticipated that the final version of      the tabular portion of the ICD-10-CM will be posted on the NCHS homepage      in late 1999. Until that time the ICD-10-CM is not available for      distribution or review, as it is undergoing changes. 

There is not yet an      anticipated implementation date for the ICD-10-CM. Implementation will be      based on the process for adoption of standards under the **Health      Insurance Portability and Accountability Act of 1996**. There will      be a two year implementation window once the final notice to implement has      been published in the Federal Register.      Please feel free to contact the individuals listed below with any      questions you may have:

Those interested in the      proposed new procedure coding system, ICD-10-PCS,  being developed as      a replacement for ICD-9-CM, Volume 3, should see the **Health      Care Financing Administration's Web site**.

We very much appreciate      your interest in ICD-10-CM.
