**Classification of Diseases**

There are two related classifications    of diseases with similar titles. The *International Classification of Diseases*(ICD)    is the classification used to code and classify mortality data from death certificates.    The *International Classification of Diseases, Clinical Modification* (ICD-CM) is    used to code and classify morbidity data from the inpatient and outpatient records,    physician offices, and most NCHS surveys. NCHS serves as the World Health Organization    (WHO) Collaborating Center for the Classification of Diseases for North America and in    this capacity is responsible for coordination of all official disease classification    activities in the U.S. relating to the *International Classification of Diseases*(ICD)    and its use, interpretation, and periodic revision. The Collaborating Center is also    responsible in North America for the family of ICD classifications, which includes the    International Classification of Impairments, Disabilities, and Handicaps (ICIDH).
