Many entities say “ICD-10” when they actually are referring to ICD-10-CM and/or ICD-10-PCS. Technically they are not the same thing. ICD-10-CM is a clinical modification of the WHO’s ICD-10. ICD-10-CM and ICD-10-PCS are used in the United States to report diagnoses and procedures on electronic healthcare claims transactions in the U.S. ICD-10 is used around the world to classify diseases and other health problems from various forms of health records and vital records. In the United States ICD-10 is used to code data from death certificates.
The International Classification of Diseases and Related Health Problems (ICD) is used around the world for collecting, classifying and presenting mortality statistics. The revision of the ICD currently in use is the International Statistical Classification of Diseases and Related Health Problems 10th Revision (ICD-10).
In the U.S. ICD-10 was implemented for mortality coding and classification from death certificates in 1999. The National Center for Health Statistics (NCHS) developed a Clinical Modification (ICD-10-CM) for medical diagnoses based on WHO’s ICD-10 and Centers for Medicare and Medicaid Services (CMS) developed a new Procedure Coding System (ICD-10-PCS) for inpatient procedures. ICD-10-CM replaced ICD-9-CM, volumes 1 and 2, and ICD-10-PCS replaced ICD-9-CM, volume 3 effective with discharges and services performed on or after October 1, 2015.
At the May 2019 World Health Assembly Member States adopted ICD-11, and Member States will start reporting using ICD-11 January 1, 2022. A version of this ICD-11 was released on June 18, 2018 to allow Member States to prepare for implementation and it can be accessed on the WHO ICD website.
