The Value Set is a combination of values from volume 3 from the Code System International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) and values in the Code System ICD-10 Procedure Coding System.

The International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) is based on the World Health Organization’s Ninth Revision, International Classification of Diseases (ICD-9). ICD-9-CM was the official system of assigning codes to diagnoses and procedures associated with hospital utilization in the United States.

The ICD-9-CM consists of:

• a tabular list containing a numerical list of the disease code numbers in tabular form;
• an alphabetical index to the disease entries; and
• a classification system for surgical, diagnostic, and therapeutic procedures (alphabetic index and tabular list).

The National Center for Health Statistics (NCHS) and the Centers for Medicare and Medicaid Services are the U.S. governmental agencies responsible for overseeing all changes and modifications to the ICD-9-CM.

The ICD-10-PCS is the replacement for ICD-9-CM, volume 3, effective October 1, 2015.

The ICD-10-PCS is a procedure classification published by the United States Centers for Medicare & Medicaid Services (CMS) (https://www.cms.gov) for classifying procedures
performed in hospital inpatient health care settings.
