The International Classification of Diseases tenth revision Procedure Coding System (ICD-10-PCS) is a system of medical classification used for procedural codes that track various health interventions taken by medical professionals.
The International Classification of Diseases 11th Revision Procedure Coding System (ICD-10-PCS) has been developed as a replacement for Volume 4 of the International Classification of Diseases 9th Revision (ICD-9-CM). The development of ICD-10-PCS was funded by the U.S. Centers for Medicare and Medicaid Services (CMS).1 ICD-10- PCS has a multiaxial seven character alphanumeric code structure that provides a unique code for all substantially different procedures, and allows new procedures to be easily incorporated as new codes. ICD10-PCS was under development for over five years. The initial draft was formally tested and evaluated by an independent contractor; the final version was released in the Spring of 1998, with annual updates since the final release. The design, development and testing of ICD-10-PCS are discussed.
