The Centers for Medicare and Medicaid Services, the agency responsible for maintaining the inpatient procedure code set in the U.S., contracted with 3M Health Information Systems in 1995 to design and then develop a procedure classification system to replace Volume 3 of ICD-9-CM.

Section structure

Each code consists of seven alphanumeric characters. The first character is the 'section'. The second through seventh characters mean different things in each section. Each character can be any of 34 possible values the ten digits 0-9 and the 24 letters A-H, J-N and P-Z may be used in each character. The letters O and I are excluded to avoid confusion with the numbers 0 and 1. There are no decimals in ICD-10-PCS Of the 72,081 codes in ICD-10-PCS, 62,022 are in the first section, "Medical and surgical".https://www.cms.gov/ICD10/Downloads/pcs_final_report2011.pdf
