ICD-10 Procedure Coding System

Source: Wikipedia, the free encyclopedia.

The ICD-10 Procedure Coding System (ICD-10-PCS) is a US system of

ICD-9-CM. ICD-9-CM contains a procedure classification; ICD-10-CM does not. ICD-10-PCS is the result. ICD-10-PCS was initially released in 1998. It has been updated annually since that time.[1] Despite being named after the WHO's International Classification of Diseases, it is a US-developed standard which is not used outside the United States.[2]

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.[3] There are no decimals in ICD-10-PCS[4]

Of the 72,081 codes in ICD-10-PCS, 62,022 are in the first section, "Medical and surgical".[5]
