What is ICD-10-PCS?

The ICD-10 Procedure Coding System (ICD-10-PCS) is a catalog of procedural codes used by medical professionals for hospital inpatient healthcare settings. The Centers for Medicare and Medicaid Services (CMS) maintain the catalog in the U.S. releasing yearly updates. The 2025 ICD-10-PCS codes are to be used for discharges occurring from October 1, 2024 through September 30, 2025.

Each ICD-10-PCS code has a structure of seven alphanumeric characters and contains no decimals. The first character defines the major "section". Depending on the "section" the second through seventh characters mean different things.
