The Procedure Coding System is a specialized classification used only in U.S. inpatient hospital settings for reporting medical procedures.

How is ICD-10-PCS structured?

Every PCS code is exactly 7 characters long. Each position (axis) defines a specific attribute, such as the body system or root operation.

How are ICD-10-PCS codes built?

Codes are constructed from tables rather than a static list. This ensures that every unique procedure can be accurately captured by a unique code.
