About the 0D Body System
The ICD-10-PCS classification for the Gastrointestinal System within the Medical and Surgical section encompasses a wide range of root operations that describe various surgical procedures on digestive organs. These root operations define distinct actions performed on the gastrointestinal tract and related structures.
For example, Bypass (0D1) involves altering the route of passage through a tubular body part, while Dilation (0D7) expands the lumen of a gastrointestinal segment. Procedures like Drainage (0D9) remove fluids or gases, and Excision (0DB) cuts out a portion without replacement. The list also includes interventions like Insertion (0DH), which puts in a device to assist function without replacing body parts, and Repair (0DQ), which restores anatomical structure and function. More complex operations such as Transplantation (0DY) replace a part with tissue from another individual, and Resection (0DT) removes an entire body part without replacement. Understanding these root operations and their specific ICD-10-PCS codes ensures precise coding and documentation of gastrointestinal procedures.
Questions About This Page
How many codes are in the 0D body system?
The 0D body system contains 9,236 ICD-10-PCS codes in FY 2026, organized into 25 root operations. 9,186 of them are billable on inpatient claims.
What is a root operation?
The root operation is the third character of every ICD-10-PCS code and names the objective of the procedure. Drainage takes fluid out, Excision cuts out a portion of a body part, and Resection removes all of one. Picking the right root operation is the central skill of PCS coding, so each one above carries its official CMS definition.
