About the 10 Body System
The ICD-10-PCS root operations within the Pregnancy section of Obstetrics cover a range of procedures related to the management of pregnancy and its outcomes. These operations describe specific actions performed on parts involved in pregnancy.
For example, the Abortion operation (10A) refers to the artificial termination of pregnancy, while Delivery (10E) assists in the passage of the products of conception through the genital canal. Extraction (10D) involves pulling or stripping out all or part of a body part by force. Procedures like Insertion (10H) involve placing non-biological appliances to assist or monitor physiological functions during pregnancy. Other operations include Drainage (109) to remove fluids, Repair (10Q) to restore normal anatomy, and Transplantation (10Y) to replace tissue from another individual. Understanding these root operations and their specific purposes is essential for accurate obstetric coding and documentation.

How many codes are in the 10 body system?
The 10 body system contains 317 ICD-10-PCS codes in FY 2026, organized into 12 root operations. 305 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.
