About the 0H Body System
These medical and surgical codes cover procedures on the skin, breasts, nipples, nails and hair. The fourth character identifies the body part, including specific skin sites and right, left or bilateral breast values.
Procedures include cutting out part or all of a body part, pulling tissue off, destroying tissue, and removing solid matter. Others drain fluid or gas, divide a body part, or free it from a physical constraint. The tables also cover repair, replacement, reinforcement, reattachment, repositioning and transfer, as well as skin grafts and breast reconstruction. Device procedures include insertion, change, removal and correction. Other procedures examine a body part or modify its structure without changing its function.
Questions About This Page
How many codes are in the 0H body system?
The 0H body system contains 1,143 ICD-10-PCS codes in FY 2027, organized into 20 root operations. 1,123 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.
